Dolby Vision now possible through MP4 Mux.

EDIT:

I really hope somebody can answer this.

Does the Plex app for Shield support DV from MKV containers?
If yes, which profiles?

And what about the LG WebOS Plex app?
I believe it only supports DV profile 5 (MEL) from MKV containers right?
What about .TS containers?

I'm looking to store my videos in a container which can also carry lossless audio, but is capable of triggering DV on both LG TVs and the Shield using Plex.

I know LG only supports AC3, but that's no problem because I can just store the TrueHD track as the second one.

The BL.hevc seems to be the HDR part, is that right?

Yes, the BL.hevc file does not contain any Dolby Vision data, but it does still fallback to HDR10+.

Hi! I am newbee here so please bear with me. I've experimented with dovi_tool a little bit but failed every time. Obviously I am doing something wrong so I would appreciate your help. Thank you.

Here are my exact steps (using Windows 10 Pro 64bit and everything like source files and dovi_tool.exe/ffmpeg.exe are inside main folder):

01, ffmpeg -i DV_WEB-DL.mp4 -c:v copy -vbsf hevc_mp4toannexb -f hevc - | dovi_tool -m 3 extract-rpu -
02, ffmpeg -i HDR.mkv -c:v copy hdr.hevc
03, dovi_tool inject-rpu -i hdr.hevc --rpu-in RPU.bin -o output.hevc
04, final output.hevc is muxed in latest MKVToolnix with sound and subtitles from HDR.mkv

There is a difference between DV web-dl and remux HDR10 file in frames but if I understood correctly, dovi_tool should adjust it automatically for metadata. Am I right? Using the latest 0.5 version.

I do not have any errors either in ffmpeg or dovi_tool. All is going smooth. Except when I try to play the final file in either mpv or mpc-hc I see glitches - for example in the beginning when the the logo appears, the picture will freeze for a couple of seconds and the sound is continuing. At that time the glitch in small rectangle in left upper corner will appear. Here are examples:

Just got a Zidoo z9x player.. works great for any file I played but tv-led has the wrong bt2020 flag as well SMH

The x700, the Shield, the appleTV, the firestick, Chromecast, Ugoos:



colors are mostly accurate, still have to check DV but at least there is no red push on Doctor Sleep. if they fix the bt2020 flag, it is a better device than the Shield IMO

HDR10 422 12bit

damn with all the players you've bought recently, you should've just bit the bullet and gotten one of the oppo clones

[RESET_9999]

yeah but just like the x700, the oppo cant play cropped DV properly. with all the appletv and amazon(hdr10+ to DV) content , it was a problem.

And now I can watch all the mel DV content via my network and only use my hdd /x700 for FEL. It's much more practical now. plus I get to reduce the amount of TS files in my library ( i prefer all MKV)
zidoo works surprisingly well, literally played every single file I tried.

Hi, have you installed latest firmware?
On your test pic it shows the BT2020 pic with 25hz, did you try 23hz?
Post in the Zidoo forum, Mark Swift has a Vertex2, if it is a bug he will get it fixed.
I’m mostly pleased with my Z9X after the latest firmware updates, it was a bit buggy for a long time after release.

Hi,
yep, it's the first thing I did. I updated to the latest firmware via the settings. Is there a BETA firmware that I need to install manually?
Yes I tried many different files (23 /24hz), all the same. You can see the flag as well when you press ''OK'', the zidoo info menu shows RGB bt2020 signal.

I posted my finding on the zidoo forum thanks

Also, I personally don't care about this because I will use it for DV only but I noticed a severe black crush in HDR10/SDR using the Spears and Munsil black level pattern.

I do not have any errors either in ffmpeg or dovi_tool. All is going smooth. Except when I try to play the final file in either mpv or mpc-hc I see glitches - for example in the beginning when the the logo appears, the picture will freeze for a couple of seconds and the sound is continuing. At that time the glitch in small rectangle in left upper corner will appear. Here are examples:

Have you tried using mkvextract instead of ffmpeg for the HDR10 base layer demux?
If there are issues with the injected file, they are probably present in the original demuxed bitstream.

What is cropped dolby vision? Which movies have it? When you say the x700 can't play those cropped dv movies properly, you mean it won't play at all or there are some problems during playback?

Brilliant. It seems to be working fine using mkvextract. Will test the result later but no glitches at all. Thanks so much, kind sir, for all the work you are doing.

When the video is encoded without black bars (E.G. 3840x1600pixels). Bluray players expect black bars and when there isn't, the black bars appear grey. All the AppleTV and Amazon content is cropped.

There is a difference between DV web-dl and remux HDR10 file in frames but if I understood correctly, dovi_tool should adjust it automatically for metadata. Am I right? Using the latest 0.5 version.

no.
this is true for the frame count but you still have to make the RPU start at exactly the same frame as the remux. I did every single bluray remux that didnt have DV and i think only 3 times, it didn't need frames adjustments with a JSON edit.

What movie is that ? i certainly did it and never experienced the glitches. I use tsMuxer for extracting.

EDIT:

does the Plex app for Shield support DV from MKV containers?
If yes, which profiles?

all of them as long as the file are remuxed into a single track format.

I'm looking to store my videos in a container which can also carry lossless audio, but is capable of triggering DV on both LG TVs and the Shield using Plex.

I know LG only supports AC3, but that's no problem because I can just store the TrueHD track as the second one.

tsmuxer it is then...
they will play in DV+lossless audio on the shield and in DV on your TV.

Cruella. Oh, I thought it is automatic now. So how exactly do you achieve that the RPU starts at exact frame as the remux?

I tried Soul 2020 too and I have seen your post in this thread. I had this warning in dovi_tool:

Code: Select all

n:\dovi_tool>dovi_tool inject-rpu -i hdr.hevc --rpu-in RPU.bin -o output.hevc
Parsing RPU file...
Processing input video for frame order info...

Warning: mismatched lengths. video 144645, RPU 144685
Metadata will be skipped at the end to match video length

Computing frame indices..
Rewriting file with interleaved RPU NALs..

Does this mean I have to adjust it via JSON edit as you did?

I had no warning in dovi_tool for Cruella though.

Now I am a little bit lost =(

[quietvoid]

You have to compare both versions frame by frame to determine if and how they have to be synced..
For Soul, see the posts here: viewtopic.php?p=111007#p111007
