Simply i want to know if will be a Seek function for sound streams.
Thank's for all!

That's impossible, a stream is not loaded in memory.

Why does that make it impossible? Wouldn't that just make it take longer to go get the new chunk from the HD?

It could potentially be possible for sf::Music (if underlying libraries allow it), but definitively not at the SoundStream level.

I'll check that and let you know

Well, i'm talking about seeking a music file, like any music player, i didn't want to say to implement the seeking function on SoundStream class. And basically i need this for ogg files. So i think that it's possible.
Thank's for all!

What is sf::SoundBuffer::GetSamples() for?

I thought it was for seeking through the samples to get information.

Yes it is. But it doesn't allow you to change the current playing position.

Ohh! That kind of seeking.

I guess that's what SpartanJ wants

Hello,
any news about setting the current playing position?

For example I would like to invoke the "play" method with "from" and "to" parameters expressed in milliseconds.

Is this change in your thoughts? :wink:

Laurent · « **Reply #10 on:** July 29, 2010, 01:39:17 pm »

It is already implemented in SFML 2

Limo · « **Reply #11 on:** July 29, 2010, 02:18:56 pm »

Very well!

I see that I can use SetPlayingOffset to define the "start" position but I can't find how to define the "end" position. I would like to play just a piece of music, not from "start" to the end of the file.

Laurent · « **Reply #12 on:** July 29, 2010, 02:29:12 pm »

There's no direct way to do it, but you can watch the current playing position and stop the music as soon as it reaches the desired value.

Limo · « **Reply #13 on:** July 30, 2010, 07:58:42 pm »

Do you mean to use a thread and polling the current position?
This way the precision is limited to the polling time interval.
SFML should be "Simple"... :wink:

Kind of... ok, bad solution

I'll see if there's an easier solution.

Simple for what it allows to do, it can't contain easy functions for every single feature that people want
