Trying to use QTMovie + QTMovieView on main thread, it plays ok, but i can not return from video to OpenGL.
Looks like QTKit locks display link somewhere.

I'm just adding QTMovieView as a subview to OpenGLView (with setWantsLayer: YES), stopAnimation cocos2d and start playing a video from mainThread.
After videos ends (i use QTMovie end NSNotification) - i removeFromSuperView QTMovieView and startAnimation. But nothing is renderred and if i resize the window - i got only junk.

Any ideas, how to solve this or any other methods play video on Mac?

Hi! Have you figured this problem out? I have the same issue. I am using QTMovie and QTMovieView to play a video. I am adding QTMovieView to CCDirectorMac's openglView and then calling removeFromSuperview on the movieView once the video finishes. The movieView is visibly removed but I cannot interact with any of the cocos2d objects of the previous view.

Also, when the video is first displayed, the control bar at the bottom will not respond to mouse clicks. If I click the top bar and move the window the control bar is clickable and works as expected. It seems the view loses focus once added to the opengl view and I cannot figure out how to correct this (I have already tried the MovieView functions 'lockFocus' and 'unlockFocus').

Yes, here's the solution:

It plays video using all space of cocos view. Resizeable, but i didn't implemented toggleFullscreen: support yet.
You may cancel playing video by pressing a key or clicking a mouse button.

Thank you for the quick replay and thanks for the example code! I'm having a hard time compiling it because I seem to locate GameDirector.h or VideoPlayer.h. Do I need to add a certain framework to my project to get these headers?

Thank you for you contribution, just remember it might be an idea to give an example on how to use the files that you have shared.

Thanks for notifying me about this topic, mrTortex.
I will share universal video player later on GitHub with examples, but i don't have enough time for this now.

GameDirector is my own class, that i use in iTraceur for all game logics, so you don't need it.
In a fact it must not be included in VideoPlayer - i should use simple delegate with protocol for that.

VideoPlayer tries to play video from Caches folder and from Resources. It wouldn't do anything if file will not be found.

Here's the same sources with iOS implementation:
http://dl.getdropbox.com/u/1765875/UniversalVideoPlayer.zip

Here's some methods of GameDirector, that use VideoPlayer:
```
- (void) startPlayingVideoWithFile: (NSString *) movieFileName
{
#ifdef __MAC_OS_X_VERSION_MAX_ALLOWED
	[  self performSelectorOnMainThread: @selector(playMovieWithFile:)
							 withObject: movieFileName
						  waitUntilDone: NO  ];
#elif defined(__IPHONE_OS_VERSION_MAX_ALLOWED)
	[VideoPlayer playMovieWithFile: movieFileName];
#endif

}

#pragma mark Movie PLayer Callbacks
- (void) movieStartsPlaying
{
    [self pause]; //< includes [[CCDirector sharedDirector] pause]; but i think it's not important
#ifdef __MAC_OS_X_VERSION_MAX_ALLOWED
	[ [CCDirector sharedDirector] stopAnimation];
	//<DANGER: without it you may experience crashes
#endif
}

- (void) moviePlaybackFinished
{
	[[CCDirector sharedDirector] startAnimation];
#ifdef __MAC_OS_X_VERSION_MAX_ALLOWED
	[[[CCDirector sharedDirector] openGLView] setNeedsDisplay:YES]; //< do we need this really?!
#endif

	[self resume]; //< includes [[CCDirector sharedDirector] resume]; but i think it's not important

}
```
BTW it uses _wideKeyDelegate in MacGLView, that helps cancel playing video by pressing a key. It's not a part of Cocos2D, so you can get it in iTraceur's cocos2D branch: https://github.com/psineur/cocos2d-iphone/tree/iTraceur

This branch was started from 0.99.5-rc0 (last commit with comment: "Bye Bye" by Riqardo )

Still don't know how i will share video player in the future, as a single project or as a part of Cocos2D iTraceur branch, but probably it will be somewhere in my repos: https://github.com/psineur/

Thanks for this, I'll give it a try tomorrow. Left my code elsewhere so I can't try it now.

So, using this method we can place a QT Movie onto a layer, in a similar way to placing a simple image? If so, I salute you and promise if we ever meet to buy you a drink or nine. :)

No, this will not place QTMovie onto a layer. This will add view playing video right on the glView.
So if we meet i will stay thirsty ;)

Ok, that's the route I've been failing to make work recently :-). The video plays, you can hear it, but you can't see it. And the view is always detached, so I'm excited to try this out :-)

Thanks again. Beers in summer :D

Hello.

