[Motion-user] motion + ffmeg = dark movies

[Dr. M. J. C. <mj...@av...>]

Hi all,

I'm using the Fedora13-supplied motion and ffmpeg, which are:

motion-3.2.12-1.fc13.i686
ffmpeg-0.6-3.fc13.i686

I'm having a weird problem with the movies generated with:

ffmpeg_cap_new on
ffmpeg_cap_motion off
ffmpeg_timelapse 0
ffmpeg_bps 500000
ffmpeg_variable_bitrate 0
ffmpeg_video_codec mpeg4
ffmpeg_deinterlace on

on_movie_end /usr/bin/ffmpeg -itsoffset -1 -i %f -vcodec mjpeg -vframes 
1 -an -f rawvideo -s 150x100 %f.jpg; /usr/bin/ffmpeg -i %f -f -vcodec 
mpegvideo -an %f.mpg

The movies come out super-dark, and are almost unusable. But the 
thumbnails (generated by on_movie_end) are OK!

If I split the movie into individual jpegs, they come out OK too, using 
something like:
ffmpeg -i 38-50.avi splitup-%2d.jpg

I don't think it's a player problem, as I've tried vlc, totem, mplayer, 
etc. Has anyone seen anything like that? I know ffmpeg is famous for API 
weirdness...

For now, I've reverted to saving individual thumbnails, and disabled the 
movie feature.
