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')!
