Domestic Common bt stations, mostly RMVB, RMVB small size and good quality is my favorite format, but not being seen there with RMVB video copyright protection information. Most foreign websites is used XviD encoded AVI (http://www.mininova.org/), a slight increase in the quality of their size is generally under the RMVB twice (a film 700 ~ 1000MB), and recently the electric donkey already appeared with a copyright-protected videos (need to use a special player, to pay to watch), but have been found in other bt stations. As to the use WMV format videos on the few, and mostly some video clips, copyright protection in the WMV video on the more "spread", especially when a lot of copyright protection is asking you to open or even several dozens of rogue Web site (compared to people vomiting) in order to watch video (Microsoft would not have thought of a beginning of such use of DRM), so under normal circumstances is not under the WMV format video online is more a wise choice.

In accordance with DXVA specification, there are three kinds of hardware decode acceleration levels
1, MC acceleration (motion compensation, also previously mentioned that Pixel Prediction)
2, IDCT acceleration (previously referred to Frequency Transform) + MC speed
3, VLD acceleration (previously referred to the entropy decoding) + IDCT acceleration + MC acceleration + (deblocking fliter-loop Deblocking Filter)
In addition to comparing the old graphics card (for example, Geforce3) would then support the MC to accelerate, there is now GF6 / 7, X1000 series of the second stage, while the GF 8600/8500 third level support for H.264 acceleration, as well as the HD2000 series supports VC-1 / H.264 third level acceleration, of course, it also requires decoder support in order to be called.
When the player or decoder display DXVA (also known as DirectX VA), also represents the hardware acceleration has been opened.

DXVA (also known as DirectX VA) is the full name of the DirectX Video Acceleration (hardware video acceleration interface).
DXVA is a Microsoft and graphics chip manufacturers to the definition of a hardware interface specification. If a graphics chip to support DXVA hardware specifications, does not mean that it implements all the functions defined inside DXVA. However, one thing is certain: the definition for the DXVA functionality of each one, in line with DXVA specification graphics chip driver will tell the system to its hardware, this function is achieved or not achieved inside - this is a mandatory standard DXVA nature of requirements. The advantages of such an application does not have to spend time and effort to test the graphics card has a feature not implemented.
Similarly, if a decoder supports DXVA specification, it does not mean it can use all the features inside the DXVA specification combinations, it can choose its own ability to support, or want to support a combination of those features, while the other combination of functions perhaps to give up.
In addition, if a display driver chip, although the support by some kind of feature, but that the decoder chip, support for this feature is unstable, and easily lead to system crashes or error, then the decoder can also opt to use the chip, this kinds of functions.

Decoder, splitter, as well as the concept of DXVA

Decoder function is on the video or audio decompression. We know that both the original is the original video or audio, data are very impressive and huge, so we use the encoder to compress them, so that it can facilitate transmission and storage. When playing we will need to restore the picture or sound, which requires decompression, which is decoded. In which more complex video decoder:
Video compression technology, as we have said before there are many, each where there are a lot of official, third-party decoder, various decoder functions, screen, speed vary, but generally fall into two kinds of decoding device: hardware decoder and software decoder.
Hardware decoder is to use the driver brought decoder interface and the hardware itself is connected to the use of the functions carried by the video hardware decoding, which can reduce the load on the CPU in order to achieve smooth playback, as well as enhance the CPU multi-tasking capability.
In addition to hardware, software decoder is a decoder, all but the decoder, its biggest feature is the use of CPU general-purpose processing capabilities of its software decoding. Although the software decoding consuming CPU, but you can modify, upgrade, in the case of sufficient CPU resources is the best choice.
Separator function is to package together to restore the video, and audio out. Before we talked about a lot of packages, each package must correspond to a separator, in order to correct the separate video and audio decoder for decoding.
Separator There are many, under normal circumstances non-standard packaging format, where the regular players do not have the appropriate separator, such as MKV. The more well-known separator moonlight splitter, haali so.

