Example of player for iOS

This player can be used to play any type of stream on Web Call Server

On the screenshot below an RTSP stream is being playing.

In the input fields

Work with code of the example

To analyze the code, let's take Player example, which can be downloaded with corresponding build 2.5.2.

View class for the main view of the application: ViewController (header file ViewController.h; implementation file  ViewController.m).

1. Import of API. code

#import <FPWCSApi2/FPWCSApi2.h>

2. Session creation.

FPWCSApi2 createSession code

The options include:

FPWCSApi2SessionOptions *options = [[FPWCSApi2SessionOptions alloc] init];
options.urlServer = _connectUrl.text;
options.appKey = @"defaultApp";
NSError *error;
FPWCSApi2Session *session = [FPWCSApi2 createSession:options error:&error];

3. Connection to the server

FPWCSApi2Session connect code

[session connect];

4. Receiving the event confirming successful connection.

ViewController onConnected code

On this event, ViewController playStream method is called to play stream

- (void)onConnected:(FPWCSApi2Session *)session {
    [self changeViewState:_remoteStreamName enabled:NO];
    [self playStream];
}

5. Stream playback.

FPWCSApi2Session createStream, FPWCSApi2Stream play code

Object with next stream options is passed to createStream method:

- (FPWCSApi2Stream *)playStream {
    FPWCSApi2Session *session = [FPWCSApi2 getSessions][0];
    FPWCSApi2StreamOptions *options = [[FPWCSApi2StreamOptions alloc] init];
    options.name = _remoteStreamName.text;
    options.display = _remoteDisplay;
    NSError *error;
    FPWCSApi2Stream *stream = [session createStream:options error:nil];
    ...
    if(![stream play:&error]) {
        UIAlertController * alert = [UIAlertController
                                     alertControllerWithTitle:@"Failed to play"
                                     message:error.localizedDescription
                                     preferredStyle:UIAlertControllerStyleAlert];
        
        UIAlertAction* okButton = [UIAlertAction
                                   actionWithTitle:@"Ok"
                                   style:UIAlertActionStyleDefault
                                   handler:^(UIAlertAction * action) {
                                       
                                   }];
        
        [alert addAction:okButton];
        [self presentViewController:alert animated:YES completion:nil];
    }
    return stream;
}

6. Disconnection.

FPWCSApi2Session disconnect code

- (void)startButton:(UIButton *)button {
    [self changeViewState:button enabled:NO];
    if ([button.titleLabel.text isEqualToString:@"STOP"]) {
        if ([FPWCSApi2 getSessions].count) {
            FPWCSApi2Session *session = [FPWCSApi2 getSessions][0];
            NSLog(@"Disconnect session with server %@", [session getServerUrl]);
            [session disconnect];
        } else {
            NSLog(@"Nothing to disconnect");
            [self onDisconnected];
        }
    } else {
        [self changeViewState:_connectUrl enabled:NO];
        [self connect];
    }
}

7. Receiving the event confirming successful disconnection.

ViewController onDisconnected code

- (void)onDisconnected {
    [self changeViewState:_connectUrl enabled:YES];
    [self onStopped];
}
