HD audio bitstreaming from MKV container

[mc866]

I need some help folks. I got an ATI HD5450 for xmas and am now trying to get bitstreaming of HD audio working on MKV's. I can now bitstream direct from BR or iso using TMT5 but would like to also get it to work with MKV.

I've been using makemkv and another EAC3toGUI to convert my BR to MKV with the HD audio left in tact. When I try and play them back with TMT5 I think they get down sampled to DTS. Information from TMT5 says audio: DTS and my receiver confirms this.

Equipment I'm using:
Onkyo 607
HD 5450 with latest Catalyst drivers
TMT5

Codecs installed:
I can now playback 1080p MKV's in MC7 with DD or DTS audio using Haali's media spliter and AC3 filter. This also works to provide me with AC3 audio for my standard def avi files.

Any ideas here? What is everyone else using to playback DTS-HD and DD True-HD in MKV format? TMT5 should do it correct? The last thing I want to do is get into codec hell. I know Shark007 is a good pack but I've been attempting to avoid using all in one packs these days.

TIA!

Why are you converting the audio at all? If you want the HD audio just split it from your BD stream and re-mux it into the MKV.

That works but how? Steps or program?

Also I'm looking to reduce the file size a bit if possible, I guess that's why I was looking to convert in the first place. If the size isn't reduced much I'm better off just keeping iso's.

As Cogman said, just save out the audio as it is and at it to the MKV.
I am not a fan of MKV because while it is versatile , it is so versatile that people tend to screw up the encoding so it only works on their specific setup. Instead consider converting it to ISO. ISO is a much better format that doesn't require specific settings to use. You can use programs to shrink the video or drop features and still keep the iso format.

You can use imgburn to compile the final bluray iso.
-Load ImgBurn
-Select create image from files/folder
-Add Blu-ray folder
-In options, make SURE UDF 2.5 is selected. VERY IMPORTANT!
-Create ISO

Uninstall Haali's and register the latest mastroskasplitter.ax from the MPC-HC standalone codecs. Install the latest FFDShow Tryouts. Configure the output tab in the FFDshow audio decoder like this:


TMT5 will not bitstream from MKV, your options are most directshow based players (MPC-HC, Zoomplayer, WMP/WMC) from there pick a player and configure it to use FFDshow as the default audio decoder.

Using AC3, the file size isn't going to be reduce much if at all. You want to convert the thing to something like AAC if you want to see smaller filesizes (neroaac works well for this.)

Does bluray still use VOBs? If so, something like DGindex will be able to split the audio from the video.

Good info. I was under the impression that TMT5 would do it. I'm comfortable using MPC-HC for play back. If I have it installed already will I still need to register the latest mastroskasplitter.ax from the MPC-HC standalone codecs?

If I run audio through FFDshow tryouts(which I already have installed also) is that going to mess up the audio output of my other files as well when playing them back through MC7?

You can also use the clownBD software to do the conversions.

I prefer the hands on approach, but clown is easier to learn.

I did one conversion using clownBD from iso to iso but removing some of the unneeded content, funny thing was that the end result iso was larger than the original. I'm assuming I did something incorrectly.

If you are cuurently using 7mc for playback stick with that and find a program called win7dsfiltertweaker. All you need installed is ffdshow-tryouts and mastroskasplitter.ax (extract that to a folder ie c:\filters and open a command prompt as admin then run: regsvr32 c:\filter\mastroskasplitter.ax for 32bit or navigate to c:\windows\syswow64 and do the same command if an x64 version of windows). After that run win7dsfiltertweaker and set ffdshow as the default codec for all formats and disable the microsoft dtv-dvd codecs (both audio and video). After this configure the audio section of FFDshow and you should be able to play any mkv withing 7mc with full bitstreaming. This will not affect BD playback within TMT5.

Between the suggestions here and the guide below I was able to get bitstreaming to work through MC-HC

Trouble is I can't seem to get the settings to work for MC7 just yet which sucks because I like using media browser but I guess it's not the end if the world. If I somehow find a bunch of time soon I may do a clean install and try again. I have a feeling all of the changes I made originally with codecs and such are what's holding me back in MC7.

Thanks for the help.
