[FFmpeg-devel] [bug/patch] MPEG-TS muxer: PCR not in sync with PTS/DTS

Please don't top-post on this list.
It is my understanding that the mpeg-ts muxer is supposed to generate
Constant Bitrate (CBR) transport streams. In the current code, the PCR
*always* starts at 0, so the behavior you call "a problem" is actually
the correct behavior.
One solution would be to add a new feature to the mpeg-ts mux so that
the initial PCR can be specified by the caller (using metadata?) or
maybe calculated from the first DTS received.
I'll work on a patch if Baptiste indicates he is OK with the concept.
