G_SLICE=always-malloc valgrind --tool=massif --detailed-freq=20 gst-launch-1.0
playbin uri=file:///net/media/Videos/HD/The_Avengers.mkv flags=1
when playing a certain mkv file with 1.0 playbin, memory consumption will
steadily increase
i've filed this under gst-plugins-good because matroskademux maybe the source
of the problems.
ran it through valgrind with the massif tool and attached the report
