Technical Paper: H.264 Video Compression Standard EnGenius

Scalable Video Coding: (SVC) is the name for the Annex G extension of the H.264/MPEG-4 AVC video compression standard. SVC standardizes the encoding of a high-quality video bitstream that also contains one or more subset bitstreams (a form of layered coding). A subset video bitstream is derived by dropping packets from the larger video to reduce the bandwidth required for the subset bitstream. The subset bitstream can represent a lower spatial resolution (smaller screen)… Web* 需要注意的是本程序并不改变视音频的编码格式。 * * This software mux a video bitstream and a audio bitstream * together into a file. * In this example, it mux a H.264 bitstream (in MPEG2TS) and * a AAC bitstream file together into MP4 format file.
