Seems to imply that 7,1 ALAC is 7.1 ch front where as the others are 7.1 ch rear.
"C Lscr Rscr L R Ls Rs LFE" vs "L R C LFE Ls Rs Lb Rb"
The thing I don't know if this is just a mappign issue and I can just remap "Lscr Rscr" to "Lb Rb"

I've never had that green tint issue so not sure if that's applicable. As for your other question, I'll shoot you a PM.davilla wrote: ↑21 Jul 2019, 12:09 Humm, https://www.reddit.com/r/appletv/commen ... streaming/
Does not work for meSmells like a tvOS issue, with AVFoundation codec, we do nothing regarding decode/rendering. The AV Foundation is handling everything. Dare I ask if Infuse can play it correctly? you will not get Dolby Vision but it should play.

Re: Dolby Vision
I don't know either.
I've done some tests withe the Amaze (Lossless-ATMOS) demo (DL HERE).
I've converted the Dolby Atmos track in PCM and then in ALAC.
Original PCM ######## (FL FR FC LFE BL BR SL SR ) (DL HERE)
Intermediate PCM ##### (FL FR FC LFE BL BR FLC FRC) (DL HERE)
ALAC ############# (FL FR FC LFE BL BR FLC FRC ) (DL HERE)
I can show you how the LAV audio Decoder handle the output channels for the three files
I've performed also a channel mapping (from 0 to 7) for the Original PCM and for the ALAC file and I've extracted the 6th channel from both(SL for PCM, FLC for ALAC).
After a conversion in PCM (PCM -> PCM for the first one, ALAC -> PCM for the second one), I've hashed the two output file using the md5 algorithm and the result is the same:
so, SL == FLC
Code: Select all
ffmpeg.exe -i alac.alac -map_channel 0.0.6 -c:a pcm_s24le -ar 48000 -rf64 auto FLC.wav
ffmpeg.exe -i original_pcm.wav -map_channel 0.0.6 -c:a pcm_s24le -ar 48000 -rf64 auto SL.wavI don't know if this can help you or it's totally garbage.
Today, I'm inspired so I have this for you (the video track and the audio track come from different sources):

Re: Dolby Vision
Ignoring the issue of audio, has anyone successfully gotten a DV UHD blu-ray converted to a single layer DV mp4 file using DVDfab to play back in Mrmc? Scanning through this thread it's not super clear to me. I have tried a few UHD discs using the latest version of DVDfab and cannot get any of them to work.

Re: Dolby Vision
haha so what if I'm like 9 years off
we can take a single layer dv mp4 from dvdfab and just swap the audio with the lossless one from the disc, minus atmos? I feel like I would have known about this if it worked, as it's always the old ac3, e-ac3, ac4, aac, flac, alac etc..-

Re: Dolby Vision
If this is about the xxxxxxxxx. HEVC AMS files, then those are actually valid Dolby Vision profile 5 bitstreams. The color space is ICtCp masquerading as YCbCr. If not decoded correctly, the colors will be messed up. Also, the color range is full for all Dolby Vision profiles.davilla wrote: ↑20 Jul 2019, 14:43 @timstephens24
UV sampling is screwed up. It's 10 bits yet Color range is Full, something I'd except for 8 bit.
Smells like a bad encode/transcode ?
Even video toolbox has messed up colors, but the generated thumbnail looks right. Which suggests it's really 8 bit and not HDR.
Is this a one off or do you have several like this ?
Did anyone actually confirm that profile 5 plays correctly? How about the videos in this post: https://forum.mrmc.tv/viewtopic.php?p=21661#p21661
I have mentioned before: DVDFab doesn't produce valid Dolby Vision profile 5 bitstream. The color space is still YCbCr.

Re: Dolby Vision
I downloaded some of those DV files from the google drive which was linked to in the other post that wesk05 just linked to and they all play with incorrect colors. But they do play.
