Transcoding and then playing the converted audio data

Question

I want to convert a wav file (in form of a byte array) from one encoding to another using Processor, and then play the converted result (in form of a byte array).
On a high level, I know I need to create a PullBufferDataSource as input, create a Processor using Manager and the PullBufferDataSource, program the processor, get the output DataSource, which is of type RawBufferMux$RawBufferDataSource.
My question is:
a. How do I play the RawBufferDataSource object using a Player object? or I shouldn't end up with a RawBufferDataSource object?
b. I noticed that Player and Processor classes perform their operations using multiple threads. How do I know what operations are always done in a different thread? Is there any documentation regarding this?
Thanks.

Answer 1

a. How do I play the RawBufferDataSource object using a Player object? or I shouldn't end up with a RawBufferDataSource object?Ummmm, you should just be able to hand it to a Player object.
Player pl = Manager.createPlayer(proc.getDataOutput());If that doesn't work, then you probably havn't set the format object of your input DataSource correctly.
b. I noticed that Player and Processor classes perform their operations using multiple threads. How do I know what operations are always done in a different thread? Is there any documentation regarding this?Why do you need to know?
And no, I don't think there's any documentation on it...
