[Libav-user] Multi threaded encode

I want to run a I-frame based codec multi threaded so that I can get it encoding faster on a multi core pc.
If I open n streams can I simply change the steam index when I av_write_interleaved_frame or will it buffer because it assumes it has the mix the other streams (that'll never get filled). I don't have the ram for that.
If I take responsibility for the interleaving will it work that way?
What if I simply change the encoder flag to include the threaded-frame attribute (it already has the threaded slice attribute)? Will that make av_encode2 non-blocking? If so I can encode n frames at a time and block on a av_flush right?
Thanks for pointers.
