EDIT: ok now this is strange... if I make a 1-minute sample, then no more error. but as soon as I'm working with the complete movie, the error comeback.
Can you share the full RPU? The error doesn't seem to be related to the HEVC file..

Thanks. I can reproduce with simple info:

Code: Select all

dovi_tool info --input RPU.bin -f 0
Parsing RPU file...
thread 'main' panicked at 'range end index 18446744073709551612 out of range for slice of length 1', src/dovi/rpu/mod.rs:23:54
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Will look into it.
FWIW my own RPU from a WEB-DL is larger, 35MB while yours is 24MB.
Oh nevermind that, I didn't convert to p8.

mm that's strange. AFAIK, there is only one DV release of this movie, the one from hotstar india.
does your version has the same MediaInfo as mine?

Anyway, I'll try to re-download it, maybe the file got corrupted in my HDD.

Sorry our RPUs are the same, mine wasn't converted yet.
Looks like it becomes invalid after converting only.

That's interesting what you talk about: can I add fake DoVi metadata (e.g. 1000 MDL, 1000 MaxCLL, 300 FALL) into a HDR10 stream, if so how?
(I want to create a small DoVi sample for FireStick 4k from a HDR10 sample to see whether it triggers tv-led or player-led with LG.)
Not currently but I'll make a tracking issue for it..
Feel free to add comments for specific things you might need: https://github.com/quietvoid/dovi_tool/issues/29
Thanks that'd be fine that way.

So I created a fake DoVi ts (with tsmuxer) after extracting the hevc stream from mkv and injecting a mode3 converted rpu from profile5 stream (tricky part was to find the exact framenumbers).
The result (260 MB, up for a week) is only played back as DoVi via Oppo, but HDR10 from Kodi-firestick and Plex (on LG) didn't recognised it: not sure why.

That's what I did:
extract rpu from profile 5 hevc dovi:

Code: Select all

dovi_tool extract-rpu video.hevc
edit and convert the extracted rpu to proper frame count and profile 8.1:

Code: Select all

{
  "mode": 3,
  "remove": [
      "0-32245"
  ]
}

Code: Select all

dovi_tool editor -i RPU.bin -j edit.json --rpu-out RPU_mode3_4.bin
add rpu into hdr10 hevc:

Code: Select all

dovi_tool inject-rpu -i video.hevc --rpu_in RPU_mode3_4.bin

I'm trying to understand the editor.

What would be the script if I have to add 24 frames in the beginning and remove the last 2 frames at the end ( or should I be removing 26 frames since I'm delaying the metadata 24frames??)

I tried this but it doesn't work. Please fix my stupidity lol

Code: Select all

{
    "remove": [
        "167703-167704"
    ],
	"duplicate": [
		{
			"source": 0,
			"offset": 24,
			"length": 10
		}
	]
}


Also, what would be the script if I want to remove 24 frames in the beginning and add 10 frames at the end?

this?

Code: Select all

{
    "remove": [
        "0-23"
    ],
    "duplicate": [
        {
            "source": last_frame - 1,
            "offset": last_frame - 1,
            "length": 11
        }
    ]
}

I think you need to swap the values of offset and length (length 24 and offset 10).
In fact, I suppose that the ideal would be to add the new frames after the frame that is taken as a sample (source), and not after frame 10 (length 24 and offset 0).

Thanks for this.
To me there seems to be a slight tint change (so maybe whitebalance difference).
Would be pretty complicated to tell if it's just because the HDR10 version was encoded differently.


I asked @manix to provide lldv capture sample with his Shogun, this will be a more accurate way of comparing the colors/tint.
Bitrate increase looks Amazing with the Rpu
U can see a difference a huge diff to me along with the hdr black bars.
Star Wars is like a whole new movie lol

Not sure about removing part (good question), but duplicating metadata of frame 26 in the beginning should look like this:

Code: Select all

"duplicate": [
		{
			"source": 25,
			"offset": 0,
			"length": 25
		}
	]

{
    "remove": [
        "0-23"
    ],
    "duplicate": [
        {

            "offset": frame_count - 1,
            "length": 11
        }
    ]

I tried to create an mp4 with mp4muxer (2020.03.06.) from the above files, but now everything plays it back as hdr10, even the Oppo:

Code: Select all

mp4muxer.exe --dv-profile 8 --input-file injected_output.hevc --input-file audio.ac3 --dv-bl-compatible-id 1 --output-file 1try.mp4
@quietvoid, do you know why?

Hope that @quietvoid will make an easy tool to be used by ignorant people like me as @Yusesope did for his tools.

I just pushed a new version to fix the "Soul 2020" DoVi RPU parsing once converted to profile 8.
You can find it here: https://github.com/quietvoid/dovi_tool/ ... /tag/0.3.5

Played Soul a bit with a sample and there were some noticeable brightness adjustments at scene changes.
Maybe because of the different black bars, I'd have to test more. This was simply mode 3 and removing the first 40 frames.

No, I'm not sure since I haven't used MP4 in a while. I can't remember if profile 8 ever worked.
I'll try your files and see.

If you mean including batch scripts and things like FFmpeg, then no it's not going to happen.
The tool is already a cross platform executable, so there's no other dependency required.

Your .ts file and when I remux it as MKV both play in DoVi on my Firestick with Kodi.
