Christophe Gisquet	4ba45c189c	dpx: use aligned line starts SMPTE 268M-2003 specifies that each line starts at a 4-bytes boundary. Therefore, modify correspondingly the input buffer strides and size. Partially fixes ticket #3692: DLAD_8b_3c_big.dpx still has inverted colors, which might be related to endianness. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Georg Lippitsch	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.
