Sorry for spamming the list, but I've encountered another issue which
could indicate silent problems, I'd like to avoid in a production system:
When transcoding a file with the current git-version of ffmpeg, I
receive warnings that do not appear in earlier versions:

Running the following command with the old version of ffmpeg (v0.5.2
from Debian Squeeze repositories):
[code]
ffmpeg -i input-ffv1.avi -an -vcodec ffv1 delme.avi
[/code]
Works fine, without warnings:

However, running the same command with the current git-version
(N-35077-g7876f14), contains warnings:

The transcoding itself runs fine, in both cases.
I've tried searching for these warnings on the web, but none of them
referred to as where those warnings might come from.
Thank you for any information,
