Introduction: this is a document you can see on the Internet. It is used as an entry-level multimedia parsing document. The so-called Encapsulation Format is to put the compressed video track and audio track into a file in a certain format, that is, it is just a shell, you can also regard it as a folder for storing video tracks and audio tracks. In plain words, video tracks are equivalent to meals, while audio tracks are equivalent to dishes. The encapsulation format is a bowl or a pot, which

The ultimate decoding 2007 New Year version is a versatile, highly integrated decoding package, with three kinds of popular players (mpc/kmp/bsp) and WMP to provide good support, in simple, complex, English 3 language platform to achieve a variety of popular video audio perfect playback and coding functions. The recommended installation environment is Windows XP, DirectX 9.0C, Windows Media Player 9/10, IE6, windows9x is not supported, and if you want to use it under Vista, turn off the Vista UA

1. Encoding and Encapsulation formatCommon AVI, RMVB, MKV, ASF, WMV, MP4, 3GP, FLV and other files can only be regarded as a packaging standard.A complete video file is made up of 2 parts of audio and video. H264, XviD and so on is the video encoding format, MP3, AAC and so on is the audio encoding format.For example: A XviD video encoding file and a MP3 video encoding file in the AVI package standard package, you get an AVI suffix video file, this is

It is a popular video encoding method. It can be compressed by 2 ~ When MPEG2 has the same picture quality ~ 4 times, that is, if the size of a DVD Video is 1 GB, it can be reduced to about MB after H264 encoding. At the same time, H264 videos can also be used in trendy browsers (such as Firefox, Chrome, and ie9) play the video directly. If you want to burn a bunch of DVDs or HomeVideo (the old DV is genera

information in the AVI file format and calls it. Encoding introduction: There are many audio and video encoding solutions, which cannot be described as excessive. Currently, the following types of common audio and video encoding are available: MPEG series: (developed by the mpeg [Motion Image Expert Group] affiliated to ISO [International Standards Organization) Video Encoding mainly involves mpeg1 (which is used for VCD), MPEG2 (used for DVD), and MPEG4 (currently DVDRip uses its variants, suc

Two days ago, I used ghost to restore the system and re-installed some common software. At first, I didn't install fireworks. Then one day I had to process the images on my website before I thought of putting them on, however, it cannot be used when installed, and an internal error occurs when fireworks cannot be started. It won't work after several reinstalls, and no reason is found. After a long time, I thought of it. I searched for it on the Internet. Some other people on the Internet must ha
