Following up on the previous attempts at YUVJ removal, this series implements full filter negotiation. It is WIP because I still need to go through the remaining AVCodec (which are not covered by FATE) and properly tag their colorspace and color range support. (See patch 19/25)
The rest should be good, though, so please feel free to review them with scrutiny. I decided to combine YUV range negotiation with YUV colorspace negotiation. Several important points: 1. We now explicitly ignore YUV metadata for non-YUV (RGB/XYZ/PAL) formats, as these have no hope of being useful. In particular, we force the colorspace to AVCOL_SPC_RGB, mostly for sanity/consistency. 2. We currently continue treating GRAY formats as forced full range, which is the swscale status quo. I have a separate series that adds full range negotiation to grayscale formats, but it is out of scope of this already ominous series. It was a delicate balancing act to get the new filter negotiation API integrated into all core filters (in particular vf_scale and vf_buffersrc) while maintaining forward and backward compatibility and not breaking FATE, but I managed to find an order that works, by first adding support to vf_buffersrc to make sure accurate metadata is available downstream _before_ we insert any conversion filters. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
