Alexander Strange <[email protected]> added the comment:
h264 crashes with vflip too.
dest_cb = s->current_picture.data[1] + (mb_x + mb_y * s->uvlinesize)
* 8;
points out of the picture if uvlinesize is negative.
Fixing this would complicate h264 slightly. Should codecs be required to
support this? Disabling direct rendering in vflip sounds like a better
fix to me.
