Ffmpeg can't find codec parameters while converting images to video

Question

I tried to use ffmpeg both from repos and from github. I tried this (also tried with -c:v some_codec ):

ffmpeg -f image2 -framerate 24 -pattern_type glob -i 'frame-*.jpg' -s WxH 'foo.avi'

Output #0, avi, to 'foo.avi':
Output file #0 does not contain any stream

Input images named like that:

frame1.jpg frame2.jpg  ...

Solution

Typo

Your inputs are named frame1.jpg, frame2.jpg, etc, but you have a typo in your command.

Change frame-*.jpg to frame*.jpg.

Zero padding

Because there is no zero padding in the file names (frame1.jpg vs frame01.jpg) the frame order may be incorrect when using the glob pattern. You can see the same effect using ls to view the files in the directory. To avoid this use the default sequence pattern instead:

ffmpeg -framerate 24 -i frame%01d.jpg output.avi

-f image2 is not needed.

Unrelated, but building with --disable-x86asm is not recommended as it may cause slowness.

Show the actual ffmpeg command you used and the complete console output.

@LordNeckbeard done.

[llogan]

What are the input files named? It's not finding them. Also, -s WxH is invalid: with -s you need to provide numbers, such as -s 1280x720 (or omit -s).

@LordNeckbeard it seems it works now, I had to write frame* instead of frame-*.
