Re: using extended params for MPEG4 encoding

Hi, I've been faced to a similar issue. Check that the parameters structure exist as long the Engine run (not allocated on the stack). The TI routine will simply keep the pointer and use it. It will not copy it. Hope this help. Sorry if I 've missed the target, but i'm very very loaded this tim
