 Using ffplay on Win32 I am trying to play an h264 rtsp stream from an Axis
 camera. ffplay freezes for approx. 2 seconds every 30 seconds. When
 looking at the stack av_get_random_seed seems the culprit.
 Every 30 seconds ffplay wants to send a keep-alive message.
 ff_rtsp_send_cmd_with_content_async calls ff_http_auth_create_response.
 ff_http_auth_create_response calls make_digest_auth. make_digest_auth
 calls av_get_random_seed. av_get_random_seed calls get_generic_seed. It
 looks like get_generic_seed takes approx. 1 second to complete.
