H265 UDP streaming problem

[Michiel Konstapel]

And/or on a h265parse element behind the encoder. In fact, you'll 
probably need both Nicolas' and Nick's suggestions: the receiver needs 
both a key frame and the information the config-interval inserts into 
the stream (SPS and PPS 
<https://www.quora.com/What-are-SPS-and-PPS-in-video-codecs>) to start 
decoding.

I don't know why it would work with h264; I'd expect the same issue.

Kind regards,
Michiel
