I'm trying to mux a video stream embedded in mkv from that mkv container to
mp4 container (ffmpeg -r 24000/1001 -i test.mkv -map 0:0 -c copy test.mp4).
Video stream has cfr 24000/1001 but ffmpeg thinks it is vfr. I tried the
solution from here https://trac.ffmpeg.org/ticket/4768 and force framerate
with -r. But that don't work. When I try to mux the raw h264 stream (ffmpeg
-r 24000/1001 -i video.264 -c copy test.mp4) I get this message: "pts has no
value time=00:02:38.19 bitrate=1312.4kbits/s speed= 154x" many times. Can
you help me?
