Getting blank white screen when presenting MPMoviePlayerViewController with no network connection - iphone

I am playing a media file present on the server. I purposely turned off the wifi connection in order to test the app. What I get is a blank screen.
What I want is to check before playing the video file is for internet connection. IF there is not connection, I dont want to play the video and display a alert message. How can I do so?
Can anyone help me on the same?
if ([[[UIDevice currentDevice] systemVersion ] doubleValue] >= 3.2) {
MPMoviePlayerViewController *mediaPlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:urlAddress]];
if (mediaPlayer) {
[self presentMoviePlayerViewControllerAnimated:mediaPlayer];
mediaPlayer.moviePlayer.movieSourceType = MPMovieSourceTypeFile ;
[mediaPlayer.moviePlayer play];
[mediaPlayer release];
}
}

iphone MediaPlayerController does not show the media player

HI,
I am developing an app which contains 3 tab view control. One each for audio, video and images.
When i select the video tab, I have all the items displayed in the table view format so that on selection of any cell, the video is shown.
Example.
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:url]] ;
[moviePlayer play];
}
The problem with this is though I am able to play the video I am unable to see the video and can hear only the audio.
In addition, if I were to close the app while the video is playing, and start it the app, the application crashes.
Can you please let me know how should I go ahead ?
After spending some more time, I have found out that for version above 3.2 one has to use MPMoviePlayerViewController.
The use of the same resolved the issue.
if ([[[UIDevice currentDevice] systemVersion ] doubleValue] >= 3.2) {
MPMoviePlayerViewController *mediaPlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:urlAddress]];
if (mediaPlayer) {
[self presentMoviePlayerViewControllerAnimated:mediaPlayer];
mediaPlayer.moviePlayer.movieSourceType = MPMovieSourceTypeFile ;
[mediaPlayer.moviePlayer play];
[mediaPlayer release];
}
}
Check out this technote from Apple:

To summarize, you need to add the movie player controller's view as a subview of your app's view.

MPMoviePlayerViewController quits unexpectedly

I'm trying to get videos to play from my server on the iPhone device. I'm using the following method to do so, however, it only works in the simulator; and on my iPhone 4. It doesn't work on iPhone 3G?
If I call this method on the iPhone 3G, it opens the video modal screen, starts to load the video, and then closes the modal screen abruptly. No errors are shown in the console.
The iPhone 3G has version 4.0 installed. My iPhone 4 has version 4.1.
Has anyone else experienced this?
-(IBAction)playMedia{
NSString* url = [self.data objectForKey:#"url"];
//initialize the movie player
self.moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:url]];
//show a background image while the user waits
moviePlayerViewController.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:#"background.png"]];
moviePlayerViewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
//show the movie
[self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];
[moviePlayerViewController release];
}
ok I got video to work on both iPhone 4 and iPhone 3G. Basically the issue was the file format. I was playing a .mov file. When I changed the format to .mp4, it now works on both devices. No change in code.
Hope this helps others with the same issue.
I'd do the above a little differently:
-(IBAction)playMedia{
NSString* url = [self.data objectForKey:#"url"];
//initialize the movie player
MPMoviePlayerViewController *tmpPlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:url]];
self.moviePlayerViewController = tmpPlayer;
//show a background image while the user waits
UIColor *tmpColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:#"background.png"]];
self.moviePlayerViewController.view.backgroundColor = tmpColor;
self.moviePlayerViewController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
//show the movie
[self presentMoviePlayerViewControllerAnimated:self.moviePlayerViewController];
[tmpPlayer release];
[tmpColor release];
}