OK, I've imported these files into my project, and have removed all your GameDirector code and replaced it with my CCDirectorMac code. I've changed videoplayer to videoplayerImplMac and it compiles fine, but with warnings:

[self pause] and [self resume] methods are not found.

and [cancelPlaying] is not found also.

Actually running through each file they all have a ton of warnings on them. I'll fiddle some more :)

Hello,

I have got the VideoPlayer to work partially on mac:

Replace:

[[GameDirector sharedGameDirector] movieStartsPlaying];

by:

[[CCDirector sharedDirector] pause];
[[CCDirector sharedDirector] stopAnimation];

And replace:

[ [GameDirector sharedGameDirector] movieWatchedTillTheEnd ];
[ [GameDirector sharedGameDirector] moviePlaybackFinished];

by:

[[CCDirector sharedDirector] resume];
[[CCDirector sharedDirector] startAnimation];

I have also had to comment the following lines:

[MacGLView setWideKeyboardDelegate: [self.videoViewController view]];

otherwise the appo crashed and

[[self.videoViewController view] setFrame: [windowContentView bounds]];

otherwise the app freezes when the video is launched.

The last line being an issue since removing it the video no longer plays full screen and is not centred.

I have tried setting manually the frame size but it still freeze.

Hello, guys!

I'm very sorry about lack of documentation - i worked on iTraceur 1.3
I need to prepare screenshots and upload it, and after this i will spent some time on VideoPlayer, so please, feel free to comment and ask for anything related.

I just uploaded VideoPlayer with demos on GitHub: https://github.com/psineur/CCVideoPlayer
It includes both Mac & iOS projects.

There's a lack of documentation, but i used Cocos2D 1.0 templates as a start platform and existing VideoPlayer, that i shared here before. After this i made some commits, they should be pretty self-explanatory how to use VideoPlayer.

Sorry about possible mistakes in text, i'm not a native english speaker and very sleepy now.
Hope this will help. Feel free to comment, ask here, or on GitHub. If anyone would like to prepare Good formatted readme for VideoPlayer - i would like to apply your pull request.

Thanks! But I don't drink alcohol and don't have a paypal, that can receive payments, lol :)
But there should be a cute Donate button on cocos2d-iPhone.org - send your love there, and I'll be happy ;)

While the subject is at hand, I had to disable enabling or disabling full screen mode while the video plays because going full screen or leaving it while the video was playing caused big problems.

Also I do not know if this a problem with Cocos2d or the video player but after I play a video I sometimes, but not that often, have video memory leakage on the Cocos2d Sprites.

Here is an example of what I mean:

This is the worst case I have seen, sometimes there is only a Sprite or a Label replaced by black.

Yeah, this is a known bug.
Do you use last version of cocos2d, where one MacGLView is shared for both fullscreen & windowed mode? Maybe updating cocos will fix this, but anyway - CCVideoPlayer does not support toggle fullscreen, while playing, so i have disabled it too.

Feel free to open an issue on GitHub!

I am using cocos2d v1.0.0-rc, according to the changelist the MacGLView handling has not changed in the RC2 so updating should not solve the problem.

But having to disable full screen before videos and reactivating afterwards does not bother me much, it is the video artefacts that bothers me the most.

They disappear after the following scene is loaded, so I will see if I can work around the issue by using an intermediate scene for loading scenes after videos.

That's really strange and i dont think any inside of cocos2d manupulations will help, cause this looks like GLView and QTMovieView problems.

Try to use MainMenu.xib from CCVideoPlayer example.
MacGLView also must have wantsCoreAnimationLayer enabled, but i think it is set in the VideoPlayerMacImpl code.

Anyway, the fastest way for you to solve this problem is to do following:
1) Check that CCVideoPlayer-mac works fine - i mean it should work fine - let me know if it doesn't
2) Change video to yours in CCVIdeoPlayer and check that there's no issue due to video format
3) Try to build your project on the base of CCVideoPlayer-mac, grab anything related from example project to yours (CustomVideoView.nib, MainMenu.xib, cocos2d sources (it's 1.0, but i don't remember beta, rc, or just develop branch after 0.99.5 ))

Also if you can attach video of how this problem looks like - that can help me to get what's going on.
In video do some resizing of window please, when problem is in place - i remember i see something like this, when i initialized QTMovie wrong, but if you have it playing and only after this issues occurs - the only think i can think about is that QTMovieView isn't removed from parentView, but it should.

I noticed that you have update your source on GitHub, so I updated my project with your latest revision.

