  Disable writing SDT data? (mpegts)

  Posted by Jordan Johnson on January 3, 2014 at 9:26 pm

  I am attempting to mux transport streams from a Dshow capture and insert different PAT/PMT/TVCT tables into them. I use an external muxer for this. Issue is, the SDT table among others from ffmpeg overrides my external tables, TSReader detects the SDT tables from ffmpeg and its doesn’t read my mux properly.

  The mpegts muxer is this one. https://www.ffmpeg.org/ffmpeg-formats.html#mpegts

  If it helps, my command is this:
  C:ffmpeg -f dshow -r 30 -i video="vMix Video" -f dshow -i audio="vMix Audio" -c:v mpeg2video -profile:v 4 -level:v 8 -me_method epzs -threads 6 -r 29.97 -g 45 -bf 2 -trellis 2 -cmp 2 -subcmp 2 -s 1920x1080 -b:v 16M -top 1 -minrate:v 14M -maxrate:v 18M -c:a ac3 -ac 2 -minrate:a 192k -maxrate:a 192k -bufsize:v 128.4M -bufsize:a 64k -muxrate 18.9M -streamid 0:30 -streamid 1:34 -y -vsync 1 -f mpegts testmux.ts

  Thank you in advance. 🙂
