Switch resolution via API

[das-dos_208145718501556]

Hi!
I have a RLC-823A 16x and would like to change the resolution of the cam via API call (curl comand within linux script)
The API I am already using for making snapshots, but I do not know the API command for a resolution change.
Is this possible?

[Reolink Lorenz]

@das-dos_208145718501556 Hello there, you can switch resolution via API command listed below. Note that with camera resolution changed, the camera will restart and work again after restart.

[{
    "cmd": "SetEnc",
    "action": 0,
    "param": {
        "Enc": {
            "audio": 0,
            "channel": 0,
            "mainStream": {
                "size": "2560*1920"
            },
            "subStream": {
                "size": "640*480"
            }
        }
    }
}]

@das-dos_208145718501556 According the API v8 the following parameters are mandatory in command SetEnc.




And so the curl command should be as follows.

curl -s -k -X POST -H "Content-Type : application/json" -d "[{\"cmd": \"SetEnc\",\"action\": 0,\"param\": {\"Enc\": {\"channel\": 0,\"audio\": 1,\"mainStream\": {\"size\": \"2560*1920\",\"frameRate\": 20,\"bitRate\": 4096,\"profile\": \"High\"},\"subStream\": {\"size\": \"640*480\",\"frameRate\": 10,\"bitRate\": 256,\"profile\": \"High\"}}}" "https://#IP#/cgi-bin/api.cgi?cmd=SetEnc&user=#username#&password=#passwd#"

Please replace the IP with the cam IP and the username and passwd with your credentials.

And if it doesn't reboot you can reboot it using

curl -s -k -X POST -H "Content-Type : application/json" -d "[{\"cmd\":\"Reboot\",\"action\":0,\"param\":{}}]" "https://#IP#/cgi-bin/api.cgi?cmd=Reboot&user=#username#&password=#passwd#"

@joseph_1979 HI! Thanks for this response. The curl code for reboot is working fine. But the modification of the resolution unfortunately is not working. Maybe there is a syntax error within the code?

[joseph_1979]

@das-dos_208145718501556 ha haha I did that purposely for you to fix and I replied when I was having a bottle of fine wine with my friends...........Joking. I missed an escape character \. Try now. Replace the size, frame rate and bitrate with the appropriate values given in the stream menu. just follow the command in the API v8 doc provided by Reolink.

curl -s -k -X POST -H "Content-Type : application/json" -d "[{\"cmd\": \"SetEnc\",\"action\": 0,\"param\": {\"Enc\": {\"channel\": 0,\"audio\": 1,\"mainStream\": {\"size\": \"2560*1920\",\"frameRate\": 20,\"bitRate\": 4096,\"profile\": \"High\"},\"subStream\": {\"size\": \"640*480\",\"frameRate\": 10,\"bitRate\": 256,\"profile\": \"High\"}}}" "https://#IP#/cgi-bin/api.cgi?cmd=SetEnc&user=#username#&password=#passwd#"

[das-dos_208145718501556]

@joseph_1979 Hi Joseph, without a fine wine I am not able to make a clear thought at all

When trying your corrected code it seems to occur a problem with the authentification ("...Please login first...:"):



But I am 100% sure I am using my correct login data as the reboot code is working fine.

Any ideas?

P.S.: Many thanks Joseph for your kind assistance! That´s highly appreciated!

[das-dos_208145718501556]

@das-dos_208145718501556 by the way I am running this on a linux maschine if of importance

[joseph_1979]

@das-dos_208145718501556 They should improve the API by adding appropriate error codes and update the API doc if there are changes. The error indicates that we have a missing parameter. So we need to get the printout first. Maybe we need to add gop.

Send this to get what need to be included. You should get the initial (default) and the one set (Value)

curl -s -k -X POST -H "Content-Type : application/json" -d "[{ \"cmd\":\"GetEnc\", \"action\":1, \"param\":{ \"channel\":0}}]" "https://#IP#/cgi-bin/api.cgi?cmd=GetEnc&user=#username#&password=#passwd#

Don't worry about the private IP 172.16. 0.0 to 172.31. 255.255 (class B)....nobody will be able to access this IP from the Internet side.

[joseph_1979]

@das-dos_208145718501556 It's more simpler and robust. I do have a number of Linux machines G10 in VM/OpenStack.........but no MAC/IOS :).

@das-dos_208145718501556 Only the Initial was enough to know what is missing. So we need to add the I-Frame interval parameter gop.

Check again :).

curl -s -k -X POST -H "Content-Type : application/json" -d "[{\"cmd": \"SetEnc\",\"action\": 0,\"param\": {\"Enc\": {\"channel\": 0,\"audio\": 1,\"mainStream\": {\"size\": \"3840*2160\",\"frameRate\": 25,\"bitRate\": 8192,\"gop\": 2,\"profile\": \"High\"},\"subStream\": {\"size\": \"640*360\",\"frameRate\": 15,\"bitRate\": 512,\"gop\": 4,\"profile\": \"High\"}}}" "https://192.168.X.X/cgi-bin/api.cgi?cmd=SetEnc&user=#username#&password=#passwd#"

BTW what's the model?

[das-dos_208145718501556]

@joseph_1979 Thanks Joseph.

Copy/Paste your code (and changing IP, user and pw of course) does not work. Prompt is not coming back.
I slightly changed using ChatGPT into the following as ChatGPT said there is a wrong use of " and }:

curl -s -k -X POST -H "Content-Type : application/json" -d "[{\"cmd": \"SetEnc\",\"action\": 0,\"param\": {\"Enc\": {\"channel\": 0,\"audio\": 1,\"mainStream\": {\"size\": \"3840*2160\",\"frameRate\": 25,\"bitRate\": 8192,\"gop\": 2,\"profile\": \"High\"},\"subStream\": {\"size\": \"640*360\",\"frameRate\": 15,\"bitRate\": 512,\"gop\": 4,\"profile\": \"High\"}}}" "https://#ip#/cgi-bin/api.cgi?cmd=SetEnc&user=#user#&password=#pw#"

But using this code I receive the "login first" prob again:

[
  {
   "cmd" : "SetEnc",
   "code" : 1,
   "error" : {
     "detail" : "please login first",
     "rspCode" : -6
   }
  }
]

I have a RLC-823A 16X.

[joseph_1979]

@das-dos_208145718501556 Oops sorry to hear that it didn't work. Let me check it on my camera.

[joseph_1979]

@joseph_1979 Typing error.

Here it comes.

curl -s -k -X POST -H "Content-Type : application/json" -d "[{\"cmd\":\"SetEnc\",\"action\":0,\"param\":{\"Enc\":{\"channel\":0,\"audio\":1,\"mainStream\":{\"size\":\"3840*2160\",\"frameRate\":25,\"bitRate\":8192,\"gop\":2,\"profile\":\"High\"},\"subStream\":{\"size\":\"640*360\",\"frameRate\":10,\"bitRate\":512,\"gop\":4,\"profile\":\"High\"}}}}]" "https://192.168.X.X/cgi-bin/api.cgi?cmd=SetEnc&user=#username#&password=#passwd#"

If it works then I am better than chatgbt :). Don't forget to reboot after.

[das-dos_208145718501556]

@joseph_1979 wwwoow! That´s it, it´s working perfect! By the way: The reboot is initiated automatically by the webcam.
Many many thanks for your support Joseph! And as you say: ChatGPT is not on your level

@das-dos_208145718501556 You're welcome. Enjoy programming....it is unbelievable fun in particular C++.
