During normal operation hlsdemux is leaking memory. On the embedded device that I am developing for, this causes gstreamer to die after about 15 minutes of 1.5mbps video. Checking with valgrind on a Linux desktop I can see a "possibly lost" of several MB of memory that it is allocated in hlsdemux.

The problem is that gst_hls_demux_get_next_fragment function calls gst_fragment_get_buffer which increments the reference count on the buffer but gst_hls_demux_get_next_fragment never calls unref on the buffer. This means that the reference count for each downloaded fragment never gets to zero and so its memory is never released.

I will attach a patch (against 1.2.0) that fixes this, plus two other very minor leaks that I've found. I have also checked git head and the bug is present there as well.
