Subject: Leaking 4 sockets per file played.
Date: Thu, Oct 9, 2014 10:02 AM

Thanks for the suggestion of running things under valgrind. Since I last
posted, we've learned a few more things:

1) We can leak sockets when just running from the command line.
2) We only leak sockets when decodebin decides to use our patched versions
of gst-vaapi to decode files. (which we are now checking to see how it
handles sockets).
3) Valgrind seems to implicate gst_video_filter_propose_allocation as it
always seems to create a new buffer pool for each video file, but I'm
wondering if vaapi could somehow be causing this with malformed queries?
