Avi,It can contain videos of different encoding formats.
Encapsulate a file like a bottle
Originally, the original video stream data is converted into a corresponding bit stream after being encoded, And the bit stream is encapsulated into the corresponding file format according to the protocol. The so-called encapsulation is to add different "headers" to the original video bit streams and cut them into di

200:1;③ and MPEG-4 provide a high compression ratio at the same time, the loss of data is very small. Therefore, the application of mpeg-4 can greatly reduce the video storage capacity, obtain high video sharpness, especially for long-time video recording needs, but also has a good network transmission capacity in low bandwidth.Rm,rmvb:rm and RMVB are a kind of

signaling data include control of playback (playback, pause, stop), or a description of the status of the network. In the process of solving the protocol, the signaling data is removed and only the audio and video data are preserved. For example, data transferred using the RTMP protocol, after the protocol operation, outputs the FLV format data.
The function of the solution package is to separate the data of the encapsulated format into the audio str
