[FFmpeg-devel] rough PATCH: reducing the memory copies

[mmh]

This saves me about 50MIPS + reduce cache stress, by elliminating this
memory copy, which I guess happens later anyways again.

I know that I need to creat a new function in utils.c for this like
av_new_packet probably av_ref_packet which does the work in the if variant.

What are the problems with this and, other ideas that comes to mind?

Thanks
Marc
