Dolby Vision now possible through MP4 Mux.

[RESET_9999]

Thank you, i wasnt sure if it would thats why i asked.
What is the player-led bug? Havent been keeping up with DV in a while

From what i can gather from reading just the last pages, it seems Zidoo Z9X / Dune HD Real Vision 4K is the way to go for profile 7 mkv playback?
Or Sony x800m2 for mp4 i guess?

I’m looking at getting the Sony X800m2. Before I do I’d like to see if Dolby Vision Fel is worth it. Does anyone have a list of films where the Fel is a reasonable size?

For those interested in DGDemux: The writer of the tool created a utility to merge the gap-processed demuxed, separate TrueHD and embedded AC3 tracks back together into TrueHD+AC3.

http://rationalqm.us/board/viewtopic.ph ... 406#p15406

I tested this new tool and it worked very well and this is exactly the solution I was looking for the other day: a way to merge thd with ac3 without encoding the core in eac3to.
Took about 3min for a 2h movie when eac3to usually takes more than 10minutes.(more if clipping detected).
Obviously, you have to demux the mkv first(and ac3 track must be present) but it still faster thanks to my NVME drive (+ most of the time i have to demux the hevc too anyway)
The fact that it can fix the gap from makemkv files is great as well.

I hope it plays well on the x800m2...

the latest beta without time limitation: 113B or 114 if I recall correctly.

I've just installed my PC with windows 11 but still can't see D3D11 Native from your tool.

i dont know, works fine here.. are you sure lavfilters is set to native?

Hi i have something to share

I am owner of LG CX and C8 models and also nvidia shield.
I made numerous conversions to make sure what is best, i found that for those LG models most reliable is mp4, m2ts is somewhat ok but for me had seeking issues at least with emby. I have found its best to convert to proper mp4 and keep Atmos and other tracks for safekeeping to be able to remux to mkv in future once at least nvidia shield plays correctly (it does not due to colors issues etc). I have found for best results is to play mp4 directly on Emby app on LG

I have created bash script that automates authoring and conversion of different Dolby Vision mkvs to mp4 that will work on above LG models without issues, so far i have converted around 30 releases no issues to the point i automated workflow

So my tool converts whatever mkv you throw at it to mp4 with DV4,5 or 8 with EAC3 audio and keeps original truehd atmos etc alongside for future, i have tested and remuxing with mkvtoolnix makes it playable with atmos again on nvidia shield no issues.

It automates ffmpeg dovi_tool and mp4box workflow and try to use as little drive space as possible thanks to linux pipes. I have it running on my NAS and is chugging along fine

My latest report on the X800M2:
- Choppy playback issues seem to be resolved after stabilising my network (replaced switches and reserved an access point, disabled modern standby). Also I need to make sure there's nothing else gobbling up IO on the hard drives from which im playing movies, obviously.
- I still have it lock up sometimes after pause, stop, resume kind of situations, which means I need to do a hard reboot of the player
- Even for non disc content, it appears you need to manually change between dolby vision on and off for non-dolby vision content. my HDR content otherwise has raised black levels. I tried forcing color spaces, change my tv edid to LLDV or RGB (just to see if it somehow would treat HDR content better by miracle), but no.
- Connected to my VRRoom switch/splitter, I sometimes need to switch ports back and forth because of otherwise black screen. but this is probably the VRRoom firmware.
- As I find the remote (limited cec) and the navigation in general sub-par, I repurposed a DLNA music cast plugin for Plex, to cast videos to the X800M2 directly from the plex app on phone and tablet, basically fixing my biggest usability concern.
- Seeking via cast can drop dolby vision back to hdr, have to stop and start to get it back

Im a little sad about the manual DV switch, but I guess if it really bothers me I could buy a second unit and configure it with it off, then I just need to pick the right cast target based on HDR/DV

My M9203 arrived but has weird artefacts and color issues so probably has to go back.
I also noticed the DV in TS problem where you have to view another test file (thanks RESET9999) to fix it.
So in the end, it's tradeoffs everywhere

Can you explain how you did this cast from phone?
Thanks

I found a python project that supports casting plex music to DLNA servers, and repurposed it for my video needs.
It's a little rough edges right now, but I may publish it in the near future, if there's interest.

thanks. too difficult for me.

I've had an issue like that where I get the 'no signal' message on my TV when turning on the player. It was usually fixed by turning the TV off and on again. My player is connected directly to the (LG) TV so it's definitely not something that only happens with switches.

Im a little sad about the manual DV switch, but I guess if it really bothers me I could buy a second unit and configure it with it off, then I just need to pick the right cast target based on HDR/DV

My setup is to use the Sony just for DV rips, and to use another box for HDR10 stuff and streaming (I use an Apple TV 4K, but I expect that any of the other good mainstream streaming boxes would work nicely since it seems to be a lot easier to get HDR10 playback right compared with DV).

Thanks for posting your impressions, and I'm glad things are mostly working for you too. For my part, now that I'm feeding the X800M2 files that aren't broken, it's handled every movie I've tried fine. But I have only been testing titles out for ~20 mins or so and shamefully haven't found time to watch a whole movie yet.

Ah damn.. I bound the vrooms hot plug command to HomeKit and Siri, so I can recover without TV restart atm.

Me too, but no HD audio passthrough (Atmos). I also have a Shield pro but im trying to sell it to consolidate and also because of the various color issues even in non DV (if I got it right).
Hence the Oppo 203 clones seemed so appealing to me, as it seemed to tick all boxes, minus the "mkv; to AC3 and back to truehd again" and "run the fix.ts after watching DV ts files" hassles.

It's been great so far indeed. I'm testing it and up til now it has stood up to the promise. Yeah, it's a two way process but I don't mind as I usually do a lot of steps manually. Combined with DGDemux it's the perfect toolset for gap processed demuxing and remuxing with the native Dolby AC3 track. This guy makes great software.

Could you please let us know how it plays on your X800M2? I haven't decided yet on purchase.

Thanks for the script!

yes, it works, and no problem with the 10min I tested.

from the author of the tool:

Glad you find it useful and thank you for your testing. I will release it formally with source code tomorrow. There will be an option to choose what to do if the two audio streams are not the same duration: truncate the longer one or do not truncate it.

I guess we could encode a 4h silent ac3 core and use it for any movie (in case the mkv doesnt have an AC3 compatibility track)
