simaai::neat::H264EncodeSima::H264EncodeSima (int w, int h, int fps, int bitrate_kbps=4000, std::string profile="baseline", std::string level="4.0")

Construct with stream parameters and encoder profile.

Parameters

w	Frame width in pixels.
h	Frame height in pixels.
fps	Target encode framerate.
bitrate_kbps	Target output bitrate in kbps (default 4000).
profile	H.264 profile string ("baseline", "main", "high").
level	H.264 level string (e.g. "4.0").
