Hello :)

I'm currently working on an audio library, and have run into a problem.  Everything works fine, except that it seems that it's recommended to use openStream(), so I have a line like this in my code to access the location of the file:

in = AudioSystem.getAudioInputStream(libraryname.parent.openStream(filename));

I was previously using sketchPath to form a path to locate the audio files in the data directory but I tried switching over to openStream so that exporting would work, but it seems openStream does something with "mark" and/or "reset", which is incompatible with some of the audio streams my library is working with, so they fail to play.

Specifically, I get the following error in the PDE console, when I use openStream():
java.io.IOException: mark/reset not supported at java.io.InputStream.reset(Unknown Source)

Just wondering if there is a recommended course of action in this case?

One other thing I noticed:

When I export to app the process locks my computer up at 100% cpu usage for about 2 minutes when I have about 4mb of audio files in the data dir.  It eventually finishes but I would think the process would only take a second.  It could easily be something I'm doing wrong.  (I have speedy computer so that shouldn't be the bottleneck, unless I misunderstand the process behind export to app).

Anyway, thank you!

Hi Fry, thanks for the response.

About the openStream stuff, yeah, I'm going to look into it.  I wouldn't have posted if I didn't feel something weird was happening, but it still could very easily be my mistake.

The reason I posted was this method of opening a stream works fine with all of my audio types:

file = new File(playa.parent.sketchPath + File.separator + "data", fnp5);  // fnp5 is a String ("sound.wav")
in = AudioSystem.getAudioInputStream(file);

But this method causes the PDE console to spit out a mark/reset not supported error and not play certain audio:
in = AudioSystem.getAudioInputStream(mylib.parent.openStream(fnp5));

I'll look into getResourceStream, as that could be the culprit.  Assuming a situation where I can't use openStream(), is there another recommended way to access a file for streaming in a library so that it works from the PDE as well as when exported to application?

About that second issue -- it's not the performance of my library that hangs (it is a threaded library).  It's when, within the PDE, I do File->Export Application.  That process pins my CPU to 100% and locks up my computer for 2-3 minutes while exporting the application (on the windows platform).  It eventually finishes and I can browse the three application directories it creates.  I mentioned the 4mb of audio files in the sketch's "data" dir because I'm not sure if they are a factor in it taking so long to run the "export application" process.

Thanks again!
