Hello,
I found memory leak with flvdemux plugin (71 bytes in 1 blocks are definitely
lost). Memory leak testing performed using Valgrind(Valgrind-3.7.0).  
Command used for testing:
G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind -v --tool=memcheck
--leak-check=full --track-origins=yes --suppressions=gst.supp
--log-file=valgrind_gst.log gst-launch-1.0 filesrc location=Input.flv !
flvdemux name=demux demux.audio ! queue ! 'audio/mpeg,mpegversion=4' ! flvmux
name=mux ! filesink location="dummy.flv" demux.video ! queue ! mux.video
