Re: StreamingPlayer.zip

You'll need to download that separately.  From the article:


Note: The API needs an implementation of a thread safe Circular Byte Buffer. You can copy the implementation as CircularByteBuffer.java to rimx.media.streaming package and then compile the project. For an example, click here.

Re: StreamingPlayer.zip

Add the following method to CircularByteBuffer.java


* Increase the size of the buffer
public void resize(int bySize){
byte[] newBuffer = new byte[bySize];
int marked = marked();
int available = available();
if (markPosition <= writePosition){
// any space between the mark and
// the first write needs to be saved.
// In this case it is all in one piece.
int length = writePosition - markPosition;
System.arraycopy(buffer, markPosition, newBuffer, 0, length);
} else {
int length1 = buffer.length - markPosition;
System.arraycopy(buffer, markPosition, newBuffer, 0, length1);
int length2 = writePosition;
System.arraycopy(buffer, 0, newBuffer, length1, length2);
buffer = newBuffer;
markPosition = 0;
readPosition = marked;
writePosition = marked + available;
