[vlc-devel] H264 without audio crashes the windows AX plugin

Hi Remi and all,
Thanks for the prompt response.
I don't think it's a long term memory leak. Perhaps I didn't describe the scenario properly.
The IE crashes without any warning after 30 sec when I am playing 16 assets. The CPU usage is about 70%. When I play 9-10 assets on the same application the CPU usage is no more than 50% and still it crashes after 1-2 minutes. There is no long term, it crashes almost immediately.
When I am playing on the same application 1-3 assets it can hold 48 hours without crashing....
So, it looks that the problem is on mutual resources exclusion and not memory leak because 30 sec is not a reasonable time for consuming 4GB of RAM.
I think the problem lays in the facts that the stream is half frame rate or that it's without audio because when I am playing full frame rate with audio I don't see any problems. But I am no master I just can say what I can see...
I'll appreciate any lead on this one.

This sounds like a long-term memory leak.
