Hello. I'm not sure if this is the right place to ask my question but I'll give it a try. I got this 720p .mkv file containing a V_MPEG4/ISO/AVC video stream and an A_TRUEHD audio stream. As far as I know, there's no solution for playing it as it is on the PC, so I thought of converting the audio to something like AC3 for example. I tried using tsremux, but when I open the file I can only see the video stream available for remuxing. I then thought of extracting the audio and converting it as a separate file, so I loaded the .mkv into mkvmerge and I was able to get a .mka file containing the audio stream only. Unfortunately, eac3to won't accept the .mka as input. I'm running out of ideas and I'd really appreciate some help. Thanks.
Make sure your codec package is up to date, I use CCCP, which has FFDshow. Configure the audio settings to have LibavCodec decoding TrueHD streams. Play the MKV with Media Player Classic, which is also included in CCCP. You might also need to install Haali Media/Matroska Splitter. Eac3to does accept MKA as an input, you could also try tsMuxeR (not tsremux). tsMuxeR can demux and accepts MKV as an input. Might I ask, where did you find a MKV with TrueHD?
odin24, thanks for your answer. My CCCP is up to date and FFDshow is set to decode TrueHD using libavcodec (I guess it's a default setting). I'm playing the file with MPC and I get no sound, Haali shows only the video stream, also FFDshow loads the video part only. I've just tried tsmuxer as suggested and I get "unsupported format" when opening the .mkv ("Some tracks not recognized. These tracks were ignored."); it shows the video stream only. It looks just like there's no sound stream at all, but MediaInfo detects the TrueHD audio and also mkvinfo/ mkvmerge. In fact, mkvmerge was the only app capable of extracting the TrueHD stream in a .mka container. The only problem is that .mka is not a valid extension in eac3to (.thd is, for example) I downloaded the file from the docspedia.org tracker, it's a Cirque du Soleil 2004 show called "Midnight Sun".
Have you tried using the original MKV as an input using eac3to. I know eac3to accepts MKV as an input... and I'm fairly certain it accepts MKA as well.
If you have the latest CCCP, try VLC player. I had the same problem as you with my own blu ray rip that had a TrueHD stream. Couldn't get audio with MPC. Once I updated my CCCP, VLC recognized it.
