Package: compiz
Version: 0.6.3~git20071222.061ff159-1
Severity: normal
Having compiz active results in blank video using ffmpeg (both lenny and
experimental) for a/v recording. Not starting compiz as the window manager
(but the package is still on the system) and sticking with metacity restores
the desired functionality (recording tv) to ffmpeg.
The ffmpeg command-line I use (for the experimental ffmpeg, lenny uses
audio_device instead of oss) is:
/usr/bin/ffmpeg -y -tvstd ntsc -t "$TOTALSECONDS" -s 480x352 -re -deinterlace
-f video4linux2 -i /dev/video0 -f oss -i /dev/dsp -ac 2 -s 640x480 -f mpeg
-vcodec mpeg1video -acodec mp2 "$BASEFILENAME.mpeg"
with totalseconds and basefilename filled in, of course

The card or maybe the recording application may be incompatible with
compiz redirected windows, right. Probably not a bug in compiz then.
