Rects have a ctor that set the values to 0.

I don't like this (see below).

Do these need to return bool in case the user agent wants to deny the request for fullscreen?

I really think we need to expose something through WebKit to allow the hosting application to make decisions about whether fullscreen video is allowed. Maybe it's just a preference at first?

Params should be const IntRect&, and be named so I know what they represent.
I'm not a big fan of feeding in the rects; what if the video is transformed, and we want to do a more cinematic animation to fullscreen?

> +    virtual void exitFullscreen(IntRect) {}

What is the rect?

Clarify the comment. Who's asking: the media player, or the browser?

Should you return something to indicate that you're already in fullscreen?

The asynchronous nature of this bothers me a bit. Should the MediaPlayer API expose the asynchronicity?

We also need to make sure that destroying the media element while in fullscreen, and during both transitions works.

Space after the for. Enumeration needs to work on Tiger.

Maybe we should determine which screen to show in here, rather than passing in the rect from outside?
We may be able to make better decisions, e.g. based on bit depth, size, primary, or even user-agent supplied preferences,
but should be able to choose the screen based on window position too.

Clarify comment to say the window might be offscreen.

Ditto.

Maybe wrap the contents of the file with #if ENABLE(VIDEO)? Same for other new files.

Need this?

Should probably remove these.

Should this set the movie on the movie view?

-request implies that refusal is possible, which is not the case here.

There's a macro like UNUSED_PARAM for this.

Use opaque black?

Assert that _fullscreenAnimation is nil.

This will probably need to change once we have HUD controls that should be keyboard navigable.

Should this be done via a delegate method, or just a method on the specific class of the window controller.

Capacity 3?

Assert that you dont' have a _fullscreenAnimation already.

WebCore style is to say 0.4, 5.0 etc.

No spaces after colons in Obj-C.

Return on new line.

Support Fullscreen for video element

 1622     IntRect elementRect(0,0,0,0);

There are style problems with that line, but the default constructor would do better anyway.

Except even better would be to early return like this:

if (!renderer())
    return IntRect();
return renderer()->view()->frameView()->contentsToScreen(renderer()->absoluteBoundingBoxRect());

Seems I could make this crash by getting "enterFullScreen or exitFullscreen()" called on a detached document.  page() goes through frame() if I remember correctly, and the document looses its frame when detached...

We could use a typedef for PlatformMovie instead of just void*:
 77     void* platformMovie() const;

const?
 146     IntRect screenRect();

Same problem with page():
virtual bool supportsFullscreen() const { return document() && document()->page()->chrome()->client()->supportsFullscreenForNode(this); }

If I had a click handler and detach the document during my handler but dont' prevent default, it should crash from the enterFullScreen() call:
525525 void MediaControlFullscreenButtonElement::defaultEventHandler(Event* event)

Extra spacE?
     BOOL _forceDisableAnimation;
 49 
 50 }

Should any of these be @private?  and what's // (retain) supposed to mean?  (I thought Obj-C 2.0 ... which maybe we don't use in WebCore... did auto-retaining or something for you? ;)

Seems we should pick one style or the other for .mm files:
55 - (void)setMediaElement:(WebCore::HTMLMediaElement*)mediaElement;
 56 - (WebCore::HTMLMediaElement*)mediaElement;
 57 
 58 - (void)enterFullscreen:(NSScreen *)screen;

What makes this weak pointer safe?
 - (void)setMediaElement:(WebCore::HTMLMediaElement*)mediaElement;
 104 {
 105     _mediaElement = mediaElement;

Why autorelease here?  Seems unnecessary to add it to the containing autorelease pool (or if it is, isn't that a bug?)  seems -release is what you want.

 - (void)clearFadeAnimation
 123 {
 124     [_fadeAnimation stopAnimation];
 125     [_fadeAnimation setWindow:nil];
 126     [_fadeAnimation autorelease];

Sad that this has to be 2-steps:
     [_backgroundFullscreenWindow release];
 141     _backgroundFullscreenWindow = nil;

Why do we need to self-retain?
 143     [self autorelease];  // From in exitFullscreen

Style:
 181     if (newRatio > originalRatio)
 182     {
 183         double newWidth = originalRatio * endFrame.size.height;

I would have used static inline functions to split up large functions like:
 170 - (void)enterFullscreen:(NSScreen *)screen;

 249     [self retain]; // Balanced in windowDidExitFullscreen
the comment ideally should explain "why"  :)

Most parts of WebKit prefer an early-return style:
 282     if ((self = [super initWithContentRect:contentRect styleMask:NSBorderlessWindowMask backing:bufferingType defer:flag])) {

I don't remember if AppKit has strong style to the contrary, but it seems checking !self would make more sense here.

