Description Eric Carlson 2011-12-13 13:15:51 PST
When MediaPlayer::load is not passed the MIME type for a url, it uses the extension to looks one up in the type cache. The code that extracts the extension searches for a '.' from the end of the url, without consideration for whether the url has a fragment or query.

Would be better to call url.protocolIsData() since we have the URL.

Is this the only place in our code where we get the extension from a URL? If not, maybe they can share more code.

This include is not needed. All the header needs is a forward declaration of the KURL class.

>> Source/WebCore/platform/graphics/MediaPlayer.h:211
>> -    bool load(const String& url, const ContentType&);
>> +    bool load(const KURL& url, const ContentType&);

I agree with the style bot.
