GStreamer logging

[Ian Davidson]

I have been looking for a list of the Environment Variables which 
GStreamer uses.  I have not found such a list - all I have found is 
occasional mention of variables you might want to use.

Specifically, I notice that when you turn on logging, you tend to get a 
roomful of data.  I am aware that that I can redirect the output from 
STDOUT to a file - but I think I have seen mention of an environment 
variable to cause the logs to go to a specific folder.

Did I imagine such a variable?  If not, what is it and where is it 
described?

Thanks

Ian
