Hi!
Attached patch fixes running fate with "--enable-shared --enable-gpl" on
Solaris, the linker searches "libpostproc" in a directory"-link=libpostproc".
Only tested on Solaris.

Really? It looks fairly well-defined to me, though esoteric
(the gamma ramp is basically like sRGB but with a much bigger constant,
and the 8-bit Y'CbCr scaling seems

You can create small samples with ImageMagick/GraphicsMagick otherwise
use google skills.

Unacceptable. If somebody has misunderstood something you wrote, then
you need to explain better.

Second thing I noticed is that flushing is broken for v4l2m2m encoders.

should return AVERROR_EOF instead of continuing with an empty AVPacket with
size=0.
Hope we can get this fixed.

After some investigation I came to the conclusion, that av_frame_get_buffer
does not allocate the buffers correctly.
1. frame->pix_fmt=AV_PIX_FMT_NV12 frame->width=64 frame->height=64
2. so we need a buffer with 2 planes of same size. First plane holds Y and
second plane holds U and V

Hi Moritz,
thanks for the quick reply. I tried to debug the problem already, but the
problem lies within
Before patch:
init nbits = 17, get 1 samples, average cost: 16105 us
After patch:
init nbits = 17, get 1 samples, average cost: 15221 us
