Thanks.
One last question, if you saw Doctor Sleep , did you also encountered the problem of the girl's cheeks (as reported HERE) with your setup and your files?

I have that movie with re-encoded BL too (I encoded it with hdr10+ parser so only the bitrate is different once again) and I checked it again: the girl has blushed cheeks, but it seems natural to my eyes almost the same as on my HDR10 monitor and nothing like on the Shield/Plex pictures posted in your link.

Yeah that red push issue seems to be one isolated with the Shield. You wouldn’t happen to have one also would you? It’d be great to have some comparisons between the Shield and m9072 for playback of movies with an FEL.

I was growing tired of copying everything to my USB drive. For all my Roku peeps, after ~8 hours (in addition to the already countless) spent tinkering with this horrid format that I can't seem to get away from, I finally figured out a way to stream DV files with subtitles to a Roku Home Theater Dolby Vision TV via DLNA. Plex wasn't able to do it, Windows Media Streaming couldn't do it, only Serviio could. Note that you'll need to use Profile 4 files for this. Quantitatively and qualitatively, there is no real detriment to having Profile 4 files over 5 in my experience. I usually encode everything in Profile 5 simply because the number is higher, but the only difference in reality is that 5 uses a PQ algorithm to recreate the DV colorspace while 4 has an explicit EL. However, 5 can support a theoretically higher bitrate by way of having a higher DV level (which is distinct from profile!), though I've never seen a file as of yet that exceeds 4 or 5's level capabilities. Well, this is a tangent. Anyway, to stream DV files with subtitles on a Roku DV TV-use Serviio, put the .srt with the mp4, and press play.

eeek don't do something simply because a number is higher. like you said, profile 5 cannot utilize an explicit EL, so there will be issues with FEL movies as a proper FEL->MEL conversion does not currently exist.

No, unfortunately I don't have a Shield.

Is there anyway to use handbrake to compress the base file before using your special tool?

For this type of experiment, I recommend using the 0.0.4 alfa version of my tool.

You're right when you say "it's the EL where all the DV info lives" but keep in mind that the info contained in EL are "calibrated" on those inside BL.
If you re-encode BL, logically, you should also modify EL.
No one has yet reversed the algorithm needed to generate new RPU metadata (and, in the case of FEL layers, new frames).

Imagine a guy (BL layer) with a weight of 180Kg who, after following a diet, reaches a body weight of 80Kg.
His clothes (EL layer) are now unusable but the clothing stores (the algorithm) are closed due to the quarantine.
The guy will be forced to use his old clothes.
He will always have clothes on but his style will be a little "sui generis".

Hey yusesope, thanks so much for the quick response. really appreciate the help. I will try using the latest alfa version of the tool and report back.

Anyway, thank you again for all the hard work you've put in to the tool... it's freakin awesome.

stephon1024, did you give my test samples a try? Did they work? It would be nice to get a little feedback.

It was a joke.

I've experimented a lot, re-encoding the BL layer with staxrip/x265 and 0.0.4alfa always merged it with EL without any problem. Also I have an m9702 so I can just mux the re-encoded BL and EL into full UHD BDVM structure (with tsMuxeR) and DV works. I spent hours by testing the results (re-encoded BL+EL), comparing them scene by scene to the HDR10 base layer and also to the full untouched UHD BluRay on my LG C8 Oled and I really beleive this method works perfectly. I've never noticed any difference between the files with re-encoded BL and the full UHD BluRays, but the differences were pretty significant comparing them to the untouched HDR10-base layer. I used the following movies for my tests: Aquaman, The Meg, Fantastic Beasts 2, Midway, Game of Thrones S08E03.
Using the right x265 settings, only the bitrate will be lower but everything else (including the HDR10 metadata) will be the same as in the original BL so I don't see why wouldn't it work.

PapitaHD - appreciate the feedback. I'm going to grab staxrip and see what I can do. Anything I should know about what x265 settings to use when doing this?

Thanks,

Hey Marty,

Yes sir, I tried both of your samples... So the DV profile 7 sample didn't work at all off the USB with a hard drive on my c9.

The profile 6 one just kept trying to do load and nothing... I think the best profile for direct play off an LG TV is DV profile 4. That works for the bluray rips too because it supports the 1:1/4 BL/EL ratio that comes on UHD bluray's with DV.

I'm able to get profile 04.06 DV files to play... again, the bitrate is just too high for the C9 SOC, so I'm trying to figure out a way to compress the BL without breaking the DV. Looks like I've got some good feedback - I'll report on this thread if I'm able to get it to work.

I'll also report on my full workflow (all software involved from backup using MKV to final output/playback).

Thanks for your help tho Marty, always worth a shot!

Profile 04.06 seems the best for the players I have access to. All the discs I've ripped with that so far work great.

You should always use crf, and also check the following settings in the x265 options menu of staxrip:
Vui page: HDR10 - yes; Block-level luma and chroma QP optimization for HDR10 content - check this box
Slice Decision page: Open gop - uncheck (no open-GOP); min GOP size 1, Max GOP size 24

Are there any differences in quality of the dv profiles? e.g. dvhe06.06 vs dvhe08.06. If yes the which is the best?

Hi stephon1024,

Here are a couple more samples for you to try. They are all profile 4.

MP4 sample: https://www.mediafire.com/file/yd16poxk ... 9.zip/file

TS sample 1: https://www.mediafire.com/file/dyud6pxl ... 9.zip/file

TS sample 2: https://www.mediafire.com/file/flnswvgk ... 4.zip/file


Let me know how you go...