Used in video coding MPEG2/VC-1/H.264
Officially recognized by the DVD Forum, HD DVD using a PS package, that is, Program Stream (program flow), which is used in DVD before, and MPEG2 Program Stream package is the same, PS stream suffix name is VOB, and EVO and so on. The BD in the absence of DVD Forum, the official certification cases, of course, not PS package, but the use of the MPEG2 other packages TS package, namely Transport Stream (TS), TS stream suffix named TS.
Reference Information: http://tech.sina.com.cn/h/2008-03-19/0600607783.shtml
MPEG2-TS format is characterized by the request from the video stream is either a fragment can be independently decode the beginning. Structurally speaking, TS is the main body from head composed of documents and to expand over the TS stream also includes the time stamp. So that regardless of what the format of VBR tracks easily through the time stamp to synchronize the image
MKV is a Matroska using short, it is a new multimedia package format, with the more common is the X264 + MKV.

7, DivX format (. Divx) (internal video encoder: divx)
Back in 1998, Microsoft developed the first one (and only) in the PC using the MPEG-4 (Note) encoder, which includes MS MPEG4V1, MS MPEG4V2, MS MPEG4V3 a series of coded cores. Where V1 and V2 is used to create AVI files, and even today it is the default as a Windows component. However, V1 and V2 of the encoding quality is not very good, until MS MPEG4V3 only began to improve, quality has been significant progress. But I do not know what Microsoft's intentions out to shift the MS MPEG4V3 video encoding core enclosed in only applies to Windows Media streaming media technology, that is, we often see the ASF streaming media file. ASF, while the paper has some advantages, but because of excessive closure can not be edited, has not been widely used. This has angered some of the video are not afraid of days is not afraid to delve into video encoding hackers and placed in a master. Later, these groups not only to break Microsoft's video encoding, but also a result of their changes, a new video coding was born. That is the most widely circulated Mpeg4 Encoder ─ ─ DivX3.11.
DivX encoded video files with its greatest extent, not only to restore the original DVD picture quality, but also allows you to select almost all formats of audio, including VBRMP3 even AC3! ! DIVx video coding technology is Microsoft's ASF to break the shackles of the various agreements, from Microsoftmpeg4v3 change from the use of MPEG-4 compression algorithm. DIVX to MPEG4 compressed video, MP3 compressed audio, and to AVI file (. Avi common or. Divx) format exists, Windows operating system, built under the WindowsMediaPlayer essentially be able to play such a file, simply download the MPEG4 - CODEC can be, but the original MPEG4 is not used by the extension of the AVI, so installed the Microsoft MPEG4CODEC after playing as the file format will still be out of the discriminant error, DIVX "official website" On this point, take Microsoft's MPEG4CODEC been modified, and developed a DIVXCODEC, installed only CODEC, can be successfully used WinDosMediaPlayer play DIVX format files.

6. FLV format (. Flv)
Flash MX ago, flash get into the video file is a one into a bitmap. As a result a huge file, limiting its scope of application. With the introduction of Flash MX's, Macromedia has developed their own streaming video format - FLV. This format is sorenson the basis of the company's compression algorithms developed out. sorenson companies also provide algorithms for the MOV format. FLV format can not only easily import Flash, the hundreds of frames of the movie and spent two seconds; the same time can also be rtmp protocol from Flashcom server, upflow air.
Love Q video search is achieved in this way to play streaming media.
Variety of users to upload video files, Love asked them into a unified video of the FLV format, available to users online to watch other video sharing web sites they use this approach. This approach addresses not available for download, but it can be downloaded through a variety of tools.

Note: (1) At present, the online video sites are adopting this video format. Such as Sina podcasts, 56, potatoes, cool 6, youtube, etc., without exception. FLV has become the mainstream of the current video file format.

5. ASF / WMV (Advanced Streaming Format) format (. Asf. Wmv) (video portion of the use of Windows Media Video encoding, WMV (Windows Media Video) is Microsoft's family of video codecs, including WMV 7, WMV 8, WMV 9, WPV 10 are based on mepg standard audio portion of the use of Windows Media Audio Coding)
Microsoft has introduced the Advanced Streaming Format (ASF, Advanced Streaming Format), is also a real-time transmission of multimedia in the Internet technical standards, Microsoft's corporate ambitions are large, hitu with the ASF to replace the QuickTime sort of technical standards. ASF's main advantages include: a local or network playback, scalable media types, component download, as well as the expansion and so on. ASF application of the main components is the NetShow server and NetShow players. Have an independent encoder media information compiled into a ASF stream, and then sent to the NetShow server, and then from the NetShow server will send the ASF stream to the network all the NetShow player, in order to achieve one-way broadcast or multicast. This is the real-time broadcast of Real systems are similar.

