I couldn’t find a single filter which calls avformat_new_stream(), and the docs 
for avformat_new_stream() indicate that it can only be called by input format 
handlers during read_header(), or it can also be called during read_packet() if 
AVFMTCTX_NOHEADER is set by the demux.

Don’t confuse what I’m asking about with the ability to have a filter which has 
one input and multiple outputs.  These are targeted at raw audio and video 
frames, as opposed to streams.

I would be quite happen to be proven wrong, of course.  Just point me to an 
example and I’m happy to copy/reuse whatever approach others have taken.