Writing an app to stream video to iPhone

I'm interested in creating an iPhone app that can stream video from a central server, YouTube style. I was wondering if anyone has ever tried to do this before, what is the path of least resistant, existing APIs, etc? I really know nothing about how this is generally done. Would I be working with sockets? Just looking for some direction here. Thanks!
If you have the streaming server up and ready, it is quite easy to implement a video controller that pops up youtube-style.
NSString *videoURLString = #"http://path-to-iphone-compliant-video-stream";
NSURL *videoURL = [NSURL URLWithString:videoURLString];
MPMoviePlayerController moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
[moviePlayer prepareToPlay];
[moviePlayer play];
[self.view addSubview:moviePlayer.view];
You need to handle the controller that display the video player's view (which is self in this case).
In iOS 3.2+ MPMoviePlayerViewController make it even easier:
NSString *videoURLString = #"http://path-to-iphone-compliant-video-stream";
NSURL *videoURL = [NSURL URLWithString:videoURLString];
MPMoviePlayerViewController *moviePlayerView = [[[MPMoviePlayerViewController alloc] initWithContentURL:videoURL] autorelease];
[self presentMoviePlayerViewControllerAnimated:moviePlayerView];
presentMoviePlayerViewControllerAnimated is a MediaPlayer's additional method to FWViewController that you will find in iOS 3.2+ and it takes care of creating a view controller and pushing it on the stack, animating it with a slide-from-bottom animation, as in youtube.app.
Apple has a detailed article about setting up server side for media streaming:
https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/StreamingMediaGuide/Introduction/Introduction.html
and Best Practices Note:
https://developer.apple.com/library/content/technotes/tn2224/_index.html
Not only it contains info about streaming service architecture and tools used to build it but also has some requirements to such kind of service that must be fulfilled and references to live test streams.
Use this code to use low memory. On streaming video....
-(IBAction)playMovie:(NSURL *) theURL
{
NSURL *fileURL = theURL;
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.useApplicationAudioSession = NO;
moviePlayerController.fullscreen = YES;
[moviePlayerController play];
}
- (void)moviePlaybackComplete:(NSNotification *)notification
{
MPMoviePlayerController *moviePlayerController = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[moviePlayerController.view removeFromSuperview];
[moviePlayerController release];
}
QuickTime videos already stream to the phone. The path of least resistance would be to use the media player controller and point it to a streaming media file on a streaming server.
While the existing answers are good, if you need to use non HTTP streams (mms or rtmp for example) or non Apple supported audio / video codecs, things get a bit more complicated.
I'm not an expert myself, but I've been using this VideoStreaming SDK to solve those problems, and it makes customizing the client much easier (background streaming, pausing streams, etc). Might be worth a look if you have those requirements as well.
2018 answer You can use AVPlayerViewController since MPMoviePlayerController is deprecated since iOS 9
NSURL *url = [NSURL URLWithString:videoUrl];
_playerViewController = [[AVPlayerViewController alloc] init];
_playerViewController.player = [AVPlayer playerWithURL:url];
_playerViewController.player.volume = 1;
_playerViewController.showsPlaybackControls = YES;
_playerViewController.view.frame = CGRectMake(....);
[self.view addSubview:_playerViewController.view];

Loading Multiple Movies in iPhone MPMoviePlayerController

-(void)initAndPlayMovie:(NSURL *)movieURL
{
// Initialize a movie player object with the specified URL
MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
if (mp)
{
self.moviePlayer = mp;
[mp release];
[self.moviePlayer play];
}
}
Here, in above code, We can pass just one movie URL. Isn't it possible to pass multiple urls to it?
So, Movie Player will load second url after playing first one.
Is it possible? How can we do that?
Right now, when I try to pass other url, after finishing first one.
- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
[self initAndPlayMovie:secondURL];
}
The Device First change its orientation while loading and after loading Device again come back to landscape mode.
How to resolve this problem?
You might want to change the orientation by changing the statusBar orientation before you start playing videos and change it back after you are done with all.
[[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationLandscapeRight animated:YES];
You should be able to call setContentURL just as the first movie is about to close to change to another movie. Check endPlaybackTime and fire off your method to invoke setContentURL one second prior to the movie ending.

Embedded Video in a UIView with iPhone

I would like to write an app that downloads (or streams) a video (encoded as required) in a view. I dont want to use the MPVideoPlayer from the SDK as it opens the video in full screen. I would like to place another UIView (transparent) over the video so that my users can annotate over the video.
Anyone have any idea or can point me to some code that will play video in a UIView?
If you want to do this you will need to include your own (software) video decoder, which will not have access to the hardware acceleration on the system. Even if you can get it working with acceptable performance it will be a huge battery drain.
If you wish to play a video in portrait mode, I have solution for that.
If you think that -MPMovie Player can run under a view, according to me it's not possible.
MP Movie player will work as Apple has designed.
So, MP Movie player will always / almost run in full screen.
Solution for portrait mode.
#interface MPMoviePlayerController (extend)
-(void)setOrientation:(int)orientation animated:(BOOL)value;
#end
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieUR];
[moviePlayer setOrientation:UIDeviceOrientationPortrait animated:NO];
if (moviePlayer)
{
[self.moviePlayer play];
}
Hope that will help to you.
See, My question is very similar like yours.
playing video in custom size screen - view in iphone
Try this:
UIViewController *v = [[UIViewController alloc] init];
v.view.backgroundColor = [UIColor orangeColor];
NSString *path = [[NSBundle mainBundle] pathForResource:#"demo" ofType:#"mp4"];
if (![[NSFileManager defaultManager] fileExistsAtPath:path])
{
NSLog(#"cannot find %# in bundle or doctuments", path);
}
NSURL *url = [NSURL fileURLWithPath:path];
MoviePlayerViewController *mpvc = [[MoviePlayerViewController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:mpvc.moviePlayer];
mpvc.moviePlayer.fullscreen = NO;
[mpvc.moviePlayer setControlStyle:MPMovieControlStyleNone];
mpvc.moviePlayer.view.frame = CGRectMake(10, 100, 300, 300);
[v.view addSubview:mpvc.moviePlayer.view];
[mpvc.moviePlayer play];
[self presentModalViewController:v animated:YES];
[v release];
Maybe you should check the MediaPlayer's private headers, and simply add the video's view as your view's subview.
