There's definitely a memory leak during video playback. I installed the recommended FFmpeg build (fmpeg-git-a254452-win32-shared.7z) and dropped a ~73MB mp4 file into an empty project then left it looping while I did something else. When I came back I was greeted by the low memory warning. I reproduced it and kept Process Explorer open during playback...

The graph shows an initial bump up to ~120MB usage when I imported the file then steady memory munch during playback, up to ~190MB when I stopped it after a minute or so.

Here's the source properties dialog text. I'm a video n00b so it makes little sense to me...

My output device was set to 44.1 so it was resampling using "Good 64pt Sinc" mode. I'm on Win7, 32 bit, 4.23pre7.
