Comment (by James):
Replying to [comment:2 U. Artie Eoff]:
> hmm... 420 jpeg might be broken, too, with vaapi if file has exif
orientation.
Yes, pretty much any jpeg sample with orientation exif and any h264 stream
with Display Orientation SEI will be affected. What i did was make ffmpeg
look at codec exported display matrix instead of only container exported.
Does the following fix it for you?
