Memory profiling and hunting memory leaks

[Loc Nguyen]

Hey, I sent an email a few days ago but was never sent to the mailing
list.  I'm trying to hunt down some memory leaks in gstreamer on
Windows.  Can anyone advise on how core gstreamer devs are doing this?  
Any internal APIs that maybe useful for me to try?

  There isn't anything in the GStreamer API that would help you to
*track* this down.
  On Linux and MacOSX most of us use valgrind, here's how we use it :
  http://live.gnome.org/Valgrind

  If you have access to a Linux or MacOSX machine, you can try
reproducing your use-cases there and use valgrind to find the leaks.
  If you don't have access to such machines, or you have
windows-specific plugins, then you'll have to look for a memory profiler
for windows (don't know of any).

  Here's another example of using valgrind more oriented towards
gstreamer-based applications:
