Description
Hi!
I've found following bug I think:
I try to create simple video file using a picture:
ffmpeg -loop 1 -f image2 -r 24000/1001 -i any_picture.png -r 24000/1001 -vframes 3168 -vf "fade=in:65:48,fade=out:3120:48" -f yuv4mpegpipe -pix_fmt yuv420p -an -sn -y any.file
And initial color is not black! It happens if I try to use 'fade in' and 'fade out' filters together with any output formats and any video codecs!
At the same time if I do:
ffmpeg -loop 1 -f image2 -r 24000/1001 -i any_picture.png -r 24000/1001 -vframes 3168 -vf "fade=in:65:48" -f yuv4mpegpipe -pix_fmt yuv420p -an -sn -y any.file
Initial color is black (without 'fade out')!

Do you think this is a regression?
Is this reproducible with current git head?
comment:2 by , 13 years ago
Yes I do. I think this is a regression.
My ffmpeg version is 0.10 from Packman (for OpenSUSE 11.4). I updated it yesterday on March 27th 2012.

Please test current git head and please either find the revision introducing the problem or name a working revision.

I've just updated ffmpeg to version 0.10.2. The color is the same - dark gray!

Replying to ssp43:
I've just updated ffmpeg to version 0.10.2. The color is the same - dark gray!
Please test current git head. All released versions have more bugs and less features than current git head, only use a release if you are not a user, but if you have to package FFmpeg for other people.
I don't know a working revision. I've never had to face this problem.
So you changed your mind, it is not a regression?
comment:6 by , 13 years ago
I said I think that this is a regression but I don't know exactly :).
But I know that it is a bug - the color must be black!
I'll try to compile current git head and let you know.
.....
I've downloaded, compiled and linked current git head of ffmpeg.

Please provide a minimal command line that allows to reproduce the issue together with complete, uncut console output for current git head.
