[SOLVED] Why does ffmpeg keep going?

[yetanotherlogin]

Hello

I used the same command I always use to combine a JPG and an MP3 file:

c:\>ffmpeg.exe -i audio.mp3
Input #0, mp3, from 'audio.mp3':
  Duration: 01:28:31.19, start: 0.025057, bitrate: 128 kb/s
    Stream #0:0: Audio: mp3, 44100 Hz, stereo, s16p, 128 kb/s
    Metadata:
      encoder         : LAME3.99r

c:\>ffmpeg.exe -loop 1 -i picture.jpg -i audio.mp3 -r 5 -vf scale=640:-1 -pix_fmt yuv420p -c:a copy -f mp4 output.mp4

But for some reason, ffmpeg keeps running even past the end of the MP3 file: After hitting CTRL+C to stop it, and playing the video, the video plays fine, and it's just silence past the 1hr20mn31s point. Any idea why?

Thank you.

You probably need something like -shortest to pick the shortest one

It used to work on older ffmpeg builds, then didn't work on newer ones, not sure about now. You might have to find an old version

-shortest (output)

Finish encoding when the shortest input stream ends.
