Actually, I need to correct myself: once I specified '-tvstd pal'
on the ffmpeg command line (and switched the NTSC/PAL switch at
the backplate of the VCR), both problems are gone: I can record
768x576 in color.
For the archives, this is how I capture the video
(and audio, well synchronized) on OpenBSD 4.6:
ffmpeg -y -v 1 -tvstd pal -isync
-f oss -ar 48000 -ac 2 -i /dev/audio0
-f bktr -r 25 -s 768x576 -i /dev/bktr0
-vcodec rawvideo -acodec pcm_s16le /video/out.avi
That's a large file (raw video, raw audio),
which I can compress later.
Thanks to all
Jan
