10.2.3 Media Profile: CMAF HEVC HHD10 ('chh1') The details for this profile will be added to an updated version of the specification after a questionnaire to the media profile proponents.
I added the HEVC Test Content Options to an updated dpctf specification here
In order for better tracking, I also provided the content options for each of the profiles here:
I've tried to make the same style of sparse matrix for HEVC as for AVC following the list of content options. The results are somewhat different from the proposal at the end of the document from @haudiobe .

The biggest difference from AVC is that the limited number of resolutions tested. For AVC, we did a good set of resolutions covering many (most) of those that might get used in a ladder. The original proposal here was just 4 combinations, 1280p50/60, 1280p25/30, 720p50/60 and 720p25/30. For avc, we had 15. I've only put 4 in this google doc.
DPCTF Call:
I have 2 changes to propose, unless there is a particular reason these tests are relevant for AVC but not for HEVC. This relates to the discussion about consistency in test content across different codecs.
We should include 1 test stream with Picture timing SEI present (pic_struct=0). While this is optional and all content is progressive, the presence of this SEI should be tested as it is for AVC.
In order to test the presence of constant vui_time_scale and vui_num_units_in_tick, at least 1 test stream including VUI timing information should be created.
