Hi Jerome, Thank you so much for this patch. I ran a quick test and ffmpeg and ffplay seems to decode these files just fine. I noticed that taking a short 12-bit sequence (i didn't even realise that they were big endian actually) from the Blackmagic Cintel Scanner turned into FFV1 version 3 in

[FFmpeg-devel] [PATCH] avcodec/dpx: Support for RGB and RGBA 12-bit packed decoding

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"). As I have no file with line boundaries not aligned
