First, please properly trim old text (from the replied-to message) when
replying to emails.
Second, you don’t need to go to random third-party sites (like ‘github’) to get
“testRTSPClient”. It is already part of the “LIVE555 Streaming Media”
software; see

Perhaps (at least some of) your H.264 ‘key frames’ are too big for
“testRTSPClient”s receive buffer (by default, 100,000 bytes)? Are you seeing
error messages about byes being “truncated”?
In any case, you should reconfigure your encoder so that it breaks each ‘key
frame’ into multiple ’slice’ NAL units. This will make your video much more
resilient to network packet loss. Otherwise, the loss of even one RTP packet
will make the entire frame unusable by the receiving client. This is something
that I have commented on numerous times; see, for example:
