CroqueMr Lets just set a few things straight here:

1) You described this as a project you created, but neither of us is doing anything novel. We're both building on other people's research.
2) I did open PRs, as you suggested. You merged two, which I appreciate. The RC1 one is still pending, and fair enough on wanting regression testing there. FWIW my build tracks the latest LibreELEC main and playback has been solid so far, if that's useful data.
3) You said my build "directly overlaps with and interferes with" yours, but the reworked build you described hasn't been published. I can't coordinate around code I can't see. What specifically is it interfering with?

ht2tweak I have been testing with saving private ryan and 1917. I ordered an n150 mini pc so that I have hardware I can physically test on. I was getting frame drops on 1917 before (especially with the OSD up), but I no longer am with FEL offloaded to quicksync - but I am using a more powerful GPU than whats in the n150

CroqueMr I don't understand where you are coming from. You don't push commits to your repo, and I don't feel like waiting around for "next week" so I am just doing my own thing. Feel free to take or leave whatever you want from my builds - just as I have from yours. Its open source.

A new build to test.

libreelec-yblod

• CroqueMr's Intel Dolby Vision engine (CroqueMr/intel-dv-libreelec) : Standard (TV-led) Dolby Vision output from Kodi's own player, including Profile 7 FEL, on supported Intel GPUs.
• Video output calibrated to licensed Dolby hardware: IPT tunnel signal like Dolby players, a chroma siting fix, co-sited 4:2:2 packing and Gaussian chroma upsampling.
• Quick Sync enhancement-layer offload: Profile 7 FEL playback scales the enhancement layer on the Intel media engine (Quick Sync, via VA-API) instead of in shaders. On an i5-1135G7 this cut GPU render load during FEL playback from about 46% to about 12%, with no dropped frames, and the HDMI output stays within about one 12-bit code of the shader path. It is aimed at making FEL playable on smaller Intel GPUs. It can be switched off, and falls back to the shader path automatically when the media engine or driver can't do it.
• Seamless refresh rate changes (QMS-VRR): on TVs with HDMI 2.1 Quick Media Switching, a change between 24, 25, 30, 50 and 60 Hz (and 23.976, 29.97, 59.94) no longer blanks the screen.
• Dolby Vision menu (optional): the menu is sent in Dolby Vision too, so a Dolby Vision film starts without the TV switching picture format. With QMS, starting and stopping a Dolby Vision film causes no blackout at all.
• And more......

what TV are you using?

CroqueMr i forked tinyppi to work with libreelec - this may be useful for testing. it is in my repo.

just submitted a PR for a minor bug when starting DV playback of files that have an HDR fallback.

running this in a VM on an 11th gen nuc (NUC11PAHi5 M68302-400)

dv and audio passthrough both working.
