Bug 2000024 [wpt PR 56017] - Fix mungeLevel function to zero-pad single-digit H.264 level hex values, a=testonly
Automatic update from web-platform-tests
Fix mungeLevel function to zero-pad single-digit H.264 level hex values (#56017)
The mungeLevel function is not zero-padding hex values, therefore breaking level encoding for H264 levels 1, 1.1, 1.2, and 1.3.
Without padding, single-digit hex values create invalid profile-level-id strings with only 5 total characters instead of 6.
The profile-level-id should have a size of 3 bytes.
For example, for level 1.0:
1 * 10 = 10, equal to hex 'a' which leads to 0x42e0a instead of 0x42e00a.
This patch ensures all hex values are zero-padded to 2-digits.
