GST_DEBUG: How to save logs in a separate file for a thread inside an
application

I am running a sample program of gstreamer which is being called from a
C++ application as a thread. Have set the GST_DEBUG=*:5 level to capture
all the possible scenarios.
The application also prints lots and lots of logs on stdout and the
gstreamer thread also does the same( the level 5 adds to the misery).
Question -- Is there a way to separate out the log printing of gstreamer
thread in a file with the given debug level ?