4. MOV format (QuickTime) (. Mov) (internal video coding mepg4)
Apple's QuickTime format is developed by an audio and video file format. QuickTime used to save audio and video information, and now it is, including Apple Mac OS, Microsoft Windows95/98/NT, including support for all major computer platforms. QuickTime file format support 25-bit color and support integration of the leading compression technology to provide more than 150 video effects, and with providing more than 200 kinds of audio and MIDI-compatible equipment, sound equipment. The new version of QuickTime further expansion of its original features, including Internet-based applications, the key features. To sum up, QuickTime because of a cross-platform, storage space requirements and other technical characteristics of small, widely recognized by the industry, has become the field of digital media software technology the de facto industry standard.

3. RM / RMVB (Real Media) format (. RMVB. RM) (internal video coding RVx)
RM format is a RealNetworks company has developed a new type of streaming video file format, which arm of a total of three generals: RealAudio, RealVideo, and RealFlash. RealAudio is used to transmit near CD-quality audio data, RealVideo is used to transmit a continuous video data, while the RealFlash is RealNetworks collaboration with Macromedia's recently introduced a high compression ratio of the animated format. RealMedia network data transfer rate according to the different development of different compression ratio, thus achieving a low rate of wide-area networks, real-time image data transmission and real-time playback. Here we mainly introduced RealVideo, which in addition to ordinary video file format playback, you can also tie in with the RealServer server, first of all by RealEncoder responsible for the existing real-time video files into RealMedia format, RealServer is responsible for broadcasting RealMedia video files . In the data transmission can be side by side to download RealPlayer to play video images, without having to do like most video file, you must first download and then to play. At present, Internet already many websites using RealVideo technology for live coverage of major events.

(2). Vob file is used to save all the MPEG-2 format for audio and video data, which includes not only the film itself, but also for the menus and buttons with pictures and a variety of sub-screen subtitles streams. . ifo file is used to control the playback of VOB files, in this file can be found in how to control. vob files in the data broadcast information. As the. Ifo file on the disc can be played normally essential, so all of the. Ifo files are saved with a copy of the same name. Bup files. In each DVD disc has a video manager (VMG), it is stored in VIDEO_TS.ifo file, save a CD-ROM of the global information, such as CD-ROM in which the region shows. At the same time, CD-ROM will also be used to display menu data stored in VIDEO_TS.vob file, when inserted into the drive when a CD player will first display this menu, most of the menu to specify the scene the audience, choose the language subtitling.

(1). DAT yes yes data stream format, that is, we are very familiar with VCD. Open VCD CD-ROM with a computer can be made to have a MPEGAV directory, which is similar to the MUSIC01.DAT or AVSEQ01.DAT named file. DAT file format is MPG, VCD burning software that will meet the VCD standard MPEG-1 files automatically convert generated.

First of all,. Dat file and. Mpg files are in line with the audio and video compression standards MPEG1 data stream (of course there will be no audio), but the size of their data differ from the sub. . dat file is engraved on the VCD disc data on CD-ROM in order to facilitate data access, so we followed the standard VCD recording, each data packet size of 2324 bytes, which is just one sector of storage space size. VCD disc is composed of one or more tracks. The first track is a small, 2048 bytes / sector data track, there is a iso9660 file system, usually containing Windows VCD player, but there may be other information (such as: image, text, etc.). If you have pictures, mostly songs of the catalog and production company's promotional picture. And after the second track of the backlog of unprocessed 2324 bytes / sector of the MPEG (movie) track, each sector contains an MPEG PS data packets without file system. Usually we see about 600 MB's. Dat files, in fact, it is not a file, which is the so-called ISO channel, is used to enable Windows to handle such a track (Windows simply does not allow programs direct access to the raw device). During playback, CD-ROM drive will be the order of reading for each fan, but to form a continuous MPEG (movie) data streams. Thus, under Linux you can not copy or play these files. The. Mpg file is not prepared to carved VCD disc data. Therefore, packets can be large also can be very small. Often encounter such a situation, the whole. Mpg file is a data packet.

