/***********************************************************
* In the top section are the functions that are used
* when processing the camera feed. Since these functions
* are internal to the RTSP module, and many require FFmpeg
* structures in their declarations, they are within the
* HAVE_FFMPEG block that eliminates them entirely when
* FFmpeg is not present.
*
* The functions:
* netcam_rtsp_setup
* netcam_rtsp_next
* netcam_rtsp_cleanup
* are called from video_common.c therefore must be defined even
* if FFmpeg is not present. They must also not have FFmpeg
* structures in the declarations. Simple error
* messages are raised if called when no FFmpeg is found.
*
* Additional note: Although this module is called netcam_rtsp,
* it actually handles more camera types than just rtsp.
* Within its current construct, it could be set up to handle
* whatever types of capture devices that ffmpeg can use.
* As of this writing it includes rtsp, http, files and v4l2.
