Bug 128402 – Implement DataCue for metadata cues

• Component: Media
• Status: RESOLVED FIXED

[Brendan Long]

See:

http://www.w3.org/html/wg/drafts/html/CR/embedded-content-0.html#datacue

This allows us to add binary metadata cues.

The implementation of .text leaves something to be desired, but I have no idea how to do content sniffing. For in-band DataCues, we could use a constructor that takes a String instead of an ArrayBuffer, but I wasn't sure if that should be added now.

This one should make JSDataCue build correctly for Mac WebKit.

Ick, that is a mouthful. Is it really worth the double cast so you can call the other form of toDataCue and not duplicate the ASSERT here?

Nit: I think it would be helpful to include the spec text here as a comment.

Added spec text to addCue(), duplicated the ASSERT in toDataCue() instead of doing two const_casts, and added DataCue to one more test -expected.txt file.

I'm not sure where to add JSDataCue or DataCue.idl. "git grep git grep TextTrackCue Source/WebCore/WebCore.vcxproj/" didn't show any JS* or *.idl files.

This might fix the Windows build? I added DataCue.h to another part of the project file.
