When checking pix_fmt mapping, some bitstreams are mapped to an incorrect pix_fmt instead of being rejected (ENOSYS). Actually, such bitstreams are not supported (FFmpeg encoder does not produce such bitstream, such bitstream may come only from another encoder for the moment). - JPEG 2000 RCT 11/13/15/16 bit depths are mapped to a 8-bit FFmpeg pix_fmt (e.g. bgr0), which is not expected. - JPEG 2000 RCT 9/10/12/14 bit depths with alpha are mapped to a FFmpeg pix_fmt without alpha (e.g. AV_PIX_FMT_GBRP9 for 9-bit with alpha), which is not expected. The order for choosing the pix_fmt is changed to the one used by YCbCr selection (<=8 bit first). " && !f->transparency" is added to the other lines.

FFmpeg README
FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.
Libraries
libavcodecprovides implementation of a wider range of codecs.libavformatimplements streaming protocols, container formats and basic I/O access.libavutilincludes hashers, decompressors and miscellaneous utility functions.libavfilterprovides a mean to alter decoded Audio and Video through chain of filters.libavdeviceprovides an abstraction to access capture and playback devices.libswresampleimplements audio mixing and resampling routines.libswscaleimplements color conversion and scaling routines.
Tools
- ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
- ffplay is a minimalistic multimedia player.
- ffprobe is a simple analysis tool to inspect multimedia content.
- ffserver is a multimedia streaming server for live broadcasts.
- Additional small tools such as
aviocat,ismindexandqt-faststart.

git format-patch or git send-email. Github pull requests should be
avoided because they are not part of our review process. Few developers
follow pull requests so they will likely be ignored.
