# Test that compares the structure (boxes) of AVIF files metadata, dumped as xml,
# with golden files stored in tests/data/goldens/.
# Depends on the command line tool MP4Box.
#
# Usage:
# test_cmd_enc_boxes_golden.sh <avifenc_dir> <mp4box_dir> <testdata_dir>
#                              <test_output_dir>
# But most of the time you will be running this test with 'make test' or
# 'ctest -V -R test_cmd_enc_boxes_golden'
