[Solved] DTS-support for UMS in Linux

[Fenzor]

I'm having an issue with DTS support with Linux. (Using 'Ubuntu Server 13.10')
This problem does not appear in Windows.
I have tested this issue with the latest version of UMS. (3.4.0)

Can someone either confirm this, or come with an solution?

An earlier post i made, conserning the same issue: (More in-depth)

I know there is low activity on this forum and that perhaps most people use Windows anyway...

But does anyone even use DTS on their UMS setup in an linux-environment?
If so, make a short reply down under...

Unless no-one uses DTS and/or no-one will confirm whether it works in linux or not.
I would say that DTS is unsupported until further notice.
But I can't say as one person whether this is true or not. I need confirmation.

I would try and help but right now i don't have access to my setup at home (DTS capable receiver etc..), and trust me i would get a linux box up just to help out. I can't believe no one else in the UMS community can answer this............

THANKS for answering, and for trying to help!

I'm not sure what's the deal about no-one else answering is, but the Linux-side of UMS-community seems rather small.
That in combination with DTS-support maybe being for specially interested only might be an contributing factor.

I am an student in Computer Science, but I lack the time to debug by myself.
Especially when i'm not fluent in the project's source-code...

But from what i have seen there seems to be a problem with piping the encoded data (from MEncoder and such) to the buffer-files.
That's the only part of the transcoding process i've seen that uses specialized Windows/Linux-implementations. (In encoding of DTS-audio context)
The trail of code has lead me to "PipeIPCProcess.java" and associated classes, but there my efforts have ended.

Edit: Added debug.log file...

Just another reason for me to wipe my server out and load Hyper-V

I would also check out VMWare V-Sphere (which i think was ESX-i) as it has better support for OS'es than Hyper-V. I only use it as i was running those machines on Server 2008 R2, i'd swap back to VMWare in a heartbeat.

[DeFlanko]

at least with hyper V it comes with server 2008r2...

VMware you need a licence...

After some testing I've got it working.

Firstly, tsMuxeR, issued with UMS, is not supported by 64-bit Ubuntu out of the box.
You've got to install 32-bit libraries like:
- lib32z1
- lib32ncurses5
- lib32bz2-1.0

After that I had to install "libgtk2.0-0:i386" with all dependencies to get my "libfreetype.so.6 cannot open shared object file"-issue to go away.

Now DTS-support should be back.
