Test av_video_hint_alloc with 0, 1, and 4 rects, and
av_video_hint_create_side_data. Verifies that av_video_hint_rects
and av_video_hint_get_rect return pointers consistent with
rect_offset and rect_size, write/read-back of rect coordinates,
both hint type values, and OOM paths via av_max_alloc.
Coverage for libavutil/video_hint.c: 0.00% -> 82.05%
The remaining uncovered lines are the nb_rects overflow guard and
the av_buffer_create / av_frame_new_side_data_from_buf failure
cleanup paths, which av_max_alloc() cannot reach since it forces
the first allocation to fail.
Test all 5 public functions: av_mastering_display_metadata_alloc,
av_mastering_display_metadata_alloc_size, the create_side_data
variant, av_content_light_metadata_alloc, and its create_side_data
variant. Verifies the {0,1} rational defaults set by get_defaults(),
write/read-back of HDR metadata fields, frame side data attachment
for both mastering display and content light metadata, and OOM
paths via av_max_alloc.
Coverage for libavutil/mastering_display_metadata.c: 86.49% -> 100.00%
Test av_dovi_alloc, av_dovi_metadata_alloc, and av_dovi_find_level.
Verifies that the four inline offset-based accessors (get_header,
get_mapping, get_color, get_ext) return pointers consistent with
the offset fields, that find_level returns the first matching ext
block or NULL for a missing level, and OOM paths via av_max_alloc.
Coverage for libavutil/dovi_meta.c: 63.16% -> 100.00%
Test the five public functions not already covered by
tests/color_utils: av_csp_luma_coeffs_from_avcsp,
av_csp_primaries_desc_from_id, av_csp_primaries_id_from_desc,
av_csp_approximate_trc_gamma, and av_csp_approximate_eotf_gamma.
Iterates every AVCOL_SPC, AVCOL_PRI, and AVCOL_TRC value including
the extended ranges, round-trips primaries via desc_eq so the
canonical first-match (e.g. smpte170m for smpte240m) is accepted,
checks that a garbage desc returns AVCOL_PRI_UNSPECIFIED, and that
out-of-range enum values return NULL or 0.0 as documented. The
trc/eotf gamma values come from static lookup tables so the
floating point output is bitexact across platforms.
Coverage for libavutil/csp.c: 88.50% -> 94.46%
Test av_ambient_viewing_environment_alloc with and without the size
out-parameter, and av_ambient_viewing_environment_create_side_data.
Verifies the {0, 1} rational defaults set by get_defaults(),
write/read-back of the three AVRational fields, frame side data
attachment, and OOM paths via av_max_alloc.
Coverage for libavutil/ambient_viewing_environment.c: 60.00% -> 100.00%
Test av_ts_make_string with NOPTS, zero, positive, negative, and
INT64 boundary values, av_ts2str macro, av_ts_make_time_string2
with various timebases, and av_ts_make_time_string pointer
variant.
Coverage for libavutil/timestamp.c: 0.00% -> 100.00%
Test av_tdrdi_alloc with 1 and 3 displays, and the inline
av_tdrdi_get_display accessor. Verifies that the returned
pointer matches entries_offset + idx * entry_size, tests
write/read-back of display width exponent/mantissa and view ID
fields, and OOM paths via av_max_alloc.
Coverage for libavutil/tdrdi.c: 0.00% -> 100.00%
Test av_dynamic_hdr_vivid_alloc and
av_dynamic_hdr_vivid_create_side_data. Verifies zero defaults,
write/read-back of system_start_code, num_windows, and
color transform params (min/avg/var/max RGB), frame side
data attachment, and OOM paths via av_max_alloc.
Coverage for libavutil/hdr_dynamic_vivid_metadata.c: 0.00% -> 100.00%
Test av_buffer_alloc, av_buffer_allocz, av_buffer_create with
custom free callback, AV_BUFFER_FLAG_READONLY, av_buffer_ref,
av_buffer_is_writable, av_buffer_get_ref_count,
av_buffer_make_writable, av_buffer_realloc (including from NULL),
av_buffer_replace (including with NULL), av_buffer_pool
init/get/uninit cycle, av_buffer_pool_init2 with custom alloc
and pool_free callbacks, av_buffer_pool_buffer_get_opaque, and
OOM paths via av_max_alloc.
Coverage for libavutil/buffer.c: 0.00% -> 90.19%
Remaining uncovered lines are mutex init failures and
secondary allocation failure paths.
The drawvg filter can draw vector graphics on top of a video, using libcairo. It
is enabled if FFmpeg is configured with `--enable-cairo`.
The language for drawvg scripts is documented in `doc/drawvg-reference.texi`.
There are two new tests:
- `fate-filter-drawvg-interpreter` launch a script with most commands, and
verify which libcairo functions are executed.
- `fate-filter-drawvg-video` render a very simple image, just to verify that
libcairo is working as expected.

Add myself to JPEG XL and PNG decoders/encoders/parsers/etc. as a
suggested reviewer. I'm the maintainer of the JXL files and I know the
PNG code very well.
