The X700 is a wonderful machine and if you don't care for Atmos + DV from pirated movies, it will play anything else fine, including the actual UHD blurays.

who said anything about pirated movies?? A huge amount of people care about disc preservation where you watch it once or twice (or sometimes never even open it if it's a rare steelbook), and then just make a digital backup so you can view it to your hearts content without touching the physical copy. If you paid for the disc, you should be entitled to watch the backup in its full glory and not have choose between better picture or sound quality.

Let's be real here. The only reason there is so much interest in this is to pirate videos. I have YET to have a failed VHS, DVD, Bluray or UHD Bluray since I started using physical media in 1994. Don't even try to give me the argument of media preservation . And realistically, how many times are you going to watch a movie? By the time the media wears out (which it won't), 8K remasters will be here on newer media.

I strongly appreciate the work you and others are doing in regards to DV on local playback. But to say the driving factor is media preservation is simply not true. Also if you want media preservation... just rip and reburn the bluray. Or better yet if you want convenience of no disk, do what 99% of the population does and stream via Netflix, etc.

It's been a while since I've played with mp4muxer, mp4box and ffmpeg.
I used to remux both layers with ac3 audio into a mp4 container which works fine in both the Plex and Xplay app on my LG C8.

However it seems some people remux the hd audio track into lpcm 7.1 audio.
I assume you only lose the Atmos positional metadata.
But it's still better than ac3 since it's lossless.

But does the lpcm 7.1 audio play in the LG plex or Xplay app?

I know I can probably not hear the difference using the built-in speakers and regular arc only allows up to eac3 (dd+)

But if it's able to play then it's better for preservation I guess. Since playing it on devices connected to my amp directly will benefit

I think the Sony dv support is the worst.

http://4k.com/news/sony-explains-about-dolby-vision-problem-in-its-4k-hdr-tvs-partly-blames-others-23168/ wrote:Sony implemented a modification to Dolby Vision support by which most of the processing for playback of content with this kind of high dynamic range formatting is offloaded to the device from which it came from instead of being done inside the TV itself. Thus the need for complementary updates from streaming device makers. Why Sony chose this approach is still unknown but it could be because they wanted to make their Dolby Vision update as lean and easy to implement as possible.

Philips 804 is an android tv with a built-in Video player that can handle dual layer dv.
This is surprising that nobody tried to backup this android application, to try it on another android device

Hello! I have two questions about Dolby Vision muxing process.

Some users on this thread reported that dual layer mp4 works with Sony UBP-X700 players, and with LPCM 7.1 sound. How exactly have you prepared files for the playback? Have you used DVDfab or other software? Have you converted TrueHD stream to LPCM, and if so, how that was done?

I also have a question about mp4muxer tool from the first post in this thread. Does it allow converting dual layer DV to single layer? If so, how exactly it is done? I've tried it on Windows, Linux and Mac, and it never delivers the results. The tool always fully reads through the supplied files (~60 gigs in my case), it writes ~600 megabytes of output file (equals to the size of supplied .ac3 track), and then it just freezes. Has it worked for anyone?

Thanks.

It is not advisable to demux both base layer and dolby vision layer at the same time right? As in we need to demux those one by one instead? I did that with Hellboy 2019 and it got massive stutter during playback.
