Hello, I truly apologize if this has been asked/answered before - Does JRiver 32 support the processing of the FEL layer on MKV Dolby Vision files? Not just the support of RPU, but the added bits/resolution which FEL brings to the table.

No.

Might be a long time till you see this in MC. It's only *just* become possible for average joes to get working on some specific Amlogic based STBs. x86 / regular GPU support doesn't exist right now at least as far as I can tell.
I've got one on the way to play with, I'm excited to poke around and see how it's being accomplished in more detail. I don't think what they've gotten working will translate but who knows?

There is DoviBaker - where you merge the FEL information into the base layer, making all FEL improvements available to solutions like JRVR, MadVR, MPV, etc. However, DoViBaker is not a runtime solution, and requires re-encode of the base HDR file. Which, if not done correctly, could also lead to a downgrade in image quality.

I would love to see a proper, runtime FEL solution available as well. It's the last frontier that is missing in my opinion. And while not all titles are impacted by FEL, we do see titles poping up here and there where the FEL layer comes to rescue the poor HDR layer encoding. The last one is Once Upon a Time in the West... Macroblocking and other issues with the base layer ,improved on FEL.

I picked up one of the Amlogic devices. If you want "real time" support without having to remux as you said, a device currently has to have a Dolby "blob" capable of using FEL. The only device I could find that offered the support was the Ugoos AM6b and Ugoos AM6b+ devices. Sadly, they are Android devices, not Android TV so mostly unusable on a TV while in Android mode. Might be a way to run Android TV on top of that but not sure it's worth the effort since you would have to boot into Coreelec to use DV videos and back to Android TV if you want the AnTV interface for other stuff on the same box. On the plus, the AM6b+ reboots quickly.

In order to get the FEL to play you have to be using Coreelec (which is good as it boots instead of Android) and playback with supported rips; they seem to work fine via Kodi playback and also works w/ the Plex plug in Plex 4 Kodi. MKVs work perfectly for this if they are ripped w/ the DV layer intact (MakeMKV does this by default).

This only works on these devices because they use Amlogic S922X-J SoC which was, apparently, improperly allowed to use the BD player DV blob in it's SoC implementation. This is the same blob on UHD players that support DV.

I am not sure that MC will ever implement DV FEL playback but might be able to be designed in a way to feed the FEL into JRVR to enhance its capabilities?

FYI, The second generation of the Fire TV Cube is also capable of FEL if using with CoreELEC (same Amlogic chipset), but the firmware needs to be an older one.

Ideally, using a capture card (like BlackMagic DeckLink Quad HDMI) would in theory allow the FEL output oof such devices added to JRVR tone mapping. Have anyone trying that yet? It works very well with MadVR and VideoProcessor, but you get stuck with an older release and outdated tone mapping features.
