Haven't seen this codec before

I am still encountering an occasional issue with some of my UHD movie rips. I'm trying to play it on my Roku TV. This one in particular I didn't notice before. While the UHD case calls it Dolby TrueHD with Atmos, MediaInfo is reporting it a little differently.
  Code:
Audio #1
ID                                       : 2
ID in the original source medium         : 4352 (0x1100)
Format                                   : MLP FBA 16-ch
Format/Info                              : Meridian Lossless Packing FBA with 16-channel presentation
Commercial name                          : Dolby TrueHD with Dolby Atmos
Codec ID                                 : A_TRUEHD
Duration                                 : 2 h 7 min
Bit rate mode                            : Variable
Bit rate                                 : 4 991 kb/s
Maximum bit rate                         : 7 662 kb/s
Channel(s)                               : 8 channels
Channel layout                           : L R C LFE Ls Rs Lb Rb
Sampling rate                            : 48.0 kHz
Frame rate                               : 1 200.000 FPS (40 SPF)
Bit depth                                : 24 bits
Compression mode                         : Lossless
Stream size                              : 4.44 GiB (9%)
Title                                    : Surround 7.1
Language                                 : English
Default                                  : Yes
Forced                                   : No
Original source medium                   : Blu-ray
Number of dynamic objects                : 11
Bed channel count                        : 1 channel
Bed channel configuration                : LFE


Is Meridian Lossless Packing something we can capture with a profile? I don't see it listed as a Matches codec. Or is this just the way that TrueHD is identifed?

My Roku TV is playing it without transcoding, but several minutes into the video it stops and reports the file as unplayable. I've encountered this before with DTS Master Audio: playback starts but then stops with the same error. For DTS/MA, I just transcode to DD and it plays fine. But the console is reporting this as no transcoding. Since no Roku supports any lossless audio codec, I am very puzzled why this even plays at all, regardless of the error message.

I also discovered an error in the Roku 4K TV profile, where it is transcoding video when I meant to only transcode the audio. I will submit an update for the next version.

Re: Haven't seen this codec before

Looks like it's something that MediaInfo is interpreting differently (or just embellishing) then FFMPEG. Here's the FFMPEG info.

  Code:
 Stream #0:1(eng): Audio: truehd, 48000 Hz, 7.1, s32 (24 bit) (default)
    Metadata:
      title           : Surround 7.1

Re: Haven't seen this codec before

Sony has been removing DLNA functionality for years. I have an older BD player (BDP-S3500), and use the same profile you mentioned. While my previous Sony BD player would play both DTS Master Audio and Dolby TrueHD, the S3500 only plays TrueHD over DLNA. It sounds like they've removed that functionality from yours completely. Which means audio transcoding will always be necessary.

For your UBP-X700, there really isn't a good Serviio profile for it. Your player is 4K, and there is no 4K Sony profile. So any UHD material is being transcoded unnecessarily. I don't have such a player, so can't offer much help developing a new profile for it.

This can not be!
Serviio plays back 4K HDR10 files with TrueHD Atmos soundtracks beautifully. Absolutely no complaints.
Here the problem is on Serviio side.
Same files I can play back when I open the Plex DLNA server on X700. But on Serviio file lists these particular files do not appear at all.
So this is definitely not a problem on Sony side.
I really hope that Petr can look into this.


I'm looking at the BDP-Sx100 (2013) profile, and don't see any lines that catch TrueHD, but I do see a line that catches H.265 video and transcodes both the audio and video, as well as sets a maximum video bitrate. The video is transcoded into MPEG2, and the audio into standard Dolby Digital. I can see that a H.264 movie with TrueHD would audio pass-through, but every 4K video on UHD Blu Ray I've ever seen has H.265. If you're watching a 4K video with HDR and TrueHD/Atmos, and your AVR is reporting TrueHD/Atmos, then you must be using a different profile. As I said, my current Sony BD player (not 4K capable) will pass TrueHD/Atmos, but not DTS Master Audio/DTS:X. It either reports an error about unsupported audio, or there's just no audio at all.

Plex has it's own custom profiles, and most likely has support for a player as new as yours. As I mentioned, Serviio hasn't had any Sony profile updates (to my knowledge) for several years. The newest TV profile is dated 2014, and the newest player profile is the one you are using (2013). These may have been tweaked over the years, but there hasn't been any new profiles specifically for supporting the 4K players.

Re: Haven't seen this codec before

Cool. Just needed to confirm you weren't transcoding. Just as an aside, if you enable burned in subtitles it will transcode even if you have it turned off.

It's great the UBP-X700 still supports TrueHD. How about DTS MA/:X? Are you getting that to your AVR? If so, then that's the next BD player I need. :D

Yes, Serviio feeds all lossless audio and has no problems with HVEC or HDR. I've ripped 5 UHD Blu Rays, and they all stream perfectly to my Shield. My Roku players buffer, but that's because they don't have a Gigabit Ethernet connection and my WiFi doesn't seem to stream as well as a Fast Ethernet connection.

Hopefully Petr can determine if there's something he can do about the issue you have identified.

Actually, if the m2ts is straight off the disc (decrypted, naturally), then it will play it back as if from optical. You will lose the metadata, obviously, as the BD m2ts does not contain any, they are kept in other files (CLIPINF and PLAYLIST).

Yeah, my S3500 will display captions from M2TS files, but not from MKV, although the player recognizes there are captions available.
priitv8 wrote:The only thing it won't do, is the Dolby Vision of the bluray kind (the 2-video streams flavour, aka Profile 7). That second enhancement stream is only being processed when coming from optical. DoVi Profile 5 can also be streamed from Serviio or Plex.

I don't have a DV capable display, so can't comment on that.
Yes, they do. Actually with even less problems. DTS:X plays also from MKV file. Atmos only from m2ts. That fault is with MKV, not the Sony player :)

I don't think it's because of the MKV container. With my Shield I can get DTS:X and TrueHD/Atmos from MKV and M2TS files without a problem. But that's great that it supports both lossless codecs. I can now consider one of those when I need to replace the BD player. Thanks!

DTS MA files will play the DTS core track sometimes, so that would explain why they would start to play. But overall Roku doesn't even care for that, so after playing a short while that happens.
