[FFmpeg-user] Concatenation of mpg files

[Dzung Nguyen]

The final video is not playable by VLC player and the movie player in
Ubuntu. It only shows the first subvideo.

Ah I forgot, the command also has time information -t:

ffmpeg -f image2 -loop 1 -r 29.97 -i resized0.png -t 60 -q:v 0 -r 29.97
0.mpg
ffmpeg -f image2 -loop 1 -r 29.97 -i resized1.png -t 60 -q:v 0 -r 29.97
1.mpg

cat *.mpg >out.mpg

I tried using concat demuxer before, but it keeps getting crashed/long time
when I concatenate 50 video files.
