MOD-File Transcoding/Streaming with XMP - [possible BUG]

[NDscham]

I tried the -q and it didn't make a difference to the output.

Enter this into subsonic's transcoding step 1. You can consolidate parameters- Should work similarly on linux.
Also check xmp --help to see if your version supports -q. Maybe the stuttering stops, if the logfile doesn't get spammed during playback.

Code: Select all

xmp -d wav %s -cq

I'll give that a try when I'm at the machine next time..

Quick question - are you going 4040 into subsonic, or 443 (or whatever you've remapped your ports to, if that's the case). Just wondering it that might be an issue, I had seen some mention of SSL streaming being an issue in some circumstances..

[NDscham]

Right, I'm accessing SS via https, but IMHO, that shouldn't make any difference as soon as the connection is established.
Regarding the current attacks on TLS & SSL, I might as well switch to unencrypted mode, though
Alright, I'll give it another try. Thanks for the hint, anyway.

Hi all

I don't know if anyone still are interested,but I've myself wanted to be able to play my "tracker" files.
I 've tried with XMP 3.3.0 win32 build which doesn't work right, a lot of static as other has mentioned.
After som testing I discovered that the issue is the way the PCM/WAV data is written to STDOUT.

So I decided to download the source code for the lastet version 3.5.0 and to first just try to build a new Win32 version.
Maybe the bugs was fixed in the later versions. But sadly the problem was still there.
I decided to patch the source code and now XMP works with out problems on my Windows 7 SP1 (x64), Windows Server 2008 R2 (x64) and Windows XP.

The arguments for the transcoding are

Step 2

Originally I also wanted to use the artist wildcard in Step 2, but that would fail, since Subsonic didn't know how to extract the artist name, and thus supply results in a "NullPointerException" in subsonic, so only XMP is getting launched.

Subsonic have a bug in regards to missing title, artist and album info...
If artist or album info is missing then SubSonic will result in NullPointerException if one is using the artist or album wilcards in the transcoding steps.
I do have a fix this, but I need to ensure that it doesn't screw anything else up.

I will try to make a patch (not a complete WAR file) for Subsonic 4.7 and I will also post a link to my patched Win32 of XMP 3.5.0 later today.

Cheers

Can you please post your patches? Just found this topic and very much want to get tracker files working!

Hi WACOMalt

Sorry about not uploading the patched version. But here is the patched version: http://www.slater.dk/subsonic/xmp.zip
Just extract it to the transcode folder and use the settings in my previous post.

In order to correctly to show the artist, title we would need to patch subsonic also.
At the moment I'm running Madsonic 4.8, and just using the transcoding settings shown in my post.

Hi,

Thank you for the patched version(3.9.1) !!!

Will you continue to build xmp(Win32) with the next version(4.x.x) ?

Cheers

[Otherland]

Hi bauxite69

Yeah I might do that, when I have some free time. The changes between 3.9.1 and 4.x are to big for just recompiling, the previous build setup doesn't work for me or might be bugs in the code in regards to Win32.
I'll will give a try, but exactly when I can not say, hopefully soon (I also like to use the 4.x versions)

Hi,

For those intersted, i managed to build the WIN32 version with the last XMP and LIBXMP sources.

Have fun !
