There's not even a hwaccel that can decode this. The dxva2/d3d11 hwaccels seemingly do, as does the qsv decoder. And being rarely used alone is not a reason to remove something. There needs to be some benefit to justify it (Simplifying maintenance, removing legacy code, etc). Also, p010 can be generated by swscale, and the only other software pixel format supported in this list is nv12, which is 8bit. If we remove p010, we would be making 10bit encodings not longer work with the output of software decoders as input, right? _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
