Great library, nice music, and well done help file! (without the classic silly yellow background)

@traumatic:

Your lib rocks ... as well as your tune

this looks like a cool library.

But, can it be used simultaneously with PureBasic's InitSound() and PlaySound() functions etc. or will there be problems doing this?

Thank you for your nice comments.
I knew I had to do some visuals in order to get some response!

I tested this and didn't encounter any problems so far.
Also I see no reason why the libraries should interfere.

There's just one thing to keep in mind:
[ov:Lib] supports different output devices while PB's soundlibrary does not.
Using another device than the primary may lead to unexpected results when
used simultaneously with PlaySound() but most likely you will just have 4
channel audio

i get error when i try to compile:
"POLINK: error: Unresolved External Symbol "_ftlused""
and more like that, 4 in total.

whats wrong?

What version of PureBasic are you using?
The library should work with v3.93 (and above).

roachofdeath · Post by **roachofdeath** » Sun Jun 05, 2005 5:06 pm

i use 3.92 for a few reasons, mainly being libs that dont work in 3.93 that i need to use...

can i have a previous version? that is if you still have it...
my e-mail is roach6390@gmail.com

This version should work with 3.92:

(NOTE: this version contains a bug in ovOpenMem() and lacks the optional loop parameter)

Please understand I see no reason in supporting older versions of PureBasic.

roachofdeath, did the old library work for you?

(EDITED)

Any chance to of a flac streamer too?
That way both ogg and flac can be streamed.

Naturaly I'm hoping that the PB 4 team will add a official ogg streaming
and flac streaming though

PS! is ov:Lib updated to latestogg vorbis version?

Good point. Is there anything I should be aware of / something that doesn't work?
(Actually, ov:Lib is using a customized library in order to reduce size.)

Yeah actualy, if you try to play a file and it's not a ogg file, the lib crashes,
instead of returning false when trying to open the file.
You can easily reproduce this with the demo program/code too.

And yeah, I suspected you had a slightly modified variation,
mostly based around vorbisfile lib I assume?
Maybe make use of that Test function if your not allready doing that when trying to open a file.

Other than that I think it's great, hardly any cpu usage at all,
the only thing I'm missing I guess is the ability to play more than one ogg file at the same time.
Imagine a game where you got a music piece (ogg stream) and
then you wish to change from the first music to the second without stopping any music.
(by starting a 2nd stream, and when it has started, fade out the other one)
Sort of cross fading if you know what I mean.

You're right about testing for a valid file, it's not checked at all right now... :roll:
Guess I'll have to add this for a next version.

About multiple streams, well, this has been requested quite some times now.
I never wanted ov:Lib to be like this but maybe it's time to re-think the idea.

Thank you for your response!
