- greysquirrel - 2012-02-08 I have been trying to keep up with the tech behind this but the last comment has confused me! this is the mediafile report for the truehd file. General Unique ID : 206879127696790850231049251004353230550 (0x9BA3787F23BB7D2887E378F19BCA36D6) Complete name : \\ZOTAC\Films\Kung Fu Panda 2.mkv Format : Matroska Format version : Version 2 File size : 18.6 GiB Duration : 1h 30mn Overall bit rate mode : Variable Overall bit rate : 29.5 Mbps Movie name : Kung Fu Panda 2 Encoded date : UTC 2012-02-07 20:11:19 Writing application : mkvmerge v4.2.0 ('No Talking') built on Jul 28 2010 18:38:23 Writing library : libebml v1.0.0 + libmatroska v1.0.0 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : [email protected] Format settings, CABAC : Yes Format settings, ReFrames : 4 frames Muxing mode : Header stripping Codec ID : V_MPEG4/ISO/AVC Duration : 1h 30mn Bit rate mode : Variable Maximum bit rate : 34.2 Mbps Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate : 23.976 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Language : English Default : Yes Forced : No Audio ID : 2 Format : TrueHD Codec ID : A_TRUEHD Duration : 1h 30mn Bit rate mode : Variable Maximum bit rate : 5 538 Kbps Channel(s) : 8 channels Channel positions : Front: L C R, Side: L R, Back: L R, LFE Sampling rate : 48.0 KHz Bit depth : 24 bits Compression mode : Lossless Title : 7.1 Language : English Default : Yes Forced : Yes I thought I had fixed the DTSMA problem as the remuxed file correctly displayed on the receiver. However, the problem seems to be that if I select a file having just turned the XBMC machine on, it correctly reports as DTSMA. If I then select some more DTSMA files then they start reporting as DTS, however then playing a normal file and going back will cause it to correctly register again, as I mentioned earlier as if it is 'resetting' the communication with the receiver. It's weird! - voip-ninja - 2012-02-08 ArieS Wrote:Are you sure it's working after it was ripped with MakeMKV? I just confirmed that you are correct, it is broken if ripped with MakeMKV. Some of my older titles were ripped with Clown-BD and those appear to be working fine, but the ones (Kung Fu Panda 2 for example) that I have ripped more recently using Make-MKV are broken, I get stuttering and tons of frame drops when playing them. - bluray - 2012-02-08 greysquirrel Wrote:My first thought was to convert to m2ts, tried with tsmuxergui and it won't open truehd audio. I only have 2 thd files at the mo, both don't work but main problem is Kung Fu panda 2. I will try reripping straight to m2ts and am in process of running dtsma files through Mkvmerge to see if that strips out anything. It must either be a problem with using Mkv as a container (surely can't be as others have it working) or more likely the version of makemkv I used caused tiny header glitches or something.Can you verify your BD file with MediaInfo to see what audio codecs are in it? You can download it from here- MediaInfo. - steelman1991 - 2012-02-08 T800 Wrote:Are the MakeMKV TrueHD files not working because they don't have the interleaved legacy ac3?Curious, what difference would the existence of a bog standard DD track have on playback? - a1sy - 2012-02-08 bluray Wrote:If I understand this correctly, you are connecting your system this way- HTPC-->Xonar via DVI cable and Xonar-->AVR-->HDTV via two HDMI cables. Did you selected Xonar HDMI output and configure speaker to 2-channel stereo in W7 control panel? You need to select the same Xonar HDMI output in XBMC audio output and Wasapi! I run Video card Nvidia 9600GT HDMI out to Xonar HDMI input. From Xonar output HDMI to AVR. From AVR HDMI video to Sony XBR4 52". Typically I mount BD ISO with Virtual Clone and Arcsoft TMT5 starts automatically, playing bitstream in pathrough mode. On XBMC, it says Wasapi: Speakers Xonar 1.3 Thanks - voip-ninja - 2012-02-08 In additional testing I observe that this patch also appears to allow for conversion of DTS-MA to PCM... is there an open source decoder for DTS-MA decoding? When I do PCM conversion of DTS-MA or Dolby True, everything works great, with no frame loss in testing so far. Only with bitstream do I get the frame loss occurrences. - steelman1991 - 2012-02-08 voip-ninja Wrote:In additional testing I observe that this patch also appears to allow for conversion of DTS-MA to PCM... is there an open source decoder for DTS-MA decoding?Nope only DTS core AFAIK, though DanielaE's first post would seem to contradict that. Like you I didn't think there was a suitable open source decoder available. - T800 - 2012-02-08 steelman1991 Wrote:Curious, what difference would the existence of a bog standard DD track have on playback? I remember back to my Popcorn Hour days when a TrueHD track needed the interleaved track in it to bitstream. All my HD DVD rips needed a legacy AC3 track interleaved into them that I created with eac3to. IIRC MakeMKV doesn't keep the interleaved track from Blu-ray rips. I could be wrong though. - steelman1991 - 2012-02-08 T800 Wrote:I remember back to my Popcorn Hour days when a TrueHD track needed the interleaved track in it to bitstream.Didn't know that - but having never owned a Popcorn Hour - had no reason to Don't know that it makes any difference as the other TrueHD files that I ripped using Another EAC3toGUI don't have the interleaved legacy track, yet they play flawlessly. All the files that have problems were ripped with MakeMKV build v1.6.14 (an August build I think). Clearly there have been newer builds since then , but I prefer Another EAC3toGUI or Clown BD for my ripping needs, so haven't used MakeMKV for some time - perhaps these issues are only shown in eariler builds. - ArieS - 2012-02-08 steelman1991 Wrote:All the files that have problems were ripped with MakeMKV build v1.6.14 (an August build I think).

Looks like I'll have to re-rip all my movies with TrueHD. At least the problem is not with DTS-HD as this is about 90% of my collection. Now THAT would have been a b!tch - greysquirrel - 2012-02-08 bluray Wrote:Can you verify your BD file with MediaInfo to see what audio codecs are in it? I posted the mediainfo for the truehd track just before your post. At least it isn't just me then! I only have 2 truehd files so no biggy to re rip, will try fab 8 and see if that makes a difference. - voip-ninja - 2012-02-08 Eh, I'm not going to re-rip over this, I will just disable bitstream for Dolby True and have it sent as PCM. PCM should be identical. - T800 - 2012-02-08 voip-ninja Wrote:Eh, I'm not going to re-rip over this, I will just disable bitstream for Dolby True and have it sent as PCM. Exactly! To me this is more of a bonus to play DTS-HD MA. TrueHD decoded will be just fine. - ArieS - 2012-02-08 voip-ninja Wrote:Eh, I'm not going to re-rip over this, I will just disable bitstream for Dolby True and have it sent as PCM.Doh! I had already forgotten about that... I'll give that a try. - voip-ninja - 2012-02-08 T800 Wrote:Exactly! To me this is more of a bonus to play DTS-HD MA. TrueHD decoded will be just fine. Yes, bitstream (or decode if it's really there) of DTS-MA is the really big deal here. |
