Dolby Vision now possible through MP4 Mux.

the video look corrupted. The artifacts are present on MPC as well.
Which title is this exactly? I've never seen anything like this and I watched tons of P8 NF content.

MPC attempts to read and map DV metadata though, correct? For DV5 > SDR mapping IIRC? I think the issue is somewhere DV info is being left behind when it shouldn't be (either because the original files themselves are structured wrong or whatever) - and because these players parse DV info - they attempt to display it - where as players that do nothing with DV so the info is gibberish to them - they don't attempt to display it so don't

I'll DM you all the stuff I've noticed it in

Edit: I'm thinking of MPV for DV5 > SDR mapping, not MPC, my bad

No rpu used. I use madvr and it doesn't render the rpu at all.

Yeah I confused MPC and MPV

Edit: As mentioned in the DM - I think it is the files (metadata or something) are structured wrong or something - and that's why Dovi_tool doesn't remove it or whatever - because it's not looking for/removing data where it knows it shouldn't be? Because as mentioned in DM - one title was able to demuxed and playback fine with no artifacts - but only one file

I'm gonna forward that DM to quietvoid too

I just tested that scene and no problem on my end. (MPC or windows DV player)

Your file plays fine for me (edit with and without DV extensions installed)- so it's gotta be a version of authoring tools I'm using? ts_muxer and GPAC is it on my end?

I used mkvextract to demux and mp4box (my script 7-1-1) to mux to mp4.

OK I'll try this later on (gotta make dinner) and report back

Sorry quietvoid

[Hellboy.]

it shows this way both on Windows with the DV extension installed, and on my DV capable Android TV - so it's not just a Windows thing

What DV extension and player you use to see DV on Windows?

Install that and then either the Microsoft Movies & TV app or the new Windows Media Player (from the store only not the built in WMP)

It works with mp4 only not mkv and DV8 and DV5 only not DV7

Reset said he doesn't like the accuracy of it IIRC (not color/PQ accurate or something)

Hello @RESET_9999!

I have a question regarding the best way to playback DV FEL files. My setup is almost the same as yours (LG C2 and a Denon AVR) but i have a shield Pro.

I was wondering if upgrading to the x800m2 would be a good idea as it has FEL support but i was looking at previous posts and saw that the L1/L2 bugs affect this player.

Is there any difference between the two players for DV playback (besides the red push in the shield which I also see)? What is your current setup?

[staknhalo]

I used mkvextract to demux and mp4box (my script 7-1-1) to mux to mp4.

Hey - I tried just using mkvextract first just to A/B test what the problem might be - and had the same issue - but that led me to notice your test file that played fine for me is codec ID hev1 - whereas mine come out hvc1 - I thought mp4box only spits out hvc1 unless DV5? And that the Dovi mp4muxer is what spits out hev1?

quietvoid said it looked like decoder errors - and isn't the codec ID SW (hev1) vs HW (hvc1) based decode? And that's why on Apple hev1 stutters?

[RESET_9999]

I thought mp4box only spits out hvc1 unless DV5? And that the Dovi mp4muxer is what spits out hev1?

7-1-1 in my script doesn't not use the mp4muxer unless your input has 7.1 lossless audio. It's mp4box doing the muxing and the people that tested on the appletv did not complain about stuttering.
so the test file I sent you is from mp4box only.

overall, the x800m2 (or oppo and x700) easily wins over the shield in terms of quality.
Not to mention that some bluray lately has been using FEL to expand the brightness of the BL and these blurays can only be played properly on FEL devices.(unless you bake FEL into the BL)

so the test file I sent you is from mp4box only.

What command did you use through mp4box (through your scripts) to get hev1 codec then? And the test file stutters on my iPhone just like when me and the Chinese guy here were figuring out the whole stuttering thing with the hev1/hvc1 codec ID. I can try and screen record that if you want.

You might want to check if a line in one of your scripts is off and it's sending stuff to mp4muxer instead of mp4box? Look at the codec ID of the file you gave me and try pumping another one out through command line only and mp4box only yourself - without going through your scripts at all to eliminate it possibly accidentally using mp4muxer?

Here's your file codec ID



Here's directly piped out though mp4box with command line:



Your file also doesn't have the mp4box bug of listing HDR10 over and over when a DV file

no it's not.
As I said, only if your input has lossless 7.1, then mp4muxer will be used because mp4box choke on 7.1 EC3 audio muxing.
