> What is the best way to actually encrypt my h264 stream with live555? Using SRTP. However, we do not support SRTP, because its use has not been defined (standardized) for RTSP 1.0. (It has been defined for RTSP 2.0, but almost nobody - including us - implements that.) Sorry. Ross Finlayson Live Networks, Inc. http://www.live555.com/
