Cool VL Viewer forum

I've noticed that some audio streams are buffering in 1.26.9.16. They play for 10-15 seconds, pause and resume. This is not happening with all streams and does not happen in the LL release client nor Firestorm.

Can I get a pointer as to which logs, etc (if any) I can collect and send to you for this issue?

Thanks/

This is probably due to your network connection getting filled up with texture downloads (the Cool VL Viewer is very fast, faster than most other viewers when downloading textures, so it consumes more bandwidth while rezzing): you could increase the buffer size for streaming music ("FMODExStreamBufferSize" debug setting which defaults to 7000ms = 7s) and/or decrease the "Max HTTP requests" setting (in Preferences -> "Network & Web").

For the required logs, see the rules for this forum (but it's not really a bug, here...).

I can replicate the issue.

Anytime I encounter a land stream at 64kbps or lower I would see the pausing issue. I saw it pretty consistently at streams I create since I always make mine 64kbps to save bandwidth. Once I bumped the same stream to 128kbps, no pauses at all.

I'd say this is a bug since you would think that buffer overrun issues would occur with faster, fuller streams, not slower ones.

(Just my opinion).

It cannot be a viewer bug. FMOD Ex may be the culprit, but I'm still to see it happening here. Also, you didn't provide any log, so it's impossible to tell what's happening for sure.

Here are the relevant log lines before I switched the stream (at the server) from 64kbps to 128kbps:

(repeats as long as the stream is open).

Once I switch the stream (same server, just changing the Shoutcast config to stream 128kbps instead of 64kbps), these lines disappear and the stream is fine.

The viewer behaves perfectly normally, reacting to the starvation as it should: 64Kbps is simply insufficient a steaming speed for the music stream encoding.

64 kbps is perfectly sufficient and has been until the last FMod EX update (in 1.26.x.17 or so)
