Thanks @shawnc22 . Or you can try this W64 build bb51a5f from my fork. Single tracks created from Blu-rays should be profile 6.

Code: Select all

    // cf. "http://www.dolby.com/us/en/technologies/dolby-vision/dolby-vision-profiles-levels.pdf"
    int profile;
    if (m_sps->bit_depth_luma_minus8 == 2)
    {
        if (!isDVBL)  // dual HEVC track
            profile = 7;
        else if (m_hdr->isDVEL && (V3_flags & HDR10))
            profile = 6;
        else if (m_hdr->isDVEL)
            profile = 4;
        else if (m_sps->colour_primaries == 2 && m_sps->transfer_characteristics == 2 &&
                 m_sps->matrix_coeffs == 2)  // DV IPT color space

            profile = 3;
        else
            profile = 2;
    }

We support profile 4 MEL (minimum enhancement layer). Also single layer profiles 5,8.9.

A way to remove HDR10+ without removing Dolby Vision?

Cheers.

Curious if this will play on the shield, I think not because the devs said profile 4 MEL, 5,8 and 9 are only supported.

We support profile 4 MEL (minimum enhancement layer). Also single layer profiles 5,8.9.

Joker sample file that's been used extensively here before with no audio track:
- Plays on B9 internal player, triggers DV
- Plays on 2019 Shield, triggers DV

Full Joker movie remuxed with Atmos audio:
- Plays on B9 internal player (no stutter), triggers DV, and no audio support message (as expected)
- Plays on 2019 Shield, triggers DV and Atmos audio

Here is the resulting mediainfo from the full movie remux:

Interesting findings as my previous remux of the full joker movie that was prof 4 did stutter on my B9, so seemingly the stutter issue on the LG internal player is related to DV profiling. Also interesting that the Shield is able to play these since it's been mentioned in that past that profile 6 is not supported. As far as my eyes can tell, there is no discerning difference between the profile 6 vs 4 DV remuxes. Not sure what the best step is moving forward, since profile 6 has pretty much been deprecated? I had to go back to a 2016 version of the dolby profiles pdf to even find a mention of it.

Now if profile 6 works on both the Shield (also playing the Atmos track) and LG.. then -mode 1 with profile 6 in TS should be the golden combination.

shawnc22 wrote: Mon Mar 30, 2020 5:34 pm I don't know if it's as simple as saying that prof 4 is no good on the LG. The same Joker sample file that I had previously made in prof 4 played back perfectly with no stutter, it was just the full movie that was stuttering. Plus this official LG sample here: https://4kmedia.org/lg-dolby-comparison-uhd-4k-demo/ is a profile 4 TS with a BL+EL+RPU single track, and that plays back just fine, too

@shawnc22 thanks for the confirmation on profile 6 working. The patch is pending merge in the official tsMuxer.

Mediainfo must match the following:
- Profile 4: BL+EL+RPU, SDR or (Unspecified colorspace)
- Profile 5: BL+RPU, (Unspecified colorspace)
- Profile 6: BL+EL+RPU, HDR10/+ compatible
- Profile 7: track 1 HDR10/+ compatible, track 2 HDR10 compatible
- Profile 8: BL+RPU, HDR10/+ or HLG or SDR compatible

Edit: Dolby are cutting all compatibility with other HDR formats, so indeed they don't advertise compatibility with former profile 6. And profile 8 is already in "Annex I: Profiles not supported for new applications" in the latest DolbyVisionProfilesLevels_v1_3_2_2019_09_16.pdf

Can also confirm the 2019 shield and LG C8 plays the Profile 6 files just fine. I did not watch an entire movie but testing 2 movies worked just fine.

Edit: 1917 studders on the LG C8 but plays fine on the shield. (profile 6)

Now if we can just get Nvidia to fix the color issues on the shield playing back Dolby Vision we might get somewhere