2. MPEG / MPG / MPA / DAT format (. Dat. Vob. Mepg, etc.) (coded mepg1 2 4)
Is the Moving Pictures Experts Group (Moving Picture Experts Group) is an abbreviation, by the International Organization for Standardization ISO (International Standards Organization) and IEC (International Electronic Committee) jointly established in 1988, dedicated to the moving images (MPEG video) and Audio Coding (MPEG Audio) standardization. MPEG motion picture compression algorithm is the international standard, is now almost all computer platforms common support. MPEG compression standard is designed for moving images, and its basic method is: in the unit time to collect and save the first frame of information, and then store the rest of the frame only to the relative change in the first frame part, so as to achieve the purpose of compression. MPEG, the average compression ratio of 50:1 up to 200:1, the high compression efficiency is obvious. At the same time the quality of picture and sound very good, and there is a uniform standard PC formats, the compatibility is very good. MPE standards include MPEG video, MPEG audio and MPEG systems (video, audio sync) in three parts, MP3 audio files is MPEG audio, a typical application, and Video CD (VCD), Super VCD (SVCD), DVD (Digital Versatile Disk ) is the full adoption of MPEG technology give rise to a new consumer electronic products.

Video Package Format:


1. AVI format (. Avi) (common internal video encoding mepg2, divx, xvid)
AVI professional name is Audio Video Interleaved (Audio Video Interleaved) format developed by Microsoft as a digital audio and video file format, originally used only for video of Microsoft's Windows operating environment (VFW, Microsoft Video for Windows), It is now directly supported by most operating systems. AVI format allows simultaneous video and audio playback intertwined, but not limited to compression standard AVI file, that is the same suffix name is AVI, but by a different compression algorithms, thus causing the AVI file format does not have compatibility. Generated by different compression standard AVI file, you must use the appropriate decompression algorithm to be out of play. This is a smooth playing some AVI and some are only silent images, or even the reasons for this can not be played.

9. WAV format which is uncompressed, it seems Needless to say, in the APE is not popular, when, WAV audio perfectionist who has always been the first choice, even now, if you want to make high-quality music, WAV is also no substitute for intermediates.

10. RM RM is already yesterday's story, nothing new, low-Bitrate ratio, but WMA, High Bitrate ratio, however MP3, although the new RM into the ATRAC3 algorithm, but the tide has been set it is difficult to make a comeback in.

8. APE and described above, several different encoding, this encoding provides the best sound quality assurance (lossless compression)! Also provides support for Winamp plug-ins can be directly used winamp to play. Refers to the so-called lossless compressed format and source files no difference in sound quality, while the Mp3, WMA, etc. The encoding scheme is based on detrimental and, in the loss part of the sound under the premise of saving storage space, so that even the best sound quality Mp3, WMA and can only be infinitely close to the source file sound quality. APE very suitable to encode particular about the details of solo tracks and large dynamic symphony. To you music fans (not fans) for the strongest recommendation! Its compression ratio is about 2:1.

7. ATRAC MD is using ATRAC (Adaptive TRansform Acoustic Coding Adaptive acoustic transform coding) compression algorithm, ATRAC currently only support the MD, ATRAC there is a derivative algorithm ATRAC3, OpenMG Jukebox is the use of such codes, encoded file name extension To OMG, can be used WINTEL architecture, computers, and ATRAC difference is that the average data rate to support different, there are 132,105,66 Kbits optional. This software can apply directly to the MD of some support MDLP models provide a direct output, so you can save a lot of recording time. OpenMG Jukebox set encoding, ripping, play, manage, and output in one, relatively large heads, but fairly easy operation. It uses the principles of the human ear shelter can effectively filter the human ear is not sensitive to the voice signals in order to achieve a higher compression ratio. The software documents the strict copyright protection can not be done as a free Mp3 copy and backup. If you have to support MDLP the MD, may wish to try the software.

5. OGG in high quality request, the damage the world of audio coding is a three-legged Xiang Li, namely, MP3, MPC, OGG. The support of a large number of new technologies, these codes have very good performance, are a group of supporters of their respective owners. The higher bit rates, OGG to show them the quality of which was very commendable, but OGG is also a big disadvantage is the high-frequency metal taste, which is somewhat disappointing.

