Hi,
I reported https://trac.ffmpeg.org/ticket/9873 last week and have since
been digging into the code to see if I can get a patch together. I've
found the underlying issue in ff_frame_pool_video_init at line 77 of
libavfilter/framepool.c:
ret = av_image_fill_linesizes(pool->linesize
The frei0r API requires linesize to be width * 4.
Since the align property of ff_default_get_video_buffer2
specifies line alignment, not buffer alignment, the
previous value of 16 breaks this requirement for frames
whose width is a multiple of 8, but not a multiple of 16
as it adds extra padding to
