Adding an RTSPS video stream (RTSP over TLS)

lmilcent · June 2, 2023, 6:59am

Can you confirm whether RTSP over TLS is supported (RTSPS)?
I don’t think so, or at least my tests didn’t seem to work.

What bothers me about RTSP is that it’s the only stream transmitted in cleartext on my home network. Of course, the risks are low, but I like to be as close as possible to the state of the art, especially in computer security when I have the opportunity and the means

Normally yes:

github.com/FFmpeg/FFmpeg

libavformat/rtsp.c

                  rt->control_transport = RTSP_MODE_TUNNEL;
              }
              /* Only pass through valid flags from here */
              rt->lower_transport_mask &= (1 << RTSP_LOWER_TRANSPORT_NB) - 1;
          
          redirect:
              /* extract hostname and port */
              av_url_split(proto, sizeof(proto), auth, sizeof(auth),
                           host, sizeof(host), &port, path, sizeof(path), s->url);
          
              if (!strcmp(proto, "rtsps")) {
                  lower_rtsp_proto         = "tls";
                  default_port             = RTSPS_DEFAULT_PORT;
                  rt->lower_transport_mask = 1 << RTSP_LOWER_TRANSPORT_TCP;
              }
          
              if (*auth) {
                  av_strlcpy(rt->auth, auth, sizeof(rt->auth));
              }
              if (port < 0)
                  port = default_port;

What error message do you get when you « try » the stream? (possibly check the logs)

PS: I created a thread to quietly debug this in a dedicated topic

When I ran tests, it wasn’t working.

In the meantime, I realized that the default port was incorrect (322/TCP). After modifying the camera configuration (MediaMTX), it’s working.

I configured this in Gladys:

rtsps://192.168.1.84:322/cam
