[Ffmpeg-devel] [ bug ] converting png to dv gives solid black
Mon Mar 13 09:49:59 CET 2006
Can we all agree that:
No one likes NTSC (Never Twice the Same Color).
No one likes 30000/1001.
Lots of source material was recorded with NTSC and 30000/1001
so we are stuck with it.
and instead, think about:
> Instead it looks like pix_fmt conversion in ffmpeg has a bug.
> Basically, when I try the following:
> $ ./ffmpeg -i /tmp/checkerboard_3x3_%d.png -pix_fmt yuv411p -f yuv4mpegpipe test.yuv
> The test.yuv seems to be a solid black, even though no encoding is performed
> on a raw video.
> When I use png2yuv to convert your pattern to the test.yuv and later
> on use test.yuv for DV encoding everything looks fine.
