 Description  « Hide
hello linux lindens,

here is a user side debug session which might help to
find the bug which hangs the linux client while playing
ogg/vorbis streams from the outside.

the console output ends with the line

      • glibc detected *** malloc(): memory corruption: 0x0eea03e8 ***
        when i press the music play button in the client.

first you get the console messages, then the used trace command
followed by an excerpt from the trace.

in a second session i started bin/do-not-directly-run-secondlife-bin
with constructed environment through valgrind. valgrind just got
a SIGSEGV in the start up and stopped. nevertheless i appended the
output of valgrind.

thanx,

tx Oh

I know Tofu for one is aware of this bug, and the bug lies within fmod. Streaming audio is handled completely within the fmod library. As not even Linden Lab gets to see the source to fmod, this bug can't be direcly fixed except by the fmod developers themselves.

The only way to fix this is to implement our own streaming. Which we will have to do anyway one way or the other if we are to move to OpenAL...

Also, this bug affects OSX as well. ogg streaming has never worked in OSX either.

It looks the fmod developers have fixed the bug. The problem is that secondlife uses an old version of fmod.

If by "new version" you mean fmod 4, the API is completely revised and the licensing is different. So it's not a trivial upgrade.

OpenAL support is nearing completion anyway. OpenAL is the way forward.

Looks like a fix is on the way, but just in case it helps, I saw this in 1.19.4, with the same error tx mentioned:

From the 1.21RC0 release notes:
http://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Release_Candidate/1.21
"Fixed: VWR-219: vorbis radio streams crash linux client"

It doesn't seem to be fixed totally. I tested first by setting a local ogg vorbis file as my parcel's music. Instantly crashed. Then tried Virgin Radio's ogg stream. Nothing. However after the first crash when setting to a local vorbis file, it does play for about 3 seconds, then the client crashes. I guess that's progress, but it's still premature to call it fixed.

how long can such a fix stay in a pending state?

The intended fix was shipped with viewer 1.21.
However you are reporting that this is not completely fixed, so I will reopen. We do not currently have any improved fix yet complete.

hi,

this issue isn't and wasn't ever fixed.i use the nightly build 1.21.6.98973 and rechecked it 1 minute ago. if you play an ogg vorbis audio stream on a parcel your viewer will crash.

i updated the environment.

Rendered obsolete by the incoming OpenAL stuff!
