[Libav-user] [FFmpeg-user] RTMP issue

I think the stream is ok -- I have used the same program to write to protocol file: and then uploaded that to youtube with no issue.
Is that a good enough test the the stream format?

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.
