Re: [Linphone-developers] linphone blackberry error 523 on device

Dear Aleksei,

I'm trying to investigate the problem in the RecvStream.java class.

I have fixed the playerupdate() method, the states of the player are
represented as Strings and so they have to be compared using equals()
instead of ==.

Once fixed I have obtained that player at 30 secs of normal call
enters in the PlayerListener.ERROR state with EventData code -5 that
is an unspecified error.
(http://supportforums.blackberry.com/t5/Java-Development/PlayerListener-ERROR-eventData-is-5-But-PlayerListener-ERROR/td-p/464383)

As posted by Izrdus in the link above, he has idenitifed the player
error problem as follows:

"I had a problem with my bookkeeping when the offset approaches length
in buffer javax.microedition.media.protocol.SourceStream.read(byte[],
int, int). Basically after 58000 bytes the audio would become
corrupted, causing the player to raise an error."

What do you about the Izrdus' solution?

I found an official code snippet from BlackBerry
(http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How_To_-_Support_streaming_audio_to_the_media_application.html?nodeid=1369914&vernum=0)
explaining how to use the SourceStream as source for a Player. In that
snippet the Thread.sleep() is used with a delay of 100ms so I think
that sleeping 20ms for collecting more data should not be the problem.

Cheers
