Hi all,
Ive noticed that when I want to load a piece of music (background music) thats pretty large (1 - 10Mb), a long pause appears which worsens when the larger the file. I know that this is the case because of compiling the audio moving it into ram…etc.
What would solve this problem is streaming. So the file would stream from the HD instead of being in ram.
What do you think of this idea?
And arman, is this feasible with the current infrastructure?
DP
I’m certain that it’s possible, and it’s an excellent idea for jME. I’ve written a streaming Oggg loader before, perhaps I could contribute that to jME? The addition of streaming might require a few small design changes to the sound architechture, though.
I’ll look into it once fragment programs are finalized.
Streaming would be cool. In the meantime, you can always preload your music or load it in a background thread of lower priority (not too low though or it won’t ever load. :))
im currently preloading them. But the loading is a io operation which blocks the current thread. So Im going to have to load in another thread.
DP
Just my .02 here…
I agree that streaming audio would be a great addition… I can think of all kinds of situations that would benefit from this functionality…
- Live audio from a network game (players talking to each other? announcements from the game manager?)
- Handling gaming machines with less-than-ideal amounts of memory and/or generally reducing the memory footprint of a game
- Decreasing the load time for the game and/or levels in the game
- Playing CD-audio from the game CD (or let the player pick his own CD music?)
There are probably other benefits as well… these are just what I thought of off the top of my head.
–K
It can also hurt the speed if the sound is loading from a slow drive. Another problem would be if the program needs exacted timed sound. For these reason I think that streaming should be optional.
streaming will be optional ofcourse. However, solving some of your problems would be to set a buffering stage whereby it writes "some" of the sound data (user configurable) onto the ram so that we can play and the rest streams into ram.
DP
Yes… definitely optional. Good idea to clarify that, Badmi.
I also like your suggestion, DP… Using RAM as a buffer should keep things sounding nice and smooth in most cases.
–K
fwiw the following 3dfx real-time streaming audio poc example uses the NativeFmod swig generated binding to FMOD.
I get a fatal error in the jvm closing the stream, but am not sure where this lies so while I track it down have sent the details to jerome, who is the NativeFmod developer.