Why not just use normal syntaxt?
 323         objc_msgSend([self windowController], _controllerActionOnAnimationEnd);

Style again:
44     if ((self = [super initWithContentRect:contentRect styleMask:NSBorderlessWindowMask backing:bufferingType defer:flag]))
 45     {

Style:
7     if (![[self window] isVisible]) {
 118         [[self window] setAlphaValue:0];
 119     }

I'm surprised we don't do more of the  184 - (void)windowDidLoad
 wiring in a nib?  Or maybe i'm over-remembering the power of nibs here.

Wouldn't Marc Piccerelli yell at you for this? ;)
0 - (void)updateVolume
 281 {
 282     [self willChangeValueForKey:@"volume"];
 283     [self didChangeValueForKey:@"volume"];
 284 }

Aren't there NSDateFormatters for this sort of thing?
 359 static NSString *timeToString(double time)

Ideally this patch would be smaller for easier review.   I can't promise that I've actually read it as closely as I really should have, but the above is enough for at least one more round.

(I won't be quoting all the part I agree with, or the obvious one. Thanks for pointing them out.)

Well, this shouldn't happen, because the enterFullscreen button has to result from user interaction, which shouldn't happen on detached document. I'll add an assert here.

After reading the rest of the review, you seem to highlight a special case where user interaction could happen with no document. I'll address that by adding proper check.

:) I don't think I am allowed to use Obj-C 2.0 here, so instead I am doing as if and marking ivar with // (retain).

What do you mean? NSScreen * is an objective C object pointer. The * has to be preceded by a space. WebCore::HTMLMediaElement is a C++ object. I think I am not mistaken here.

Right, after re-thinking release would be fine. Yet some other part of the code has to autorelease, because we may be processing callbacks from that object that may not be protected. (As you have noted below)

Because the animation that will be running doesn't retain the controller (ie - delegate). So if someone does 
[controller exitFullscreen];
[controller release];
This is bound to crash.

I'll recheck what other part of WebKit are doing.

I am not sure about that either. Nibs don't seem to be encouraged in WebKit.

Plus, the controls part of this nib are instantiated via WKSI. It can be done, but it felt ok and easier that way.

This is a bit controversial I know. Yet, having an ivar just to save all ivar, and synchronize them manually feels like a pain, and too much glue.

I would suggest to fix the KVO stuff :) Seriously, are you really against such a spread trick?

Thanks.

It was originally split in multiple, but was a pain to maintain, and you don't get to see all the stuff that will get used.

I was advised not to split it, and it actually make chance are each different file are pretty much doing independent stuff. So there is already a split here IMO.

Thanks for the review Eric!

Support Fullscreen for video element

I'm not sure:
const IntRect HTMLMediaElement::screenRect()
really makes any sense on the dom element.  I found the name "screenRect" confusing at first.  It's really absoluteRectForRenderer() or something, but that's a more general concept than just HTMLMediaElement, and thus makes it strange that it's on HTMLMediaElement.

Comment on attachment 33914 [details]
Support Fullscreen for video element

I don't see any reply about my earlier question about a typedef for PlatformMedia, but maybe I missed it?

Why the extra ()?
 55 @interface WebVideoFullscreenController () <WebVideoFullscreenHUDWindowControllerDelegate>
I didn't know empty category names were even allowed?

Which part is required:
 68     return @"No nib"; // Required to get -loadWindow to be called.
returning exactly "No nib" or returning a non-nil string?  The comment is unclear.

This must be a QT call getQTMovieViewClass(), cause "get" is not part of WebKit style.

If it's fullscreen, why would it want a shadow?
 88     [window setHasShadow:YES];
(for during the animation to full screen?)  Seems a comment might be needed here.

