I’m trying to get streaming internet radio into our existing code but I’m having problems.

I’m using the event system with our own File IO routines via SetFileSystem. When I try to use CreateSound and pass in a URL our open callback is called and it tries to open is as a file and fails.

I see that CreateSound can have its own callback IO routines set, but I can’t see a way of forcing CreateSound to use Fmods built in routines (if SetFileSystem has been set).

If I do not use SetFileSystem the internet radio streams work fine, but none of my events work getEvent returns file not found. I think this is because the fsb files are failing to load, but that appears to be a internal process in FMod and there is no way to set IO callbacks for the event?.

I have found this post from 3 years ago thats seems to be same problem, but it doesn’t have any replies. :(

Is there any way of using the builtin internet streaming and have custom file IO routines for events?

You would be using a ‘programmer sound’ in the event you are trying to build I assume?
The programmer sound will then create a callback where you return a low level FMOD::Sound object to the event system. This is your internet stream
You don’t even have to override any file callbacks – fmod will stream from the internet for you if you pass the url into createStream.

If you want to use your own net functions, then use FMOD_CREATESOUNDEXINFO and just use the new file callbacks for that sound only. Everything else will use the standard file system.

Good news, I have a solution.

Your suggestion to use FMOD_CREATESOUNDEXINFO on System::CreateSound made me look at the structure again, and I found ‘ignoresetfilesystem’, setting it to one forces that particular sound to use the built in routines. This means you can use System::SetFileSystem to set custom IO callbacks but still create sounds using FMods built IO (in my case for FMods internet stream).

Thanks for the help. :)
