Try something like:
Code:
ffmpeg -y -i "input.mp4" -c:v copy -an -sn -bsf:v h264_metadata=tick_rate=1001/60000:fixed_frame_rate_flag=1 -f rawvideo - | ffmpeg -y -fflags +genpts -i - -i "input.mp4" -map 0:v -map 1:a -c copy "output.m2ts"
But it seems there's a lot broken with ffmpeg so it may or may not work depending on the source...
