CE-NG Dolby Vision (+FEL) for DV-licensed SOCs (s905x2, s922x/z, s905x4)

FYI, I spent a few hours looking before, I could get it decoding without interlace but some frame rate issue, I think it is using a different path to other HW decoders (older approach) need an expert.

VC-1 Side Note:

• I had partial success on getting VC-1 24fps 1080p using AML HW decoding working correctly. - By removing “deinterlace” from the vmap used.
• Under the hood the HW decoder was always correctly decoding as progressive, but output only half the image with “deinterlace” in the vmap.
• But this resulted in a 10fps frame rate drop though so to not useful at this point, something else not right.
• Oddly putting into 50 or 60 hz improves things but still not correct, nothing on the system looks strained, and no frames are skipped it just runs slow in 24 hz.
