Issue in RTface application setup

[alisan]

Hi,

I am trying to setup RTface application, so far I am done with the server and now working on the client's components. Its github link is as follows:

junjuew/rtface

I am facing a problem setting up the video streaming source (camera-source) setup. I am unable to find the link between instructions for this part unfortunately. To be able to follow the following step:
Modify GABRIEL_IP in camera-source/config.py to be the IP of your RTFace server
I am simply not able to find the camera-source directory. Help in this regard would be highly appreciated. Thank you.
Special request to @junjuew and @teiszler. Thank you.

Hi @alisan,

Did you clone the junjuew/rtface repository? It should be at the top level. The line you want to change is in config.py here:

junjuew/rtface/blob/47daaf15a32391c03b5c37d2d5c28fda9a3ba048/camera-source/config.py#L4

Perhaps you are on a different branch than master in your local repo? You can check with git status. I see some of the other branches have different directory structures.

Regards,
Tom

Hi, I did not clone the junjuew/rtface repository but downloaded the pre-build container image using the following command
docker pull jamesjue/rtface
Now I shal go in the image storage directory and change it? I think I won't have access to the code that way to make the mentioned change. Is it so?

[teiszler]

So I believe there are two separate applications here. You can continue to run the RTFace backend by launching the pre-built docker image. You then want to setup the client somewhere else which will be the camera source. On that machine you can clone the repository, change the config, and then start ./ui.py so that it sends the video stream to the backend which you already have running elsewhere. Conceivably you could have them both on the same machine, running the backend in a container, and using the source repository on the host as the client. Does that make sense?

[alisan]

Yes, it does. Thanks a lot, I will work on this and get back with the feedback soon enough!

Hi Tom,
As per your (@teiszler) previous reply I proceeded in the same manner and was successfully able to set up the client. Unfortunately, I am still running into a few problems I am unable to figure out as of yet.

1. I am unable to access the link in the following instruction (after replacing the hostname of course):
   To view video streams after privacy preservation, go to https://hostname:10004
   I read the paper for this project and realized that this link is probably for IoTA Android App. I am still looking for it online though. Can you suggest why is this not accessible?

2. I am a bit confused about these instructions:
   Don't use camera-source's UI to add user, control user's policy, nor delete user.
   Instead, to add user, you should use trainer web server.
   However, in the demo video of RTFace shows the use of camera-source UI for training and the rest. And I am able to use and operate the camera-source in the same way just fine.
   Kindly clear this confusion as well please.

3. I tried using the web server for training, I was able to sign in using an email ID but the training doesn't start and no camera preview is shown either. I am still looking into this but just confirm that once this works and a face is trained, the person information will reflect in the camera-source UI or not?

Huge thanks in advance. Looking forward to your response, thank you!

Best,
Aliza

1. What's the error? ui.py needs to be started for the video stream to show.
2. As long as you are doing all the operations in either of Desktop app UI or the web apis/UI, it should be fine. A mix of adding/deleting people from both Desktop UI and the web apis may not work correctly.
3. What's the error in the dev console? The video source desktop app and the training webpage should be
   accessed by two different machines (e.g. desktop app on a laptop, training
   webpage through a smartphone), as a single camera typically cannot be accessed by
   two programs simultaneously. Self-signed certificate also needs to be accepted in order to access camera from the browser.

Thank you for your response @junjuew

1. I have started ui.py and desktop UI is working fine with that. The webpage against https://hostname:10004 simply shows the error that the site can't be reached because hostname's server IP address could not be found.
   Am I doing something wrong?
   And this can be accessed from the same PC or should I from another?

2. So you are suggesting its fine to use ONE of them?

3. I'll work on this and provide feedback asap.

Thanks,
Aliza

Regarding #1, it sounds like you are getting a DNS error. If ui.py is running on the same host as the webserver, then you could just use https://localhost:10004. If it is not the same host, you could try to avoid DNS and just use the IP address in the URL (https://x.x.x.x:10004)

Regarding #2, I believe @junjue is suggesting that you should use one or the other; not both.

Hi,
As mentioned by @junjuew I accessed the training webpage from my phone as well but there is still no camera preview and the training just doesn't start. What can be the possible reason for this? Also I have enabled chrome to accept self-signed certificates. And I have tried clicking the link to accept the certificate as well. (Screenshots attached)

Regarding #1 @teiszler I tried accessing again and it says the site cannot provide a secure connection and an invalid response is being sent (ERR_SSL_PROTOCOL_ERROR)

Apologies for too many questions and issues but I am relatively new at this and want to be entirely clear about the project. Thank you in advance.

[junjuew]

It would be great if you can provide more debugging info. What's the output from the dev console? What if you click on the "!" button in front of the url? (If I recall it correctly, there should be a popup asking for camera permission if you click on it).
