Great! I'm not quite sure I understand all these changes yet, so I'm not going to flip the flags. I have a few comments though.

You can let this comment flow.

I'm not exactly sure why you want to only cache the total bytes sometimes...

> Source/WebCore/platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.h:203
> +            unsigned m_totalBytes;

This should probably be called m_cachedTotalBytes, because at first I read it like "The total bytes we have cached" and the name I suggested is less ambiguous.

Even better is if you could find a way to eliminate m_totalBytesCached entirely, perhaps by initializing  m_totalBytes to -1 (perhaps make it a long).

Assuming you don't do that...an unsigned seems an odd type to use for some number of bytes. Perhaps size_t would be better?
