RTSP Issues

[sebastianfelipe]

Description Hi! Well, I have dedicated a lot of hours trying to streaming a RTSP local connection, but It couldn't be possible. I tried with licode-v7 (I think this is impossible, because some bugs that were fixed later on the code). Also tried with the latest version (I think this have a lot of bugs, it cannot be possible almost any) But, with version 8, I think I was closed. But I think there are some bugs or maybe a lack of documentation about it. I'm gonna describe the issue.

Steps to reproduce the issue:

1. Install licode v8
2. Using any Erizo client (the example, or something you have developed), try to configure it to stream RTSP. My config was:

        localStream = Erizo.Stream({
          audio: false,
          video: true,
          url: 'rtsp://<username>:<password>@<local IP>:<port>',
          attributes: {user: <user info>}
        });

3. You can do the previous step modifying the basic example too. It doesn't matter.
4. Run the code and read the logs

Describe the results you received: The logs in licode described very well what happened:

Describe the results you expected: I expected to stream a h264 video, from my local camera.

Additional information you deem important (e.g. issue happens only occasionally):

Licode commit/release where the issue is happening I tried it from version 7 and on

Additional environment details (Local, AWS, Docker, etc.): I used Docker environment and also installed in a VM. Same thing, I have dedicated a lot of hours in this.

I'd really appreciate your help. If I'm doing something wrong, I really appreciate a clarification, but I think there is issues related and I'm not sure why. It would be helpful if you can provide an example about streaming RTSP or a file, because it is not as easy as in the documentation.

Thanks, Sebastián.

I think it has bug when it use tcp. I think udp is ok.
