i load a local html file into an ipad application:
NSURL *baseURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
NSString *path = [[NSBundle mainBundle] pathForResource:@"lieferant1" ofType:@"html"];
NSString *content = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
[webView loadHTMLString:content baseURL:baseURL];
the webpage gets displayed, content of my html file:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>

<video>
<source src="banane.m4v">
</video>
</p>
so, banane.m4v is in my root, just in some groups, but not in real directories.
but the video section in my webview keeps black. no video gets loaded. i uploaded my html file and my .m4v video to my webserver to check if its not encoded properly, but everything works fine, surfing the html file with my ipad.
some ideas whats wrong?
oh my god
<video controls>
<source src="banane.m4v">
</video>
where controls is the magic word.
:X
I may be wrong (or silly) but, did you try file:///banane.m4v (Add the extra '/' for root)
For everyone that experiences a crossed out play symbol, When you drag your movie-files (mp4's work as well, just make sure the codec is okay - easiest way is to export for iPhone with QuickTime) a dialog appears. Make sure you tick your app under "add to targets".
Or if you already copied your video into the project, if you click it in Xcode's file browser, you'll have an option on the right-hand side to select targets.
You need to set the allowsInlineMediaPlayback property on the UIWebView:
[webView setAllowsInlineMediaPlayback:YES];
