Playing videos in UIWebView broken in iOS4?

Question

I have an app that's worked since version 2.0 of the SDK where I create and add a UIWebView and then load the URL of an .mov to play a movie. Ever since the early version of the 4.0 beta up until the 4.0 GM this has stopped working. When I load a movie now I get the following error: :Plug-in handled load" and the movie never displays.

Is this a known issue? Am I doing something wrong in 4.0?

Answer 1

I figured this out. It appears to be an issue with iOS4 not being backward compatible with a UIWebView created with 'init' rather than 'initWithFrame'. In 2.0 - 3.1.3, you could only show video in a UIWebview as full screen. I think this is why it didn't matter if you called 'init' -- the movie player would kick in and go fullscreen. However, in 3.2 and higher you can now inline video in a UIWebView so you have to call initWithFrame and give it something like [[UIScreen mainScreen] bounds] so there's a visible view. Not quite sure if this is bull or not but seems to be the case.

Answer 2

Simply just ignore it. No harm in doing so.

if (![error.localizedDescription isEqualToString:@"Plug-in handled load"])

Answer 3

I got a situation of "this movie could not be played" when playing a video clip. This happened when recorder was just used. And this would NOT happen when player was just used.

Then I set audio session category to kAudioSessionCategory_AmbientSound after recorder finished.

This problem was solved after I did that.

At least in PhoneGap's ChildBrowser, the didFailLoadWithError method handles and displays this message. Simply don't display the error, problem solved, but in this specific case there are two 'done' buttons to press before you get back to the application.