6. MPC when the bit-rate 200k ~ 250k when you get in, MPC is the best I have come into contact with harmful code, and it is difficult to distinguish it and the number of differences between the original signal, in terms of frequency of a reservation or details of the reservation, as well as the distortion of the signal strength speaking, MPC can be called lossy compression of the king (this compression ratio). MPC is not a panacea, it can not encode 48khz sampling rate of the song, fortunately, such a source of very little tune. Unfortunately, this format is not as popular as mp3 or wma.

4. MP3PRO mp3PRO is entirely based on traditional mp3 encoding a modified itself the biggest technological highlight is that SBR (Spectral Band Replication band replication), which is a new audio coding enhancement algorithms. It offers to improve the low rate of Under the performance of audio and speech coding possible. This method can be specified bit rate to increase the audio bandwidth or improve the coding efficiency, SBR's greatest advantage lies in low data rates to achieve a very efficient encoding. If the high data rate circumstances, SBR would be a rubber stamp. When the production of mp3PRO file, the audio encoder is divided into two parts. Part of the audio data in the low-frequency part of the separation, through the traditional mp3 encoding technology derived from the normal mp3 audio stream, this would make the mp3 encoder can focus on the low-frequency signal and thus obtain better compression quality , and the original mp3 player can also play mp3PRO files. Another part of malpractices to separate the high-frequency band signal is encoded and embedded into the mp3 stream, the traditional mp3 player will be ignored out, and the new mp3PRO player can be restored from a high-frequency signals, and the two be combined, full-bandwidth, high-quality sound. the official claim that the adoption of such technologies can make mp3PRO encoding rate of 64kbps and 128kbps for mp3 to deliver the same quality. Conventional decoder can still capture the signal stream in which decode the mp3 to the neglect of SBR signal flow, but effects and ordinary 64kbps of mp3 no different, the new mp3PRO decoder can decode all of the complete audio signal flow, of course, can also be Decoding traditional techniques encoded mp3. Low bit-rate performance of mp3PRO obviously higher than the mp3, and WMA, but it is hard to say who wins, according to some HI-FI enthusiasts evaluation, mp3pro seems slightly better than some. Because of high bit-rate MP3 technology has developed very mature, almost perfect, and has such good as Lame encoding engine, mp3pro is not the opponent.

3. MP3 comes mp3 can not fail to mention LAME.LAME can be said to MP3 revolutionary history, what, MP3 sound quality is the most controversial issue, and very high-frequency losses, many mp3 encoders coarse coding algorithm not only resulted in high-frequency loss, but also lost a lot of details, like guitar strings rub the feeling is not found in the MP3. in the MP3 is about disappointment, LAME emerged, it supported the principle according to the human ear to analyze the shielding effect of waveform, with the VBR technology that allows sound to reach alarming proportions; its unique model of psychological sound reduction technology ensures the authenticity of the audio CD, with the VBR (dynamic bit-rate) and ABR (average bit rate) parameters, encoding MP3 sound out of pure thick, space broad, bass definition, detail good, sound quality is almost comparable to CD audio, but the file size is very small. Many User in the use LAME to reflect the post is this: immediately remove the hard disk all the MP3 and other encoders, all with Lame start over. Lame provides EXE and DLL, which DLL is a dynamic runtime library as a standard for other programs call. EXE is a Command Line program, the same as the DOS programs work, both independently of each other, unrelated. But we soon be able to find both the quality of coding is not the same, it is because of poor control dll, and adjust the parameters with rich EXE version compared to the effects of MP3 compression out of the rival. But the EXE is a command-line tool, the operation is very troublesome, thanks to WinLAMEr or lameGUIxp the Shell. Learn how to use them as long as the Shell (yes fool type, a look that will be), it can be compressed using LAME far the most exciting out of the MP3. Let me say APS, in the LAME appeared before the, APS is the best MP3 encoder, which uses the Fraunhofer IIS encoding algorithm, more than LAME encoding algorithm used in more advanced, in the under 192k Bitrate, even more than LAME-encoded song to be outstanding, is significantly rich in some of the details, but the APS itself does not support VBR, up to improve when the Bitrate, the sound quality should be worse than the LAME encoding, and most of the friends of the MP3's are usually 128-192K Bitrate, so APS is still there recommended value. In particular, there are many MP3 players do not support VBR and 256K Bitrate more than MP3, LAME will not necessarily fit these friends of the, APS has become a good choice, by its encoded song has never dishonored your expensive PLAYER.

