Hi Moritz,
thanks for the quick reply. I tried to debug the problem already, but the
problem lies within libavcodec
I compiled ffmpeg with debug flags:
> ./configure --prefix="/opt/ffmpeg" \
>--pkg-config-flags="--static" --disable-programs --disable-doc \
>--enable-gpl --enable-static --enable-pic --enable-v4l2_m2m \
>--disable-optimizations --disable-mmx --disable-stripping --disable-a
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 interlea
Second thing I noticed is that flushing is broken for v4l2m2m encoders.
> avcodec_send_frame(enc_ctx, NULL);
should return AVERROR_EOF instead of continuing with an empty AVPacket with
size=0.
Hope we can get this fixed.

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

This commit adds configuration options to libvpxenc.c that can be used to
tune the sharpness parameter for VP8 and VP9.

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

Really? It looks fairly well-defined to me, though esoteric

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.
