Trying to use playbin2 with filesink.

Hi Mike,

Well thanks for that.  I need to have a think about what to do next.

Regarding your other points:

Yeah, I noticed that just after I sent it.  Really I want lossless 
compression (maybe y4menc) and no licence problems.  I'm not really 
clear what muxing is, or if I even need to have it.

Ok, thanks.

It needs to be as near real-time as possible, so I hoped if I ran 
the file storage in a different thread it might speed up the 
camera-to-screen bit.  I have to say I don't notice any difference
Either way, so maybe it's redundent.

Anyway thanks for your help.

If you have any other thoughts about the above I'd like to hear
them.

Regards

Steve
