Default BlackBerry Media Player

Please Login to Remove!


I was trying to play a RTSP stream from a streaming server over BlackBerry native media player. What i observed here is that BlackBerry Media Player opens RTP connection on TCP instead of UDP.

Do they have specific reason using TCP connection for RTP? Also is their a way we can force it to open a connection on UDP?

Thanks in advance.

Cell companys do not want resends of data. The use of TCP allows validated data for each packet. UDP is also different from TCP in that it doesn't provide any sort of guarantee that the receiver will receive packets in the right order; in fact, there's no guarantee that the packets will arrive at all. All that is guaranteed is that the packet's contents, if they arrive, will arrive exactly as sent, without data corruption.

Why do you care?
