Shouldn't this be display:none, and then each port that wants to display it can override?

> Source/WebCore/html/shadow/MediaControlElements.h:283
> +    MediaControlOverlayPlayButtonElement(Document*);

All single-argument constructors should be marked "explicit" so the compiler doesn't try to implicitly create a MediaControlCromiumEnclosureElement from a Document*.

Is there any reason to not do this by subclassing MediaControlRootElementChromium instead of adding compile flags?

Again, is there any reason to not do this by subclassing?

Removed the ENABLE(MEDIA_OVERLAY_PLAY_BUTTON) flag, PTAL.

Done.

Refactored MediaControlRootElementChromium and added a subclass MediaControlRootElementChromiumAndroid to implement the functionality of  the overlay play button.

This class is full of static functions. So subclassing it does not help too much. I removed the "#if ENABLE(MEDIA_OVERLAY_PLAY_BUTTON)" in the file, the code will only be hit in the android port (called from RenderThemeChromiumAndroid)

This looks great with the minor nit noted. Thank you for taking the time to change your approach and then refactor, this is a huge improvement!

This should be unnecessary.

I thought you removed ENABLE(MEDIA_OVERLAY_PLAY_BUTTON) ?

Sorry, missed it. 
Yes, ENABLE(MEDIA_OVERLAY_PLAY_BUTTON) was removed.

Looks like your latest patch doesn't apply cleanly to top-of-tree.

Thanks.  R+ based on my (limited) understanding of this code and Eric's Comment #5.

This broke the Chromium-Linux canary compile.  Sample build log available at http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Linux%20%28dbg%29/builds/9510/steps/compile/logs/stdio .

The relevant info is:

out/Debug/../../third_party/gold/gold64: error: out/Debug/obj.target/third_party/WebKit/Source/WebCore/WebCore.gyp/libwebcore_html.a(out/Debug/obj.target/third_party/WebKit/Source/WebCore/WebCore.gyp/../../../../../webcore_html/third_party/WebKit/Source/WebCore/html/shadow/MediaControlRootElementChromiumAndroid.o): multiple definition of 'WebCore::MediaControls::create(WebCore::Document*)'
out/Debug/../../third_party/gold/gold64: out/Debug/obj.target/third_party/WebKit/Source/WebCore/WebCore.gyp/libwebcore_html.a(out/Debug/obj.target/third_party/WebKit/Source/WebCore/WebCore.gyp/../../../../../webcore_html/third_party/WebKit/Source/WebCore/html/shadow/MediaControlRootElementChromium.o): previous definition here

Looks to me like the newly-added MediaControlRootElementChromiumAndroid.cpp file is not getting properly excluded from the Linux build.

Rolling this out on bug 92572.

html/ happens to be one of the directory that *Android.cpp files are not excluded.  So that's why my android build works fine while the linux build is broken.

Updated the webcore.gyp file to exclude all the *Android.cpp files from html/ directory for non-android build.
