In my limited experience (so far) with all this, I have found that the ONLY DV file format that will play on my LG 4K TV is either .ts, or .m2ts !!!!

Neither .mp4 or .mkv will play as DV, only as HDR10.

The only playback issue I have is if I "bump" the playback forward or backwards by the default 15 sec's, it will stall the playback for a second or 2, other than that, it's fine.

I've only made a few tests so far, but it seems Profile 8 are indeed not detected as DV once converted with DDVT_MKVTOMP4.

Yes, I'm running the docker setup in Linux. You could maybe try WSL.

Again, I can only concur to this. The "Awaken Girl" MKV sample converted with DDVT_MKVTOMP4 successfully plays as DV. And it is Profile 7.

Like I stated in my previous post, the converted "Awaken Girl " sample plays fine as DV although the codec is hev1 for reasons...

Yes, I noticed that as well. Weird.

That was also my first assumption, but considering the other MKV samples I have converted, I'm having second thoughts.

That LG player is a mess.
It's a pity I don't have more MKV samples (with different profiles, ...) to play with.

EDIT: I've managed to get my hands on another very large Profile 8 (dvhe.08.06) DV MKV file. Once again, converted to mp4 with DDVT is not detected as DV by LG TV, while it is with dvmkv2mp4. So under *some* circumstances, profile 8 can actually play as DV on the LG (2018).

What Dolby Vision profiles do media streaming services use?

[GodzilaAvenger]

5, sometimes 8. Blu-rays use 7.

Thanks

No DV as has been said, but there was talk last year of Google pushing for a new open, royalty-free HDR & object-based audio formats.

@-QfG- I'm using v0.58 and I noticed that when using the injector script, instead of creating a "_[TEMP]" folder in the directory where the ".mkv" file is, the script creates a "SAME AS SOURCE" folder in the "DDVT" directory and stores the files there. Could you look into this and see if there's a bug somewhere?

Also, it would be great if when entering ALL in the FRAMEINFO tool, the L1 plot that dovi_tool can create is also generated.

UPDATE. Changing lines 87 and 88 to

if "!TMP_FOLDER!"=="SAME AS SOURCE" set "TMP_FOLDER=%~dpn1_[TEMP]"
if "!TARGET_FOLDER!"=="SAME AS SOURCE\%~n1_[INJECTED]" set "TARGET_FOLDER=%~dpn1_[INJECTED]"

(same as the demuxer script) seems to resolve the issue.

Good afternoon, thank you very much for the great tool you have created.

[fransalas]

good afternoon, maybe my question is somewhat risky but there I throw it, there would be a possibility of incorporating a script that transforms the RPU to XML and vice versa? thank you again

[GodzilaAvenger]

Here's a possible solution: use the FRAMEINFO tool and enter ALL to get a *.json file of all frame infos of the RPU binary. Then use a json to xml conversion tool (there are even some online tools available).

[pandv2]

I am confused about removing and duplicating rpu frames at the same time.

If I want to remove the frame 10 and duplicate the frame 20. I need to do:

"remove": [
"10",
],
"duplicate": [
{
"source": 20,
"offset": 21,
"length": 1
}
]
}

Or I need to acount for the deleted frame:

"remove": [
"10",
],
"duplicate": [
{
"source": 19,
"offset": 20,
"length": 1
}
]
}

I am using DDVT injector with a custom.json.

I am suposing a delete doesn't changes the count for the next delete, and a duplicate doesn't change the count for the next duplicate. Is this true?

Thanks.

dovi_tool editor instructions

[fransalas]

thanks for answering before, could you tell me if there is any possibility of knowing the scenes of an MKV in HDR10, is that I am doing a test reconstructing a movie.

Thanks.

I have read that document before asking. Maybe, it is my understanding of english, but i am not sure what is the correct answer. I deducted:

1.- One remove doesn't affect the position of the next.
2.- One duplicate doesn't affect the position of the next.
3.- The remove's set affect the duplicates.

I am not sure if it's true. That's why I asked.

Note: It's correct. I tested as suggested by GodzilaAvenger.

[GodzilaAvenger]

I have the same understanding as you. To verify I recommend trying out dovi_tool (not the INJECTOR script) on the RPU and then using the FRAMEINFO tool on both the original and modified RPUs to see what has changed.

I'm not sure if I understand your question correctly. Do you want to know if a .mkv file is HDR10? If so, you can use MediaInfo to find out.

I haven't heard of an .mkv being capable of having both SDR and HDR scenes at the same time, if that's what you mean. It's either one or the other AFAIK.

Sounds correct to me.

Can you test if this file plays fine in regulard HDR on non-DV capable tv... like Samsung for example? I think it will not play because the codec ID is dvhe.
If you can test and it works even on a non-DV capable tv, it will be perfect.
Strangely Profile 5 DV with codec ID set to hev1 plays fine on both LG B8 and LG C2, even on a Samsung but with purple and green tint (which is understandable).
The problem is that the older LG's have some issue with Profile 8 with Codec ID set to hev1.

Does anyone have a proven DV profile 8.1 sample clip in MP4 to test on my Sony's media player? I can get a profile 5 sample to trigger DV mode, but the 8.1 ones I created using RPU injection while encoding in x265 or injecting afterwards and then converting the files to MP4 won't work. The Sony player can apparently understand DV only in MP4 files, and the links to samples at Dolby's developer site just error out.

Sorry, the only TV I have access to is my LG C8.
