Question

I try to play a video on the server with this code. I have a error.

//Play the video from server
    - (IBAction)playVideo:(id)sender;
    {
        NNSURL *url = [[NSURL alloc]initWithString: aVideo.urlVideo];
NSLog(@"URLVIDEO %@", url);
MPMoviePlayerController *VideoPlayer = [[MPMoviePlayerController alloc]initWithContentURL: url];
[VideoPlayer play];      
    }

//Console

URLVIDEO http://147.83.74.180/videos/low/ElTemps-index.m3u8
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Content URL must not be nil.'

aVideo.urlVideo is defined on the Video class and it gets a value when I parse an xml file

//Video.h
NSString urlVideo;

//XMLParser.m
    [aVideo setValue:currentElementValue forKey:elementName]; //here i add the string

If I do this I can play the video:

NSString *videoURL = @"http://147.83.74.180/videos/low/ElTemps-index.m3u8";
    MPMoviePlayerController *VideoPlayer = [[MPMoviePlayerController alloc]initWithContentURL:[NSURL URLWithString:videoURL]];

Answer 1

aVideo.urlVideo isn’t a valid URL string. It is the NSURL that is nil.