I thought there was some sort of fullscreen constant for levels like this:
 89     [window setLevel:NSPopUpMenuWindowLevel-1];
Someone who actually still works @ Apple would know better than I. :)

Why super, not self here?
93 - (WebVideoFullscreenWindow *)fullscreenWindow
 94 {
 95     return (WebVideoFullscreenWindow *)[super window];
 96 }

I'm surprised this isn't a _movieView method on the class:
 107         QTMovieView *movieView = (QTMovieView *)[[self window] contentView];

If we had a typedef PlatformMedia you might not need this cast. ;)
 108         [movieView setMovie:(QTMovie *)_mediaElement->platformMedia()];

No setDelegate call?
 153     _hudController.delegate = self;

Maybe Obj-C magically turns that into a setDelegate call... I'm kinda surprised that compiles even, since _hudController is clearly a pointer.

Seems:
constrainFrameToRatioOfFrame
really wants a "centerPoint" call on a rect, so that you don't have to compute it yourself.  Also sad that this is now at least the 3rd implementation of preserveAspectRatio logic (in some form) in WebCore.

I would have put this whole block in a separate function (but I tend to be very static-inline heavy).
 // Create a black window if needed
 198     if (!_backgroundFullscreenWindow) {
 
Style:
 else {
 206         [_backgroundFullscreenWindow setFrame:[screen frame] display:NO];
 207     }

Sad that this block:
242     if (!_forceDisableAnimation && [[self fullscreenWindow] isKeyWindow])
 243         _fadeAnimation = _backgroundFullscreenWindow ? [[WebWindowFadeAnimation alloc] initWithDuration:0.2 window:_backgroundFullscreenWindow initialAlpha:initialAlpha finalAlpha:0] : nil;
 244     else {
 245         // This will disable animation
 246         endFrame = NSZeroRect;
 247     }
 248 
 249     [[self fullscreenWindow] animateFromRect:[[self window] frame] toRect:endFrame withSubAnimation:_fadeAnimation controllerAction:@selector(windowDidExitFullscreen)];

is basically repeated twice.  Once to animate in, and once to animate out.  Maybe it could be abstracted into a function instead?

Did you learn if early-return was "sanctioned" here?
if ((self = [super initWithContentRect:contentRect styleMask:NSBorderlessWindowMask backing:bufferingType defer:flag])) {
It seems like it would be cleaner.

I'm surprised CoreAnimation doesn't take care of more of the "cancel existing animations an start animating in the other direction" code for you?  I thought that was part of the CA magic?
 336 - (void)animateFromRect:(NSRect)startRect toRect:(NSRect)endRect withSubAnimation:(NSAnimation *)subAnimation controllerAction:(SEL)controllerAction
Seems to be almost entirely about handling the "what if we're already animating" case.

I'm slightly suprised there no QTHudWindow to reuse here instead of writing one for WebKit.  I guess the QT ones are either private or not quite the right fit?

I'm surprised this needs to be conditional:
     if ([_timelineUpdateTimer isValid])
 110         [_timelineUpdateTimer invalidate];

I'm surprised we'd want to do anything if the window was already visible?
118     if (![window isVisible])
 119         [window setAlphaValue:0];

I would think a few simple accessors would take care of these nil clearings better than doing it manually at every callsite:
     [_area release];;
 144     _area = nil;

Different case here:
 174     return @"No Nib"; // So that -windowDidLoad gets called.
I guess the string contents don't matter then?

I would have probably created each of the UI elements in a separate constructor function, mostly because windowDidLoad is a huge function at this point.  But I'm not sure that it maters.  I hate how ugly UI code often is.

Seems strange to ask the delegate twice:
336     if (![_delegate mediaElement])
 337         return;
 338     WebCore::ExceptionCode e;
 339     [_delegate mediaElement]->setVolume(volume / [self maxVolume], e);

NSDateFormatters no right here?
 361 static NSString *timeToString(double time)

Still seems strange to ask the delegate more than once for mediaElement.  Not that it would change it's mind between calls... but it always scares me when asking delgates things. :)

Extra space:
 5462     HTMLMediaElement* videoElement = static_cast<HTMLMediaElement*> (node);

underlying:
 5466             // The backend may just warn us that the underlaying plaftormMovie()

Style:
     }
 5483     else

Cute:
 30 static const CGFloat slomoFactor = 10.;
But probably not the most readable to all our non-native english speakers. ;)

I'm surprised NSRect doesn't already do this?  CGRect and WebCore's FloatRect certainly do:
 37 static NSRect scaledRect(NSRect _initialFrame, NSRect _finalFrame, double factor)

Sigh.  Again FloatRect would do this cleaner:
     dist = squaredDistance(NSMakePoint(NSMaxX(_initialFrame), NSMinY(_initialFrame)), NSMakePoint(NSMaxX(_finalFrame), NSMinY(_finalFrame)));
Sad that NSRect doesn't have an easy topLeft() accessor...

