Test av_frame_side_data_desc and av_frame_side_data_name on
valid and invalid types, av_frame_side_data_get and its _c
variant for present and absent types,
av_frame_side_data_remove (including MULTI types with
duplicates), av_frame_side_data_remove_by_props filtering by
AV_SIDE_DATA_PROP_*, av_frame_side_data_clone with and without
AV_FRAME_SIDE_DATA_FLAG_REPLACE (including the AVERROR(EEXIST)
and AVERROR(EINVAL) paths) and with AV_FRAME_SIDE_DATA_FLAG_UNIQUE,
av_frame_side_data_add in move mode, with
AV_FRAME_SIDE_DATA_FLAG_NEW_REF and with
AV_FRAME_SIDE_DATA_FLAG_REPLACE over an existing entry, and
av_frame_side_data_free.
Coverage for libavutil/side_data.c: 72.14% -> 86.43%
Numbers measured against a full FATE run. Remaining uncovered
lines are internal allocation-failure error paths requiring
injected failures mid-operation.
