    anhlinhp4, your media-info shows your sourcefile to be 13GB. I think it leaves more than enough space on a single-layer BD disc for 5.1 pcm.
    TBH I don't understand why you still haven't tried this, if audioquality seems so important to you. Eac3to can uncompress your DTS-HD source audio to pcm and then stretch it. Choosing the right outputformat (w64 or pcm-tsm) the result can be directly imported into tsMuxer.

  2. sneaker, I agree with you. And as I said in my summary above, I've used AC3 file already (demuxed from my dts-HD file) for muxing it with tsMuxer. It's ok to use AC3 file.
    Ennio, that's right to say bluray disc 25Gb has enough space for my file with PCM 5.1
    knowledge that PCM is lossless from dts-HD (uncompress) and it's ok to use PCM 5.1 for my case, too (audio quality unchanged).
    I can use PCM 5.1 to mux back with tsMuxer. That's no problem.
    But here I like to get back dts-HD , and for conclusion, there is no way to get back dts-HD, right?

    P/S: By the way, when using Eac3to, choose output "pcm-tsm" as you guided, I get error notice: "Don't found Pcm2Tsmu.exe".
    What dose it mean?

    Ah, I think you don't have "Pcm2Tsmu.exe". You can download it here: https://forum.doom9.org/attachment.php?attachmentid=12552&d=1323596176

    Unzip and put the file in eac3tofolder. You can also use w64 as output for tsMuxer.

  5. HEY there every one....
    I tried to follow the steps in that steps provided in the forum and finally successfully converted a mkv TrueHD+Atmos to M2TS ...that is playable on my sony bluray(SONY BDVN9200W)...
    But there is a problem.....The source file i had was a 24bit....but after going through all the steps as Ennio instructed ,i was able to mux it in tsmuxer and the output now has a 16bit TrueHD and when i played it on my bluray, its not showing the bitdepth ...as it used to show it earlier, whether its 24 or 16Bit along with the audio codec that's playing on the bluray, if i press the mediainfo button om my remote.....and the file(TrueHD+ac3) i got out of Useac3to was 7GB+...but when i went through Mediainfo 17.10 after succefully muxing and creating a M2TS video files in Tsmuxer....its showing that the the TrueHD+ac3 is just 600mb in Mediainfo 17.10 !!!!
    So is there any solution for it ....so that i would get the output as 24Bit in tsmuser or, have i gone wrong anywhere during the process..?
    And i also noticed that ...the sample video file which Ennio (Atmos_trailer) has uploaded had the same media-info as i got ...if im not wrong...
    Here is the mediainfo of wht i muxed....Image

    Your image link doesn't work.

    Anyways, is it possible that eac3to stated the 24-bit audio as zero-padded 16 bit audio during examination?
    Check your eac3to log. If so, than the output will be 16 bit, with a significant reduced size.

    Have been slowly working my way through this thread and just when I thought I had it, TSMuxer keeps coming up with error msg of 'Cant create temporary meta file'

    I have searched and searched, I cant figure out how to fix this problem, really hope it is something simple that I am completely overlooking

    Thanks for all the tips along the way.....

  9. Hey there Ennio
    No there's no such thing shown to me on the eac3to .
    I hav uploded some of the screens,in that the one with the name muxed is the final video i muxed with tsmuxer,and other file has the original information of the video file.

    Download the Popcorn MKV convertor, open it up and then you'll have to wait a while for the audio toolsets to finish downloading.

    The convert is dead easy to use, just select an MKV file containing Dolby Atmos / TrueHD and under the settings tab in the top right select the TrueHD tab and tick the box to convert to Dolby Digital, hit run and wait for the output. A 10Gb MKV took about 20 minutes to convert the audio on my ancient PC.

    Once converted the new MKV file plays perfectly on my LG OLED TV via DNLA, I use Serviio but i'd be fairly certain it'll work with most streamers.

    Previously my TV refused to play Atmos/TrueHD audio within MKV files, it just displayed the error message "this video does not support audio".

    Did you try latest eac3to version 3.34? Maybe that'll help? I wouldn't know what else to help you out...

    @ennio

    just registered on the site to thank you, after found your solution at #4, spent the past 2 hours starting from scratch, had zero prior experience with remux/demux, just successfully created my first mkv atmos to m2ts atmos conversion, my receiver displays the audio signal correctly as such. I'm equally as thrilled as I'm tired, but a big thank you is a must!

    @ ennio

    for the past day I've been practicing the remuxing method you preached, after encountering a particular problem, I tried my best to scourge the net for relevant info and solutions to no veil, so I hope you could shed some lights or point me to the right direction.

    your method no.4 works, I'm able to convert mkv (avc format) with atmos soundtrack to m2ts with atmos.

    problem: what I cannot do with your method, is to convert mkv (hevc format containing hdr metadata) with atmos to m2ts with atmos "successfully".

    the really peculiar thing with the problem is, it's not even supposed to work, at all, to my limited understanding of the different formats that m2ts and hevc containing hdr metadata shouldn't even exist in the same realm of reality, but for whatever reason, my remuxed resulted m2ts file would display correctly on my LG oled tv as "HDR" video source through my blu ray player (along with embedded atmos sound track recognized and displayed by my receiver), it blows my mind! but the caveat is "successfully", as the resulted m2ts HDR file always have audio issues: either the audio and video are not in sync (video looks noticeably and unnaturally faster), or audio starts skipping at some point into the video (in this case, audio and video are in sync) and eventually completely breaks down the video and becomes completely silent.

    so far all I have to work with is the method you suggested in no.4.

