Hi, Before coding of a new patch, I prefer to ask here for your ideas and thus improve the changes of acceptance of the patch.
I posted before a patch to select which pid will carry the PCR timestamps. This makes sense in several scenarios: when using a non-video stream to carry PCR, when using multiple video streams, and son on. See it here: https://patchwork.ffmpeg.org/patch/12874/ However, this patch doesn’t support multiple programs, as only one stream can be specified. Therefore, I like to improve it to allow the selection of the PCR for each program. But, I’m not sure about what the best approach is. Here are some options: - Enhance the “mpegtsenc” muxer with a multi-program option for selecting the PCR. - Use the “-program” general parameter to mark which stream carries the PCR. Examples: $ “ffmpeg ... -f mpegts --progid_pcr_pid 1=101 ...” This indicates that for program with id 1 the PCR will be in the pid 101. $ “ffmpeg ... -program title=Prog1:st=0,pcr:st=1 -f mpegts ...” Here the first stream in the Prog1 will carry the PCR. Please comment on what you prefer/suggest. Regards. A.
