avcodec/pngenc: fix invalid read in sub filter.
...
First pixel was computed based on invalid address read, and then
corrected by the following memcpy. After the commit, it's not computed
anymore, and memcpy fills the appropriate area.
Fixes Ticket #3387

avcodec/exr: read layers
...
EXR files have, like tiffs, multiple channels and layers. I have a
patch for exr.c that allows you to select the layer you want to process
thru a -layer flag. It is not bulletproof but works for all layers that
have 3 channels in them (normals, motion vectors, etc).
The calling convention for ffmpeg is:
ffmpeg -layer Diffuse -i myexr.%d.exr test.mov
Here's an exr image with multiple layers:
