> Source/WebCore/mediastream/MediaStream.cpp:41
> +void processTrackList(PassRefPtr<MediaStreamTrackList> prpTracks, String kind, MediaStreamSourceVector& sources, ExceptionCode& ec)

nit: this function should be marked static or placed in an anonymous namespace.
nit: String should be passed as |const String&|

> Source/WebCore/mediastream/MediaStream.cpp:44
> +    if (tracks.get()) {

nit: consider an early return if !tracks.get()

what is the reason for storing prpTracks as tracks?

> Source/WebKit/chromium/public/WebUserMediaClient.h:46
> +    virtual void requestUserMedia(const WebUserMediaRequest&, const WebVector<WebMediaStreamSource>&, const WebVector<WebMediaStreamSource>&) { }

nit: add parameter names for the new function?  it isn't always obvious which is the set of the audio tracks and which is the set of video tracks.

shouldn't the comment just be about declaring the first function as DEPRECATED?  the second function is the new one, right?

> Source/WebKit/chromium/public/WebUserMediaRequest.h:74
> +    WEBKIT_EXPORT void requestSucceeded(const WebVector<WebMediaStreamSource>&, const WebVector<WebMediaStreamSource>&);

same nit:  please name the parameters.  it is not clear otherwise which one is for audio and which one is for video.

> Source/WebKit/chromium/public/platform/WebMediaStreamDescriptor.h:59
> +    WEBKIT_EXPORT void initialize(const WebString& label, const WebVector<WebMediaStreamSource>&, const WebVector<WebMediaStreamSource>&);

same nit.

Fixed nit.

Don't think I understand your question. I need to store the PassRefPtr into a RefPtr so I can use it more than once.
