Another one YI CAM

[Brokly]

Hello ! Thanks a lot for your work!
I tried to hack a camera very similar to #84 .
For the hack I used kit 9.0.41* - b091qp. As a result, the hack was installed successfully, but RTSP and High res snapshot do not work. Can you help me? There is a photo and a backup of the original firmware https://github.com/Brokly/YI-CAM/tree/main/Files . Thank you !

[roleoroleo]

I will check it asap.

[roleoroleo]

Your cam is a different b091qp.
Please send me 3-4 copies of the file /dev/shm/fshare_frame_buf.

[Brokly]

Thanks for the feedback. As it turned out, FTP does not work either :( . When reading the SD card directly, I did not find such a way ( /dev/shm/fshare_frame_buf) . Maybe I misunderstood something ?

[roleoroleo]

You should be able to use ftp to login to the cam.
Or you should try scp.
The file is not available inside the sd card.

[Brokly]

That's all that was in this catalog https://github.com/Brokly/YI-CAM/upload/main/dev/shm . I didn't notice before that I need a "root" login to access FTP. So there is access to FTP.

[roleoroleo]

Your frame buffer file is the same as other versions of b091qp.
So, the released version should work.

[Brokly]

Unfortunately it doesn't work. Even using the link from the web interface, I can't see the video stream (rtsp://192.168.1.246/ch0_1.h264).

[roleoroleo]

Please, post your config hiding personal data.
cat /tmp/sd/yi-hack/etc/system.conf

Did you configure authentication?
If you set it, you need to add to the rtsp address.

Otherwise we need to debug the process.

[Brokly]

I set the login and password in the web interface. Do you need any other actions to configure authentication ?

[roleoroleo]

I set the login and password in the web interface. Do you need any other actions to configure authentication ?

No.
These credentials are used by http, rtsp and onvif daemons.
So the rtsp client must use them.

[Brokly]

Are there any other actions that can help me?

[roleoroleo]

Try to select the "Alternative RTSP server" and check if it works.

[Brokly]

Yes, I tried to turn on the alternative RSTP. It was not possible to connect to the video stream. All my camera can do is a low-resolution snapshot, everything else doesn't work.

[roleoroleo]

We need to debug the process.
Please follow these steps:

• restore the default rtsp server
• login with ssh
• run the following commands:

. /tmp/sd/yi-hack/script/env.sh
killall wd_rtsp.sh
killall rRTSPServer
rRTSPServer -d 3 -m b091qp -r high -a no -p 554 2>&1

• run vlc and connect to the cam at rtsp://192.168.1.246/ch0_0.h264
• post the log

Then try again with low res:

• login with ssh
• run the following commands:

. /tmp/sd/yi-hack/script/env.sh
killall wd_rtsp.sh
killall rRTSPServer
rRTSPServer -d 3 -m b091qp -r low -a no -p 554 2>&1

• run vlc and connect to the cam at rtsp://192.168.1.246/ch0_1.h264
• post the log

[Brokly]

I apologize for the long silence. This is what happens already at the first stage of debugging:

Maybe need to specify the path to the rRTSPServer, but I didn't find it: (And I was also alerted by the warning: "mounting: failed to mount in /sys/kernel/debug: resource is busy." Maybe that's the problem?

[Brokly]

The Github interface strangely changes the formatting, but the content is the same.

[roleoroleo]

You miss a "." at the first line.

[Brokly]

Yes, I really missed the dot symbol. My apologies. VLC logs are here https://github.com/Brokly/YI-CAM/blob/main/Files/log.7z

[roleoroleo]

Sorry for the misunderstanding, I need the log of the rRTSPServer process (in the console).

[Brokly]

OK, here are these logs https://github.com/Brokly/YI-CAM/blob/main/Files/LogrRTSPServer.7z

[roleoroleo]

The log is ok, the grabber is working properly and the frames are extracted without errors.
But I can't see a network connection.
The log does not contain any connection attempt.
Are you sure that your connection is ok?

[Brokly]

Yes, the connection is normal. I connect via SSH and Telnet, I get a low-resolution snapshot. But I can't get the video : (VLC logs show that I can't connect. In addition, I used a smartphone, the result is the same.

[roleoroleo]

VLC log reports "live555 debug: connection error -10057"
I found some issues about authentication.
Please, try to remove user/password temporarily.

[Brokly]

Thanks for the advice ! I will be able to check only in a week.
