Dolby Vision now possible through MP4 Mux.

Hey guys, a question about getting DV FEL to work on the Google CC TV 4K.

Yesterday after reading through this topic a bit I decided to try playing FEL files on my CC4K in Plex and had succes. I played RESET_9999's FEL test video ''This Device can Play DV FEL'' and it worked. Today I wanted to show my friend that it works who has a similair setup and it didn't work anymore.

Are you guys aware of any updates done to plex or android that makes the Chromecast TV 4K not play FEL in plex? It's very weird how in the timespan of 1-2 days it stopped working all of a sudden. Now when I try to play it, plex reverts to HDR10 and the screen is red with no text even though I did nothing to change it.

update 2 hours later: Me and my friend have been trying to get this to work without succes. When we have go to video settings on the CC4K and have 'match content' on, every FEL DV content falls back to HDR10. When we both have 'Dolby Vision Alwas On' set on it 'seemingly' works but doesn't. We get a red screen with no text. This leads me to believe that it is playing it in 'MEL-mode' so to say even though.

Another thing to add is that we got it to work in kodinerds v22.0. The test clip with the text works perfectly, but RESET_9999's other 2 ST DL DV FEL test videos, namely Halloween II and Minions Rise of Gru stutters/freezes and does not play fine (does appear to stay in DV picture preset and does not revert to HDR10).
I however have a mkv remux of ALIENS that I have confirmed as DV FEL (ST-DL, BL+EL+RPU Dolby Vision Profile 7) which plays fine in Kodinerds v22.

Very confused and ask you guys for help on the matter. Thanks!

I have a LG G3 and my friend has a SONY XG950. Both own a Google Chromecast TV 4K with the lastest version of Plex and Kodiners (22.0).

Go into the Plex settings and make sure that ''force profile 7'' is enabled.

The Chromecast seems to have some EL/BL sync issues though. Check out this test file, there's is an encoding bug/artifacts in the HDR10 BL that FEL can fix but it doesn't work on the Chromecast. I also tried to let play Power Rangers till the end the indeed the ending credits text was white but looked slightly out of sync compared to my x800m2 and Ugoos.

EDIT: about the stuttering, try switching off the HW overlay in the developer settings

Bro, mad thanks man! It now works! I have NO IDEA why that settings magically turned itself off in Plex as I'm 100% sure I didn't turn it off myself.

Also tried to set HW overlay to off (which I have to turn on disable HW overlay ironically) but it didn't help the Kodi stuttering. But to be fair, I don't care about that anymore since the only reason I installed Kodinerds in the first place was because it wasn't working in Plex anymore. Now that it works in Plex I don't need to have it be working in Kodi too but thanks for the tip anyway!

On my end, GTV PLEX is unwatchable when ''HW overlay'' is not disabled. Micro stuttering every 30 seconds or so.

I'm the friend sultanmehmet is talking about. Plex seems to "work" now except for the continious buffering I get with FEL DV movies (MEL seems to play fine, even with similiar file sizes and bitrates) however, I'm more interested in getting FEL to work with Kodi, disabling the hardware overlay doesn't seem to fix the issue for me. Any other suggestions ? Thanks in advance

Can DL-DV added with a software update in the future on the ugoos (coreelec)? Or is the hardware of ugoos limited to support this?

[RESET_9999]

it already supports dual-layer DV...

I believe the issue there is that Kodi simply can't handle multiple track playback. This is also why it can't play DV from a UHD ISO - it will only play the first track and fallback to HDR10. Doesn't sound like there's a lot the CoreELEC devs can do about that until support for playing multiple tracks is added to Kodi upstream.

Sorry, i mean DT-DV.

[RESET_9999]

it's a kodi limitation and there's no point using DT-DL mp4/ts/m2ts on this device. MKV is a much better container.

[sultanmehmet]

I now have a couple of FEL P7 DT DV movies that I want to convert to FEL P7 ST in order to play them in Plex. I use macOS myself, is there a handy tool to convert/mux DT to ST? I heard RESET saying that it's now possible to do in MKVtoolnix, but I don't really know how to use that tool.

I also downloaded dovi_tool 2.2.1 for macOS but it opened a command line where I didn't quite understand what to do.

I can use windows if need be.

It only works with DT-DL TS/M2TS rip. If it's an MP4, for some reason mkvtoolnix keeps it DT-DL.

So for m2ts/ts file, just remux it in mkvtoolnix.
For MP4, I guess you have to remux it to TS and then to MKV.

both tsmuxer and mkvtoolnix are available on mac

@Reset9999, got any suggestions to get FEL MKV's to work propperly with Kodi?

[kazuma]

Is the ugoos powerful enough to run a 5TB external usb hdd via usb-ports? Or do you need a usb-hub with power adapter?

I don't know about Kodi but it plays fines in PLEX on my end(except for the slight BL_EL OOS)
