Sure. We can wait a day or two for more feedback then push the first patch.

Could this get committed without fate test first, and we can discuss later if they are really required? (Assuming there is no "parsing" involved, just a new UL which reminds me you could remove the word parser from the commit message.)

Got any idea what other ULs there are for this? If not then you should
probably be more strict and pick a matching length of 16 instead of 14.
Especially since you say there is no speficiation for it yet.

[FFmpeg-devel] [PATCH]lavf/mxfdec: Allow MXF parser to identify the Canon XF-HEVC codec/format for video essence
Hello ffmpeg-devel:
Attached is a patch to allow the MXF parser to identify the Canon
XF-HEVC codec for video essence.
This codec/containerization is found in the Canon XF-705 camera that
Canon released in 2018. The camera can encode video using HEVC at
either a 110 or 160 Mbps bitrate, and the video is 3840x2160, YCC 4:2:2
at 10-bit depth (at a variety of choosable framerates).
At the moment there is little information published about the
containerization of the video, and I am not aware of it being a SMPTE
standard or otherwise. However, by identifying the video as
AV_CODEC_ID_HEVC by way of its universal label (UL), ffmpeg can make use
of the video. Bitrate, resolution, color space, framerate, and bit
depth all seem to be correctly identified.
Sample MXF files, as well as their successful conversion thru a patched
ffmpeg, are available at
http://www.matthewmckenna.com/contrib/ffmpeg/xf-hevc
Thanks.
