after turning the compiler to clang(llvc)

I got this Internal Compiler error : segmentation fault

-(IBAction)clickedOpenMovie:(void)sender
{
    NSString *myString = [NSString stringWithFormat:@"http://localhost:1935/mystream/mystream.sdp"];

    NSURL *myURL = [NSURL URLWithString:myString];

   [self playMovieAtURL:myURL];

}

Answer 1

sooo yah the problem was that I didnt add the framework to my xcode project and the linked libraries were thusly not there. Thanks all for looking..

Answer 2

-(IBAction)clickedOpenMovie:(void)sender

That's wrong. void means no type, and you cannot pass an argument of no type to a function. That's probably what's getting you the error from cc1obj.

The correct signature for an action method is:

-(IBAction)clickedOpenMovie:(id)sender

id is the type of any Objective-C object.

NSString *myString = [NSString stringWithFormat:@"http://localhost:1935/mystream/mystream.sdp"];

This is both wrong, because that is not a format string, and pointless, because you already have the finished string there. Cut out the message and just assign the string directly to the variable:

NSString *myString = @"http://localhost:1935/mystream/mystream.sdp";

You should only use stringWithFormat: when you have a format string and some values you want spliced into it.
