[tbb-dev] TBB and h.264 default configuration

Hi folks,

I have a simple question: why is that TBB has by default the option media.gstreamer as "false"? (At least in Linux). I need to have it "enabled" in order to watch videos on, say, Vimeo (which requires h.264). I know how to do this from about:config, but this makes me wonder whether it is safe to enable it and surf the web with TBB (I guess this is my real question).

Thanks a lot. Best, Col.
