Bug 111934 – Caption menu does not include in-band captions

• Component: Media
• Status: CLOSED FIXED

[Chris Petersen]

In Full screen video mode, balloon icon appears on toolbar but is non functional. I'm noticing this icon on toolbar with NB r145321. Perhaps this is work in progress but just noticed it.

1) Launch NB r145321
2) Go to http://www.apple.com/ipad-mini/overview/. Click on Watch This Video
3) After movie starts to play, click on full screen icon to enter full screen video mode
4) After entering full screen mode, notice the "balloon" icon appearing on toolbar ( to the left of full screen icon )
5) Clicking this balloon icon on the toolbar doesn't appears to do anything ( at least to me )

Looks good generally, but I've got reservations about m_legacyWEbKitClosedCaptionsVisible.  See below.

Oops.

> Source/WebCore/html/HTMLMediaElement.cpp:846
> +    m_pendingActionFlags &= ~LoadMediaResource;

I know exactly what this does, but in the past I've gotten review comments where this construct was too confusing.  We should make a CLEAR_FLAG() and SET_FLAG() macro/inline that does this.

> Source/WebCore/html/HTMLMediaElement.cpp:4457

>      setClosedCaptionsVisible(visible);

This is weird.  I assume that m_haveVisibleTextTrack being set is a side effect of setClosedCaptionsVisible?

> Source/WebCore/html/HTMLMediaElement.cpp:4462

> +    return m_legacyWebKitClosedCaptionsVisible;

So you can call setWebkitClosedCaptionsVisible(TRUE) and have webkitClosedCaptionsVisible() immediately return FALSE?  That's odd.

If webkitClosedCaptionsVisible() is real being used as a "legacyOverride" can we rename it (or add a new function) "legacyClosedCaptionsShouldOverrideVisibility()" or something?

> Source/WebCore/platform/graphics/avfoundation/InbandTextTrackPrivateAVF.h:66
> +    virtual bool isLegacyCCTrack() const = 0;

Since there's already a isClosedCaptions(), this should be "isLegacyClosedCaptions()" or "isLegacyClosedCaptionsTrack()".

> Source/WebCore/platform/graphics/avfoundation/objc/InbandTextTrackPrivateLegacyAVFObjC.h:59

Ditto.

> Source/WebCore/platform/graphics/avfoundation/objc/MediaPlayerPrivateAVFoundationObjC.h:179
> +    void processLegacyCCTracks();

Same thing, expand CC -> ClosedCaption.

Yes, webkitClosedCaptionsVisible is meant to return true only if closed captions are visible, which can only be true if the file actually has a caption track. This has always been the case, media-captions.html tests this.

"webkitClosedCaptionsVisible" is web facing so we can't really change it.
