"Peacock Green Bug" - H265 shows display with green tint when SDR/HDR ---> DV

[andyxo-xo]

cpm, you asked me to put this in a fresh post :-)

@cpm-code & @avdvplus, thanks so much for your continued work building great software for our AM6b+ 's :-) Sorry to bring this up in this long post but since you are so involved with providing the best "playback" experience I am hoping now would be the time to bring up the "Peacock Green Bug" found in cpm builds as discussed in the Discord for #ugoos-media player. Am hoping that if you can find the time you could test one or more of the following small files (which are four completely different Peacock TV shows) in your new builds to see if the bug has been rectified or still there. All four sample files display in odd green tint for us when displaying in DV....

Short bug background: This bug involves the VS10 engine "on-the-fly" displaying SDR & HDR formats ---> DV that come from the streaming network Peacock (and oddly only Peacock) that are encoded in H265. They exhibit in green colors using pm4k and just a blank screen when using the internal CE player with the cpm SDR8/10 & HDR ---> DV conversion settings set to on, and it doesn't matter if display-led or TV-led. This bug has been verified on the Discord by multiple users so not just me. Apologies in advance if this is something you guys are not interested in fixing but I just wanted to bring it to you fellas' attention that is does exist.

Note : Last month I had been asked to post about this bug but I didn't because I didn't think development would be continuing. But now that it is I humbly ask if you could check it out please. Other short samples can be provided. Thank you kindly :-)

Believe the HEVC has a atsc nalu which the amlogic kernel thinks is atsc-DV and clashes with VS10, file it self is not seen as DV as does not have the other DV markers (is not in fact DV and the atsc nalu is for something else, this is a mistake by the kernel) - will check one of the files in due course to see if my assumption is correct

[cpm-code]

Downloaded and played the first file, plays fine with VS10, as expected it is the atsc in the DV, if technical can use the sysfs to switch off atsc support in the dolby vision module (the dovi.ko used does not support it anyway).
If / When do another public release then will be included
