Describe your Idea

Originally raised by @jonra1993 in https://github.com/abhiTronix/vidgear/pull/384

Adding support for SRTP/RTSPS or Secure RTSP streaming protocol for APIs like WriteGear and StreamGear.

Use Cases

This issue aimed at adding support for SRTP/RTSPS or Secure RTSP streaming, is protocol that is an extension of the RTSP/RTP protocol to encrypt the video frames and audio data. SRTP uses the same ciphers as HTTPS, typically AES with 128 bit key length. As AES uses a symmetric key, both the video producer and video consumer need to know the key.
