Hi
You didn't
mux, you
converted.
That's why it took so long.
The FFmpeg command needed -vcodec copy -acodec copy.
When muxing, only takes a few seconds.
Should show info like this:-
Code:
Stream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #1:0 -> #0:1 (copy)
Download the video:-
Code:
youtube-dl -f 137 -o video.mp4 https://www.youtube.com/watch?v=qPK67Px8sR8
Download the audio:-
Code:
youtube-dl -f 22 -x -o audio.mp4 https://www.youtube.com/watch?v=qPK67Px8sR8
Mux them:-
Code:
ffmpeg -i video.mp4 -i audio.m4a -c copy "'Shallows' (Live @ Air Studios)1980p-192k".mp4
Result:-
Code:
@Xubuntu:~$ mediainfo "'Shallows' (Live @ Air Studios)1980p-192k".mp4
