[FFmpeg-devel] [PATCH] libavfilter/vf_colorrange_cuda: CUDA-accelerated video filter for MPEG and JPEG color range conversions

Hello, This patch adds video filter which does color range conversion similar to swscale scaling filter. How to use it: ./ffmpeg \ -hwaccel cuda -hwaccel_output_format cuda \ -i /path/to/intput/file.mp4 \ -vf colorrange_cuda=range=mpeg \ -c:v h264_nvenc \ -y /path/to/output/file.mp4 Fr

Re: [FFmpeg-devel] [PATCH v2] avcodec/jpeg2000: Add support for High-Throughput JPEG 2000 (HTJ2K) decoding.

Ideally, what I wanted to achieve was following best practices of what I saw, most of the error reporting inside jpeg2000dec.c would log errors using s->avctx, in case of things like corrupt bitstream errors, I did want also the htj2k code to emulate this, and the only reason its present in jpeg20
