Cool VL Viewer forum

Sometime in the last 2-3 versions (.13, .14 and .15) when a parcel changes the Audio URL, the resulting music loops in 1 second loops. For example, if the song is 'La De Da', all that plays is 'La La La'. The only way to clear the issue is to log off and back in.

I have been unable to replicate the issue on my own parcel. However, I listen to lots of live music. If I don't stop the music playback before they switch streams, the looping will happen almost every time.

I've attached the log from the last instance. Once the looping started, I clicked exit.

This would correspond to FMOD Ex v4.44.55 introduction... Tomorrow's releases will have v4.44.56, so we will see if it makes a difference for you...

No change with today's version (1.26.15.2 - v4.44.56)

Log attached.

I'm afraid I can't do anything about it, since it's a problem with FMOD Ex...

You could try and use the DLL from FMOD Ex v4.44.54, and see it it solves your issue.

This still happens with 1.26.15.3 when an audio stream ends and a new one starts:

2015-08-16T00:15:49Z INFO: LLStreamingAudio_FMODEX::update: Stream starvation detected, muting stream audio until it clears.

2015-08-16T00:16:11Z INFO: LLStreamingAudio_FMODEX::start: Starting Internet stream: http://....

The new stream starts and loops. Even if I then tp to some other parcel with audio stream, that music loops too. Only way to fix it is a relog.

It doesn't happen with other viewers that use the same FMOD Ex 4.44.56

I'd be curious to know which viewers you are speaking about... LL's current viewer is still using v4.44.31, Singularity and Firestorm didn't get a single release in months (and 4.44.55/6 are only a few weeks old)...

Since the initial reporter pointed out things were working fine in the releases done before I introduced v4.44.55 (and since I didn't change any related code in the viewer itself in the mean time), please, grab v4.44.54 (if you got 7zip, you can rename that file using a 7z extension so to extract the DLL directly from it), and get the fmodex.dll (in the api/ sub-folder) file from it. Then replace the corresponding DLL in the Cool VL Viewer installation folder, and let me know if you encounter the same issue with it...

I extracted the 4.44.54 fmodex.dll and put it into the Cool VL Viewer folder and the bug is fixed. Great! Thank you : )

The Firestorm Pre-releases use FMOD Ex 4.44.56. With the 64bit version 4.7.3 (47315) from Aug 12 2015 21:22:49 I didn't notice any audio stream loop bug.
I only installed it for checking. I prefer Cool VL Viewer.

Let's hope the next FMOD Ex version will get things straight again...

Perhaps the 64bits version of FMOD Ex is not affected, or perhaps Firestorm's code is not triggering that particular bug (it's probably a race condition, so it could appear at seemingly random times, depending on network activity and/or other threads)...

I am sorry, i should have tested better. The bug is still there, with the older dll 4.44.54. I like to go to live concerts and have to log out every hour when stream changes, to fix the loop.

I also tried the 32bit pre-release Firestorm 4.7.3 (47320) for SL and OpenSim now, with FMOD Ex 4.44.56 and loop does not happen.

I tried hard to reproduce the bug here, under both Linux and Windows, changing my parcel music stream from one to another, many times, in various ways, to no avail... I suppose it's one of these system-dependent race conditions that I will never be able to reproduce myself...

I made a small change that could plug one such potential race condition (but that's just guess work from me) and added more debug messages in order to try and spot what is the exact code path involved in that bug. I compiled a test build and will give you the link to it in PM, so that you can test it; if you still encounter the bug with it, please enable the "FMOD" debug tag after the viewer restart and login (from "Advanced" -> "Consoles" -> "Debug tags"), then wait for the bug to occur, log out, and post the log here (the *full* log, please !!!).
