iOS - How to play a video with transparency?
(8 answers)
Closed 9 years ago.
I would like to play a video with a transparent background. The only thing is that all the information I found on the internet is "how to make the video background transparent", but the background of my video is already transparent, now I need to make the background of the player transparent. How do I do that? I tried this:
NSString *resourcePath = [[NSBundle mainBundle] pathForResource:#"New Project 5" ofType:#"m4v"];
NSLog(#"%#",resourcePath);
NSURL *url = [NSURL fileURLWithPath:resourcePath];
NSLog(#"%#",url);
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
moviePlayer.shouldAutoplay=YES;
moviePlayer.controlStyle = MPMovieControlStyleNone;
[moviePlayer setFullscreen:NO animated:YES];
[self.view addSubview:moviePlayer.view];
moviePlayer.view.frame = CGRectMake(200, 600, 400, 300);
[moviePlayer play];
moviePlayer.view.backgroundColor = [UIColor clearColor];
for(UIView *aSubView in moviePlayer.view.subviews) {
aSubView.backgroundColor = [UIColor clearColor];
}
But it doesn't work. It displays a black background.

Here is a link with a real solution to this problem playing-movies-with-an-alpha-channel-on-the-ipad. Her blog post is talking about video on the iPad, but the same library with alpha channel support also works on iPhone. It is also possible to encode to h.264 with alpha channel support using the method described in the blog post comments.
