[Live-devel] RTSP Streaming on iOS

[Viraj Mehta]

Hello All,

I was wondering if you folks can help me stream video which is available to me using RTSP.
I have compiled Live555 source code for iOS and integrated in my project.
After supplying the URL to the below code:

	session = [[RTSPClientSession alloc] initWithURL:[NSURL URLWithString:stringContainingURL]];
	[session setup];
	NSLog(@"getSDP: --> %@", [session getSDP]);
	NSArray *array =  [session getSubsessions];
	for (int i = 0; i < [array count]; i++) {
		RTSPSubsession *subsession = [array objectAtIndex:i]; 
        	[session setupSubsession:subsession useTCP:YES];
		subsession.delegate = self;
		[subsession increaseReceiveBufferTo:2000000];
		NSLog(@"[subsession getProtocolName] = %@", [subsession getProtocolName]);
		NSLog(@"[subsession getCodecName] = %@", [subsession getCodecName]);
		NSLog(@"[subsession getMediumName] = %@", [subsession getMediumName]);
	}
	[session play]; 
	NSLog(@"error: --> %@",[session getLastErrorString]);

I get the following log:

2012-01-06 19:06:18.857 Sample_Video[25829:207] getSDP: --> v=0

2012-01-06 19:06:19.500 Sample_Video[25829:207] presentationTime.tv_sec = 1325856979

Its my understanding that I am receiving the video frames correctly but I am unsure on how to proceed from here to display the video on the device.
Any prod in the right direction is much appreciated.
Thanks for your time guys.
