But since we're adding YUV range, we might as well add the YUV color matrix as well - since some codecs (e.g. VP8, JPEG) only support certain values. I decided to preserve the ambiguous and misleading "color_spaces" name, for symmetry with AVFrame.colorspace. (Though this would IMO be better called "color_matrix" or "color_system") I also decided to omit the other AVColor* fields for now, because vf_scale cannot handle auto-conversion between primaries/transfer/etc. There is little value in adding metadata we cannot do anything with, and no harm in extending the API again in the future. In theory, vf_scale can handle conversion between chroma locations, but also the signalling for this is annoying, so I'll defer it to a future commit. --- doc/APIchanges | 3 +++ libavcodec/codec.h | 6 ++++++ libavcodec/version.h | 2 +- 3 files changed, 10 insertions(+), 1 deletion(-) diff --git a/doc/APIchanges b/doc/APIchanges index 1f5724324a..7849ce47d9 100644 --- a/doc/APIchanges +++ b/doc/APIchanges @@ -2,6 +2,9 @@ The last version increases of all libraries were on 2023-02-09 API changes, most recent first: +2024-02-xx - xxxxxxxxxx - lavc 60.40.100 - avcodec.h + Add AVCodec.color_ranges and AVCodec.color_spaces. + 2024-02-04 - xxxxxxxxxx - lavc 60.39.100 - packet.h Add AV_PKT_DATA_AMBIENT_VIEWING_ENVIRONMENT. diff --git a/libavcodec/codec.h b/libavcodec/codec.h index 8034f1a53c..8bd678de7a 100644 --- a/libavcodec/codec.h +++ b/libavcodec/codec.h @@ -235,6 +235,12 @@ typedef struct AVCodec { * Array of supported channel layouts, terminated with a zeroed layout. */ const AVChannelLayout *ch_layouts; + + /** + * Array of supported YUV color formats.
