3cc0252732 vp8dec: reset loopfilter delta values at keyframes
while testing a VP8 encoder I found a mismatch between FFMPEG and libvpx
VP8 decoders. The reason for this mismatch is that FFMPEG doesn't reset
loopfilter delta values at keyframes. Patch that fixes the issue is below.
I've verified that the output of ffmpeg after this patch matches libvpx.

avctx->codec is not being set during parsing.

24778c32d8 Fix writing 12 bit DPX

05b7315412 Fix DPX decoder
Rewrite the DPX decoder to work with provided sample DPXs at
http://samples.ffmpeg.org/image-samples/dpx_samples.zip

The decoder could only decode 8 and 10 bit without alpha correctly,
failing or even crashing at other flavors. This patch aims to fix
these issues, properly decoding all variants of DPX provided in the
referenced DPX sample zip. For 10 and 12 bit, the alpha channel
is ignored, but decoding is still possible.
