[FFmpeg-devel] [PATCH 5/5] libavcodec/jpeg2000dec.c: Remove log2_chroma check in pixel format selection

[gautamramk at gmail.com]

From: Gautam Ramakrishnan <gautamramk at gmail.com>

The log2_chroma_wh is derived from the sample separations of the
codestream if the file is a j2k codestream. Not sure if sample
separation is same is subsampling and whether using sample
separation values from the codestream to determine pixel format.
