No there aren't - because the “LIVE555 Streaming Media” software doesn’t do any
video decoding (or encoding), and what you’re asking for is a H.264 decoder.
Specifically, you want to decode the SPS NAL unit - the one that begins with
0x67 - to figure out the video width and height.
You can do this - but you’ll need to look in H.264 decoding software (e.g.,
“ffmpeg”) for the answer. Or you can look for the official ISO/IEC document
that describes H.264:
ISO/IEC 14496-10
