Yes, you missed the part where I said that:
each ‘frame’ that come from your input source must be a ***single***
H.264 NAL unit, and MUST NOT be prepended by a 0x00 0x00 0x00 0x01 ‘start code’.
So, you must deliver (without a prepended ‘start code’ in each case):
SPS, then
PPS, then
FRAME, etc.
***provided that*** FRAME is a single NAL unit. If, instead, FRAME consists of
multiple ‘slice’ NAL units (this is actually preferred for streaming, because
it’s much more tolerant of network packet loss), then you must deliver each
‘slice’ NAL unit individually (again, without a ‘start code’).
Also, when testing your server, I suggest first using “openRTSP”
<http://www.live555.com/openRTSP/> as a client, before using VLC.
