use avio_open2 (not avio_open).  Avio_open2 takes AVDictionary of options
as a parameter.  Does anyone know how to find any documentation of the
options that an available for the RTMP protocol?

Have you confirmed that the H.264 stream produced by the hardware encoder
can actually be decoded by Youtube?  Some of these hardware encoders use
non-standard/less-common options that might cause problems with a streaming
service.  Since you're using "-vcodec copy" you're essentially just passing
through the NAL stream from the hardware encoder unmodified.

I would suggest trying it with an H.264 stream that isn't the output of the
hardware encoder, just to see if this is really a problem with the RTMP as
opposed to the H.264 stream contained within it.
