I can reproduce a 30% overall speedup for this command
discard_pid can be quite expensive, so let's cache it and recalculate it on
every packet start.
ffmpeg -y -i samples/MPEG-VOB/sdtv/RAI.ts -c copy -map 0:v:0 -map 0:a:0 -f
mpegts /dev/null
Before:
1685 decicycles in handle_packet, 523483 runs,805 skips
After:
883 decicycles in
