"cannot identify image file %r" %

[jhemmmm]

I have been using vcsi for a long time. And i'd like to fix this issue.

The command "/usr/bin/vcsi /home/402c5ce63718915e685fa897dd5569a8 --grid-horizontal-spacing 0 --grid-vertical-spacing 0 -fast --quality 80 -w 852 -g 4x4 --metadata-position hidden -o /home/402c5ce63718915e685fa897dd5569a8poster_output.jpg" failed.

Exit Code: 1(General error)

Working directory: /home/apivcsi

Output:

Had the same issue. The temp file was 0 KB big.
Calling ffmpeg from the command line revealed a broken ffmpeg installation. Reinstalled ffmpeg, confirmed it was executable without error and vcsi worked without errors again.

Yes, ffmpeg works perfectly. I am using pre-build

I am experiencing this too. This is especially annoying because when I pass a list of files and it stops halfway through (I usually use it like this $ vcsi folder/**/*.mkv so I have to manually remove the file causing the issue, re-run vcsi, then put the file back. That said, thanks for working on vcsi!

I just had the same issue, seems like the cause is due to the duration of the file?
Reaching more than 18 samples is the issue in this specific file.

The following commands work fine:

vcsi -t -g 3x3 -w 905 *.mp4
vcsi -t -g 4x4 -w 905 *.mp4
vcsi -t -g 6x3 -w 905 *.mp4
vcsi -t -g 9x2 -w 905 *.mp4

The following throws the error:
vcsi -t -g 7x3 -w 905 *.mp4
vcsi -t -g 5x5 -w 905 *.mp4
vcsi -t -g 1x19 -w 905 *.mp4

I occasionally run into this error as well, it would be nice if vcsi would instead of failing completely just add a placeholder image for the erroneous frames, at least in the case if there's already a couple of frames that were calculated successfully.

A tip for those running into this issue when processing batches of files, you can add the --ignore-errors commandline switch which will cause vcsi to not stop the batch instead it will output a warning and skip to the next file in the batch.
