Currently RGB and RGBA 12-bit are supported by DPX decoder only if component
values are padded (packing "Filled to 32-bit words, method A").
This patch adds decoding of RGB
and RGBA 12-bit with no padding (packing "Packed into 32-bit words").
I suggest we wait with this patch until we verified if RGBA dpx decoding
is broken (I suspect so, I believe you have a sample to verify).
Sorry, I see a line was missing in my first post, the one with the link
to the RGBA test file.
Test file for RGBA 12-bit packed:
https://github.com/MediaArea/RAWcooked-RegressionTestingFiles/tree/master/Formats/DPX/Flavors/RGBA_12_Packed_BE
Regression test done on
checkerboard_1080p_nuke_bigendian_12bit_alpha.dpx and
checkerboard_1080p_nuke_littleendian_12bit_alpha.dpx in
https://samples.ffmpeg.org/image-samples/dpx_samples.zip
As-is, we wouldn't do anybody a favour.
Thank you, Carl Eugen
