marm
Supports windowed/resumable transcoding of recorded media codec packets by:
- Reading stored/archived media packets (e.g. pcap'd rtp)
- Reconstructs media frames (e.g. depacketized encoded frame fragmented by network protocol)
- Synchronizing frame streams (e.g. paired audio and video)
- Muxing frame stream(s) to a container (e.g. mkv file) using libav*
- Detecting stitching information used to seamlessly resume transcoding
- ...