After trying to reproduce the bug at least 100 times I gave up, hoping it was resolved but this afternoon it occurred a few time again.

Now I am seeing if I can reproduce the bug in your sample project then I will try all your recommendations.

Thank you very much for your help.

Moved this topic to Extensions sub-forum.

CCVideoPlayer will be now available on the cocos2d-iphone-extensions repo, and all further development will go there.

Hello everyone,

Just a little warning to say that my Mac App was rejected for disabling full screen toggle while playing a video.

Has the issue with entering and exiting full screen mode while a video is playing been fixed since?

Posted 11 months ago #

@Jonathan, wow that's bad.

Not fixed yet, but i'm gonna try to solve it in 0.1.2: https://github.com/cocos2d/cocos2d-iphone-extensions/issues/31
Probably simple reattach needed, so if you'll fix it - please comment in that issue, or send a pull request. ;)

Thanks!

Thanks, you were right reattaching the view fixed the issue.

Here is what I did (I do not have a github account so I am posting it here):

In CCVideoPlayerImplMac.m I added:

- (void) reAttachView
{	

	[[self.videoViewController view] removeFromSuperview];

	NSView *windowContentView = [self.retainedView superview];
	[windowContentView addSubview:[self.videoViewController view]];
	[[self.videoViewController view] setFrame: [windowContentView bounds]];

}

In CCVideoPlayer.m :

#elif defined(__MAC_OS_X_VERSION_MAX_ALLOWED)

+ (void) reAttachView
{
    [_impl reAttachView];
}

#endif

(just after + (void) updateOrientationWithOrientation: to keep the platform specific code together)

And in my App delegate I modified toggleFullScreen :

- (IBAction)toggleFullScreen: (id)sender
{

	CCDirectorMac *director = (CCDirectorMac*) [CCDirector sharedDirector];
	[director setFullScreen: ! [director isFullScreen] ];

	//only reattach view if video is playing
	if ([SingletonGameState sharedGameStateInstance].videoPlaying) {
		[VideoPlayer reAttachView];
	}		

}

Also if it could be of any use I have implemented a "no skip" function to the video player that you can set if you do not want the user to skip the video for any given reason. It is not very complicated but I could also post what I have done if you want.

Thanks! Merged into develop branch: https://github.com/cocos2d/cocos2d-iphone-extensions/commit/2eac6d7220b9aea69107e7a2999bc3fe5fd5c1f0

Can you provide me detailed info to mention you in AUTHORS?
Firstname, Lastname, twitter & site are most common form. Right now i just added your nickname & link to your profile on cocos2d forums.

BTW, there's some changes in CCVideoPlayer in the develop branch:
1. Multiple finished callbacks avoided.
2. Delegate methods called from main thread.

This can fix rare issues, that you had before. Let me now if there's something still or again broken.

Also [CCVideoPlayer isPlaying] can be used instead of your own [SingletonGameState sharedGameStateInstance].videoPlaying.

If anyone can test CCVideoPlayer from develop - let me know how it works.
Thanks!

@Jonathan noSkip could be included to CCVideoPlayer, but it should leave the way to programmatically cancel video playback, disabling only skiping by touch/key/mouse.

Ok here is what I have done for the noSkip feature:

In CCVideoPlayer.h add:

+ (void) setNoSkip:(BOOL)value;

In CCVideoPlayer.m add:

+ (void) setNoSkip:(BOOL)value
{
    [_impl setNoSkip:value];
}

In CCVideoPlayerImplMac.h add:

BOOL noSkip;

and

- (void) setNoSkip:(BOOL)value;
- (void) userCancelPlaying;

In CCVideoPlayerImplMac.m add:

- (void) setNoSkip:(BOOL)value;
{
    noSkip=value;
}

- (void) userCancelPlaying
{
	if (!noSkip) {
		[self movieFinishedCallback: nil];
	}
}

In MyMovieView.m :

replace (x 4)

[CCVideoPlayer cancelPlaying];

[CCVideoPlayer userCancelPlaying];

In CCVideoPlayerImpliOS.h add:

BOOL noSkip;

and

- (void) setNoSkip:(BOOL)value;
- (void) userCancelPlaying;

in CCVideoPlayerImpliOS.m add:

- (void) userCancelPlaying
{
	if (!noSkip) {
		[self cancelPlaying];
	}
}

- (void) setNoSkip:(BOOL)value;
{
    noSkip=value;
}

In videoOverlayView.m :

replace

[CCVideoPlayer cancelPlaying];

[CCVideoPlayer userCancelPlaying];

[MAC] Anybody plays video somehow?