Audio

1. WMA because it is Microsoft's work, must not be underestimated, WMA, as a shot in the arm for a streaming media format, like great progress. WMA files can flow in only 20K Bitrate provide audible sound quality, so WMA is often used for online listening and broadcasting as the first choice, Microsoft is already in Windows Media Player provides playback support. When the WMA's Bitrate up to 128k, almost all the damage at the same level encoding format of the Swordsman, MP3 at 128KBitrate time, there will be a clear high-frequency loss, but not WMA. But it seems that 128k is WMA a threshold, when the Bitrate upward increase, it will not have too much quality change (Microsoft's WMA, under the so-called 64kbits can achieve near CD sound quality is a True Lies), MP3 is not the same In 192K, the sound quality than the WMA could be better. Microsoft's WMA encoding release are mainly aimed at two goals, one is aimed at the network RM and RAM formats, the other is the user's hard drive in MP3. However, the high quality request, WMA still can not constitute a threat to MP3. If you want to be around 12:1 or higher compression ratio, you may wish to choose WMA format, at this flow rate, WMA outstanding too much. WMA and MP3's strengths and weaknesses has been the focus of our argument, in fact, this is an unanswerable question. It depends on your actual needs, is seeking a high quality (mp3) or a high compression ratio (wma).

2. VQF in the WMA is not popular before, VQF is a very popular format, because of its low bit-rate sound quality is better than MP3 (somewhat less than the WMA). Does not support "streaming" is the fatal weakness of VQF, which may also be why it now was completely suppressed a major cause of WMA.

7，Indeo video 5.10


This encoding scheme is also developed in the laboratory intel architecture, and it inherits the advantages of Indeo video R3.2, the corresponding file format is still AVI, decoding speed is also very fast. Windows ME/2000 comes with the Indeo video 5.1 of the Codec, a lot of games also apply to Indeo video 5.10 to encode their own animated demonstration. In the absence of DivX universal, is almost the most popular AVI encoding, and at the same time as Microsoft and intel support, this coding scheme has been widely adopted.

8，H.264


H.264 is also known as MPEG4-AVC, MPEG series of standards belong to ISO / IEC, in order to formulate the main body of international communications standards: ITU-T, the completion of H.263 (used for video conferencing streaming video standard) after the start of the development of more advanced H.264, and the newly enacted with the ISO / IEC body with hands and set up jointly by the two agencies called JVT (Joint Video Team) of the joint working group to MPEG-4 technology as the basis for more appropriate for video conferencing (Video Conference) use of derivative development, but also because it is jointly developed, and therefore known as the ITU-T in H.264, in the ISO / IEC for MPEG area is called MPEG-4 Part 10 (Part 10, also known as ISO / IEC 14496-10), MPEG-4 Part 10 by another name is MPEG-4 AVC (Advanced Video Coding, Advanced Video Coding), more than one name is an implication that the H. 264 = MPEG-4 Part 10 = ISO / IEC 14496-10 = MPEG-4 AVC.
Fortunately, in the end H.264 Which? Allow us to be MPEG-2, MPEG-4 (MPEG-4 Part 2), H.264 (MPEG-4 AVC, MPEG-4 Part 10) for resolution of the three performance comparison of bandwidth used, regardless of MPEG-2 , MPEG-4, H.264, all three can be up to 1920 × 1080i (non-interlaced) high-definition (High Definition, HD), 24fps (updated 24 pictures per second) and image quality, but the transmission bandwidth MPEG-2 needs 12 ~ 20Mbps, the relative H.264 as long as 7 ~ 8Mbps, while the MPEG-4 are somewhere between the two, more directly, if the bandwidth of the MPEG-2 used as a benchmark of 100%, MPEG - 4 To achieve the same effect only 60% of the bandwidth, H.264 is as low as 40%, or about the original MPEG-2 1 / 2 ~ 1 / 3.
It is worth mentioning that the use of the entropy decoding H.264 standard, there are two: one is content-based Adaptive Variable Length Coding (CAVLC) with a unified variable-length coding (CAVLC) with; the other is content-based self - adapted binary arithmetic coding (CABAC). CAVLC and CABAC adjacent blocks according to the current situation of block codes, in order to achieve better coding efficiency. CABAC compression efficiency than CAVLC, in the case of very quality can save about 20% of the bandwidth, but more complex.
