<pre>[EME] Add a CDMSession for MediaPlayerPrivateMediaSourceAVFObjC
https://bugs.webkit.org/show_bug.cgi?id=129166
Reviewed by Eric Carlson.
Add a new CDMSession, cerated by MediaPlayerPrivateMediaSourceAVFObjC allowing
media-source-backed media elements to play protected content.
Add a new CDMSessionMediaSourceAVFObjC class:
* platform/graphics/avfoundation/objc/CDMSessionMediaSourceAVFObjC.h: Added.
(WebCore::CDMSessionMediaSourceAVFObjC::~CDMSessionMediaSourceAVFObjC):
* platform/graphics/avfoundation/objc/CDMSessionMediaSourceAVFObjC.mm: Added.
(WebCore::CDMSessionMediaSourceAVFObjC::CDMSessionMediaSourceAVFObjC):
(WebCore::CDMSessionMediaSourceAVFObjC::generateKeyRequest): Do not actually generate a
key request until the certificate data has been added via update();
(WebCore::CDMSessionMediaSourceAVFObjC::releaseKeys): No-op.
(WebCore::CDMSessionMediaSourceAVFObjC::update): If no certificate data has yet been
added, assume the incoming message contains it.
* platform/graphics/avfoundation/objc/MediaPlayerPrivateMediaSourceAVFObjC.h:
* platform/graphics/avfoundation/objc/MediaPlayerPrivateMediaSourceAVFObjC.mm:
(WebCore::MediaPlayerPrivateMediaSourceAVFObjC::registerMediaEngine): Add supportsKeySystem.
(WebCore::keySystemIsSupported): Use "com.apple.fps.2_0" to distinguish from the not-media-source scheme.
(WebCore::MediaPlayerPrivateMediaSourceAVFObjC::supportsType): Check the keySystem type.
(WebCore::MediaPlayerPrivateMediaSourceAVFObjC::supportsKeySystem): Added.
(WebCore::MediaPlayerPrivateMediaSourceAVFObjC::createSession): Added, pass through to MediaSourcePrivate.
* platform/graphics/avfoundation/objc/MediaSourcePrivateAVFObjC.h:
* platform/graphics/avfoundation/objc/MediaSourcePrivateAVFObjC.mm:
(WebCore::MediaSourcePrivateAVFObjC::createSession): Added.
(WebCore::MediaSourcePrivateAVFObjC::sourceBufferKeyNeeded): Pass through to MediaPlayer.
* platform/graphics/avfoundation/objc/SourceBufferPrivateAVFObjC.h:
* platform/graphics/avfoundation/objc/SourceBufferPrivateAVFObjC.mm:
(-[WebAVStreamDataParserListener streamDataParser:didProvideContentKeyRequestInitializationData:forTrackID:]):
Added, pass through to SourceBufferPrivate.
(WebCore::SourceBufferPrivateAVFObjC::SourceBufferPrivateAVFObjC):
(WebCore::SourceBufferPrivateAVFObjC::didProvideContentKeyRequestInitializationDataForTrackID): Remember
which track is requesting the key, and pass the request to MediaSourcePrivate.
Add new files to the project.
* WebCore.xcodeproj/project.pbxproj:</pre>
