ffmpeg-demuxer

Split Audio and Video bitstreams based on FFmpeg

Features

• demux1: Demux a FLV file to H.264 bitstream and mp3 bitstream.
• demux2: Demux a MPEG2TS file to H.264 bitstream and AAC bitstream.
• Use cmake for cross-platform build.

Notes

demux1

• It doesn't init Output Video/Audio stream's AVFormatContext. It just writes AVPacket's data to files directly.
• Tt's not suitable for some kind of bitstreams. For example, AAC bitstream in FLV/MP4/MKV Container Format(data in AVPacket lack of 7 bytes of ADTS header).