What does additionalDuration actually do?  Seems like it's the duration needed to cover some specific distance... just not sure what that distance is named... (aka, I think the function needs a better name).

In general I think the change looks fine.  You probably want some current Apple UI Engineer to look at this instead of me though. :)

r-, mostly for unanswered questions from the previous review.

I am not that happy with this method as well, but I failed to see something sound that would not be more intrusive.

I could probably, in the mean time, use absoluteVideoRectForRenderer() on the HTMLVideoElement.

Do you prefer me to add absoluteRectForRenderer() on a super class?

Pierre.

I did define a ifdef for it, yet, I missed to propagate it down into the MediaPlayerPrivate.

This is a commonly(?) used way to define local method.

Returning a non nil string. I'll make the comment clearer.

Actually, it's how the dynamic linking defines its accessors, there is little I can do here apart using a #define. I don't plan to do it, is this really wanted?

Shadow is nicer when animating the fullscreen window. I'll add a comment.

Eh, I don't either :) AFAIK, there is no better way to do this kind of stuff. We really want to be on top of the Menu and Dock here. I could burry that in a constant for now.

Ok.

Right. This looks ugly.

I'll remove the cast. Note, I now have typedef void * PlatformMedia; This is actually media player and platform specific. For instance if we have a ffmpeg backend on Mac OS this wouldn't be a QTMovie. I should probably have some kind of better abstraction here. But for now, this would seem over-engineered.

This is Obj-C 2.0. I'll have to remove it.

Oh, I forgot about that. Yes, I checked, and I have to early return.

We are not using Core Animation, but NSAnimation, and AFAIK we really have to do that work ourselves.

Right, there is no QTHUDWindow to reuse.

If the window is already visible we want to animate the fadeIn from its current value to 1.
If the window is not visible, we want to:
1- set its alpha value to 0
2- show it
3- animate its alpha value to 1

So yes, we don't want to do anything if the window was already visible.

I could do it. But I am not sure if it wouldn't add more useless glue code. At least now, the ugly code is constrained to one function :)

I am by no way an expert of NSFormatters, but I don't think we can do what we want without subclassing. (We want 00:00 but 1:00:00 as well. )

I can't find it for CGRect. Do you have the name of the function. Using WebCore's FloatRect here is probably not really appropriate, right?

Right, I'll try to come up with a better name.

Thanks for the review!

Well, it seems that I can't reuse any of those. I also don't see what I would do with a centerPoint.

I didn't do it. I don't think it adds anything valuable, as this is common Cocoa practice. It won't also be magically thread safe or anything. I could add it though if style requires it :)

I think this should not enter fullscreen if renderer() is null.

I think this would be better as a union with a type flag.

I don't like this hack. Why do you go through the window nib-loading path, instead of just using -initWithWindow: ?

We don't normally use #pragma marks.

Corresponding header should come first, and the rest should be alphabetical.

So the HUD controls can't be operated via the keyboard? That sounds bad. What's accessibility like for those controls?

This looks weird. I think you should name the category 'Private' or something.

Why are you firing the timer right away?

Do these binding work on all OSes we have to support?

This violates the will/did change contract for bindings: 'willChange' should be called before the volume actually changes. If you can't do it correctly, maybe don't use bindings?

I don't think so because we need to support multiple backend at runtime. Am I mistaken?

We want to update the time right away. I'll add a comment.

Hum, I thought it would be more understandable with cos. I'll switch to a third order cubic bezier since it's lighter.

Thanks Simon! :)

Pierre is a committer, so I won't set cq+.  He could do it himself, except that the email address I see in
http://trac.webkit.org/browser/trunk/WebKitTools/Scripts/modules/committers.py
is not the one matching this bug.  So I expect that if he set commit-queue+ it would be rejected by the commit queue as an unknown committer.

You've created a retain cycle here (the timer retains its target). That's OK, because you explicitly call -unscheduleTimeUpdate before destroying the window, but I'd like to see a comment that mentions this.

We don't normally use comma-separated lists for multiple instance variable declarations. Please put one per line.

Where does HAVE_WINDOWSETSCALEDFRAME come from? I don't see it defined anywhere.

This patch has been waiting to land for a month.  Curious what's the status?

[Simon Fraser (smfr)]

I'm working on landing it. It needs some tweaking.
