I’m using FMOD Ex 4.02.01 and MSVS 7.0 on a Windows XP Pro platform. I can play an MP3 I have just fine using the playstream example program, but in my own app, it just loops the first half-second of the stream continuously and then crashes if I try to stop playback. I’ve setup FMOD nearly identical to the way it’s done in the sample program, except for I have channels set to 32 and I start the stream paused so I can change its volume/frequency/pan etc.
Also, I have an array of ‘FMOD::Sound’s to have multiple streams, but on trying to load a second stream, I get the error FMOD_ERR_ALREADYLOCKED.
Any help on these issues would be grealy appreciated. Thanks!
BTW: I can playback samples with no problems at all.
Okay, I found out why it was looping the first half-second. For some reason I forgot to check to see if the stream was already playing before calling play in a program loop; thus, it was calling play repeatedly. I was trying to use the ‘Channel->isPlaying’ method, but it returns FMOD_ERR_INVALID_HANDLE if you try to use it before a call to ‘System->playSound’, so I had to use another method. The problem I’m having now is when I call ‘Channel->stop’ on the stream, it returns FMOD_ERR_INVALID_HANDLE for some odd reason.
Also, on the creation of multiple streams, the FMOD_ERR_ALREADYLOCKED error comes in the ‘System->createSound’ method when it tries to load the second stream.
I’m not using different threads for my program, and I don’t know what could cause memory curruptions.
Edit: Yet another issue… if I play a sample before playing the stream, the stream will only play the first half-second and then stop. However, if I start the stream first, then playing samples has no ill effects.
Sorry, I think my statement was misleading. What I meant was, when I call ‘Channel->stop’ on a channel that is playing the stream, the call returns FMOD_ERR_INVALID_HANDLE, and the stream continues to play.
Is there any situation you can think of that would cause ‘System->createSound’ to return FMOD_ERR_ALREADYLOCKED? Also what could cause a stream to stop after the first half-second after a sample is played. I don’t know why I’m having these problems and noone else is, but I could post my full source code for how I’m using FMOD if that would help.
Well, so far the only problem I’ve managed to get rid of is the stream that stops playing after a half-second if it starts playing after samples have been played. All I did was change the creation mode to include FMOD_HARDWARE instead of the default FMOD_SOFTWARE. I dunno why that would effect it, but it worked. I still haven’t figured out the problems with calls to ‘Channel->stop’ or the FMOD_ERR_ALREADYLOCKED for multiple stream loads.
I am calling ‘System::init’ with a channel count of 32.
