Description
ffmpeg -i test.264 -vcodec copy -an -f mpegts test.ts
Fails with errors.
Earlier builds did produce TS streams but playback was jittery.
I know this is already a known but but I'm submitting this in order to provide test material.
version N-38772-gc2e3b56
attached files will include:
test.pcap -- raw rtp session of H264 stream from a real-time encoder
test.sdp -- matching sdp file to the live feed
test.264 -- extracted raw H264 elementary stream from RTP feed, ie what is supposed to be able to be mux'd inside of ffmpeg. This is a H264 Main compliant stream (ie B frames).

RTP pcap file, can be replayed with sudo tcpreplay -i ethX test-short.pcap , I shortened this with dd, hopefully it still plays

Latest GIT of FFMPEg does fail to even process, however, earlier version of FFMPEG do process and create a failed TS. Regardless here is the "failed" response of the current GIT version.
