All, I am new to Gstreamer but have been impressed at the ease with which I got it running on my embedded platform. I now have A/V decode running on my embedded decoders and using GStreamers input-selectors/queues and demux+filesrc etc to make this happen. However, the system I am developing on has < 64 mb RAM. Once the system starts up and runs I am left with 20MB odd for applications. Once I start up Gstreamer it really seems to eat memory with it using nearly all the 18-20MB to run. Some of this is due to my A/V queue lengths. But a lot of it seems to be untraceable. My questions are: 1. Any hints on tracking where memory has gone. 2. Does Gstreamer have a memory manager where I could limit what it can use (much like Java allows) so that I could say heres 10MB no more 3. Is anyone else running on embedded systems finding similar issues? I suspect I am missing some options, my design choices might be floored or many other reasons so I really would appreciate any hints or tips for this. In the mean time calling free and checking calls to malloc (g_malloc) seems the only way forward Many thanks Daniel Laird
