gmfbridge memory leak on removing clips

[joreg]

helo..

i am dynamically loading clips to be played back seamlessly via a
gmfbridge. as soon as the new clip is loaded, the bridge is switched
to that new sourcegraph and the old clip is freed.

i notice, that with every switch to a new clip i loose about 300k of
memory even though i FreeAndNil (in delphi terms) the no longer needed
clip.

also i note when loading a clip and never switching to it before
removing it again, memory is not lost.

is there anything i could be doing wrong?
hope so,
joreg.

false alarm: turned out the problem was linked to the video decoder
used: picvideo 4. all other decoders i tested (including picvideo 3)
don't show that leak.
