avutil/frame: add av_frame_side_data_remove_by_props() As discussed in the previous commit, we often need a convenient way of stripping all side data related to a certain aspect of the frame. This helper accomplishes just that. I considered also adding a way to match only side data matching *all* properties, but I think this is sufficiently useless in practise to not warrant inclusion in the API. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=b88944a8aa599be0f16603380e7bc51402d3caf8 --- doc/APIchanges | 3 +++ libavutil/frame.c | 16 ++++++++++++++++ libavutil/frame.h | 8 ++++++++ libavutil/version.h | 2 +- 4 files changed, 28 insertions(+), 1 deletion(-) diff --git a/doc/APIchanges b/doc/APIchanges index f6c4b6797e..4fa4db142f 100644 --- a/doc/APIchanges +++ b/doc/APIchanges @@ -2,6 +2,9 @@ The last version increases of all libraries were on 2024-03-07 API changes, most recent first: +2024-12-xx - xxxxxxxxxx - lavu 59.53.100 - frame.h + Add av_frame_side_data_remove_by_props(). + 2024-12-xx - xxxxxxxxxx - lavu 59.52.100 - frame.h Add AV_SIDE_DATA_PROP_SIZE_DEPENDENT and AV_FRAME_DATA_PROP_COLOR_DEPENDENT. diff --git a/libavutil/frame.c b/libavutil/frame.c index 1dced3b52b..342079b5a1 100644 --- a/libavutil/frame.c +++ b/libavutil/frame.c @@ -961,6 +961,22 @@ void av_frame_side_data_remove(AVFrameSideData ***sd, int *nb_sd, remove_side_data(sd, nb_sd, type); } +void av_frame_side_data_remove_by_props(AVFrameSideData ***sd, int *nb_sd, + int props) +{ + for (int i = *nb_sd - 1; i >= 0; i--) { + AVFrameSideData *entry = ((*sd)[i]); + const AVSideDataDescriptor *desc = av_frame_side_data_desc(entry->type); + if (!desc || !(desc->props & props)) + continue; + + free_side_data(&entry); + + ((*sd)[i]) = ((*sd)[*nb_sd - 1]); + (*nb_sd)--; + } +} + AVFrameSideData *av_frame_get_side_data(const AVFrame *frame, enum AVFrameSideDataType type) { diff --git a/libavutil/frame.h b/libavutil/frame.h index 8345010e22..929dbb885e 100644 --- a/libavutil/frame.h +++ b/libavutil/frame.h @@ -1183,6 +1183,14 @@ const AVFrameSideData *av_frame_side_data_get(AVFrameSideData * const *sd, */ void av_frame_side_data_remove(AVFrameSideData ***sd, int *nb_sd, enum AVFrameSideDataType type); + +/** + * Remove and free all side data instances that match any of the given + * side data properties.
