Hmm...it seems the tee muxer is mostly for encoding once, then outputting to several (the same encoded content) it apperas? In this particular instance I'm trying to encode multiple streams simultaneously "in parallel" so that I can use more cores (assuming each encoding uses at most 2 cores, which seems to be the case here). https://gist.github.com/rdp/0a152670b742053a2a69e8d54e613b9a was my attempt at it. I suppose it just isn't possible today, and I may file a trac feature request for it sometime.
