Interesting feature, experimentally implemented in mtn

I.e. produce a montage from a set of images

Fails on some files (gets stuck forever while capturing the first frame).

Happens often with Matroska. 1.0.7a introduced a workaround (-Wo) with ffmpeg’s argument order that worked with other file types.

When the resulting contact sheet is too thin, the meta-information header is cramped and fields overlap.

Timestamps could use some tweaking: e.g. centering on their background and rounded corners

Example given:

$ find $DIR \(-name "*.avi" -o -name "*.wmv" -o -name "*.mpg" -o -name "*.mp4" \) -exec vcs -dt -ds -n 12 -c2 -H 200 --jpeg --quiet {} \;

Works on avi, mpg and mp4 but fails on wmv with
Failed to capture frame (at second xxx.000)

Processing the same file directly works:

$ vcs -dt -ds -n 12 -c2 -H 200 --jpeg --quiet File.wmv

vcs hangs with some RM files.

Tracing shows it gets stuck in mplayer_identify.

MPlayer can play the files fine from the terminal. Although it exits with «MPlayer interrupted by signal 11 in module: uninit_vcodec».

I can reproduce the abrupt termination, it happens when using Real’s native decoder (w64codecs, /usr/lib/codecs/drvc.so). Using FFMpeg’s decoder (MPlayer’s -vc ffrv30) MPlayer exits normally.

I can’t reproduce the hang either way.