    I have a slight feeling that I've encountered the muxing barrier with current video and audio formats, but any insights or suggestions would be much appreciated.

    teaching (learning) an old dog (me) new tricks is really fun. Thanks!

    I think I can't help you any further, other than that MediaInfo would probably state the bitdepth of the embedded AC-3 track, which your sourcefile (atmos only) of course does not have.
    I do try to carefully say that things are all right because of the MediaInfo data of the original .m2ts file, which comes from the original Atmos demo disc.

    Latest MediaInfo says on the original m2ts file also "Bit depth: 16 bits". So I wouldn't worry...??


    @ kaputpumpkin

    Note that I have zero experience with authoring/muxing HEVC to UHD-bluray or even m2ts for that matter. Maybe other people can tell you more. Or, hence the initial title of this thread, better open up a new one for this or search the forums on remuxing / authoring for UHD blu-ray. I couldn't even tell you what container is used for UHD bluray or that m2ts container is compatible with HEVC (with or without HDR or Dolby Vision), with (or even, without) Atmos.

    Maybe it's your player's capabilities? Did you try playing the mkv from a (fast enough) USB drive directly connected to your tv (and via ARC link Atmos to your AVR, if possible)?
    I'm sorry I can't help you further with this issue...

    Cheers

    @ ennio

    it's a looooooooooooong story. it wasn't until after I upgraded my receiver and speakers to atmos, I found out my gorgeous tv can't passthrough atmos over ARC. to circumvent the problem, I added a uhd blu ray player and moved away from streaming digitally from my tv, except for the digital movies I already purchased, I just can't justify paying for them again in physical blu rays (I know, I know...). So I downloaded these movies in mkv, just so I can finally experience what they are like with atmos. Turns out my blu ray player won't play mkvs containing atmos (go ahead, you can laugh, it's really more hilarious at this point than frustrating) except in m2ts container.

    The dog in me refuses to accept the fact that I can't take full advantage of the things I've spent so much money on, that was the initiative took me to this post. it's been a fun experience teaching myself new things, since I've never dealt with ripping/burning/muxing before, and I'm not a program by trade, but your suggestions no.4 was almost the perform beginning lesson for someone like me to dive into.

    I've since then moved on to learning encoding with ffmpeg (the amount of command lines seem really scary to me at first sight, but once again, the dog in me refuses to give in), and I've come very close to converting 10bit hevc/x265 formats, until the point I learned ffmpeg doesn't support atmos audio format, and that's the brick wall facing me. to my limited knowledge, it seems all the separate tools/programs are there: ffmpeg can encode 10bit x265 video, but not atmos audio; tsmuxer and eac3to can encode atmos audio, but not x265 video. I'm hopeful some talented programmers will figure it out and put the pieces together.

    for now, I'm content with the fact that I've learned so many new things, either skills wise or hardware wise on the limitation of my home theater system. I've done everything I can, and I'm okay with it (except not to get too excited about buying new video/audio equipment in the future without understanding anything and everything that are involved, sigh...).

    that's the end of my distraction from the OP.

  19. Neither eac3to nor ffmpeg can decode or encode Atmos.
    Both can:
    - decode the AC3 or TrueHD part of the track (ignoring the Atmos extension)
    - (de)mux AC3 and TrueHD including Atmos extension

    There is no free software to encode or decode Atmos. Even bitstreaming to an AVR is problematic with free software.

    Yep, no way you can create your own Atmos track, with freeware that is.

    I understand you are into HEVC encoding now. Having bought a UHD-BD player, I guess you're into 4K also. If you want to remux UHD to BD maybe you want to take a look here: https://forum.doom9.org/showthread.php?t=175120

    Besides my blu-ray players I also have a couple of stand-alone mediaplayers right next to them. If I go for a UHD-BD player in time, I'd also want a UHD mediaplayer next to it. It's just different types of approaching playback, and mkv-capability is a must nowadays IMO. Also, it's nice to have both for camparison reasons.
    What's holding me now is that, besides I'll have to buy 4K AV/equipment with required specs (think of HDCP, HDMI versions and all), I also understand I have to build a complete new pc-rig for UHD-BD playback and -ripping. I have a lot of reading to do about that. Also about re-encoding UHD-BD's (with ot without HDR) and last but not least, the editing and remuxing of 4K subtitles. I do a lot of them.

    I would not give up on my current mediaplayers (3D/FullHD) now, until I'm certain what to do with UHD/4K. I love playback over LAN via NFS protocol. Never had a hickup.
