commit c8ec660d783455807f3ad04cf78e94dde4d51ae2 Author: marcos ashton <[email protected]> AuthorDate: Wed Mar 25 23:10:45 2026 +0000 Commit: marcos ashton <[email protected]> CommitDate: Tue Mar 31 18:05:51 2026 +0100 tests/fate/libavutil: add FATE test for detection_bbox Unit test covering av_detection_bbox_alloc, av_get_detection_bbox, and av_detection_bbox_create_side_data. Tests allocation with 0, 1, and 4 bounding boxes, with and without size output. Verifies bbox getter indexing by writing and reading back coordinates, labels, and confidence values. Tests classify fields (labels and confidences), the header source field, and side data creation with frame attachment. Coverage for libavutil/detection_bbox.c: 0.00% -> 86.67% (remaining uncovered lines are OOM error paths) Signed-off-by: marcos ashton <[email protected]> --- libavutil/Makefile | 1 + libavutil/tests/detection_bbox.c | 132 +++++++++++++++++++++++++++++++++++++++ tests/fate/libavutil.mak | 4 ++ tests/ref/fate/detection_bbox | 22 +++++++ 4 files changed, 159 insertions(+) diff --git a/libavutil/Makefile b/libavutil/Makefile index 1095c5cfcf..4630e51bbc 100644 --- a/libavutil/Makefile +++ b/libavutil/Makefile @@ -270,6 +270,7 @@ TESTPROGS = adler32 \ cpu \ crc \ des \ + detection_bbox \ dict \ display \ encryption_info \ diff --git a/libavutil/tests/detection_bbox.c b/libavutil/tests/detection_bbox.c new file mode 100644 index 0000000000..330ed3b7b0 --- /dev/null +++ b/libavutil/tests/detection_bbox.c @@ -0,0 +1,132 @@ +/* + * This file is part of FFmpeg. + * + * FFmpeg is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * FFmpeg is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
