Not able to change video recording parameters on iOS

[Sendery]

Videos Settings always the same, dont change

I'm not able to change the video settings for iOS devices using the python function:

driver.start_recording_screen(videoFps="15",quality="high")

the values are examples

The appium server (1.12.1) is processing correctly the arguments and passing them to the wda but the wda is not updating its values.

I had try to connect via a REST client to the wda session in order to POST myself the new settings but the wda always returns a 200 with the same body and without any update.

POST /session/:session_id/appium/settings

Sent case 1

{
"mjpegServerScreenshotQuality":75,
"mjpegServerFramerate":25
}

Sent case 2

{
  "value":{
     "mjpegServerScreenshotQuality":75,
     "mjpegServerFramerate":25
  }
}

Received always

{
  "value": 
  {
    "screenshotQuality":1,
    "elementResponseAttributes":"type,label",
    "shouldUseCompactResponses":true,
    "mjpegServerFramerate":10,"
     mjpegServerScreenshotQuality":25
  },
  "sessionId":"68EF9DF3-FAE8-424C-859D-XXXXXXX6F",
  "status":0
}

Could you remove WDA once and run Appium 1.12.1 again?
From 1.12.0, mjpegScalingFactor has been introduced. It should be in the returned value if your WDA is over 1.12.0.

I uninstall de appium package and reinstall it, then I recompile the WDA, uninstall the WDA in the device and relaunch the appium. The driver.start_recording_screen() function resend the selected options but the behaviour is the same.

GET http://localhost:8000/status

{
  "value": {
    "state": "success",
    "os": {
      "name": "iOS",
      "version": "12.1.2",
      "sdkVersion": "12.0"
    },
    "ios": {
      "simulatorVersion": "12.1.2",
      "ip": "192.168.1.131"
    },
    "build": {
      "upgradedAt": "1554890714200",
      "time": "Apr 10 2019 12:12:31",
      "productBundleIdentifier": "com.facebook.WebDriverAgentRunner"
    }
  },
  "sessionId": "191B6834-7E7B-47DF-A959-5BCA0A35FAA7",
  "status": 0
}

POST http://localhost:8000/session/00957759-A8C0-4A49-9042-B50CD47F858D/appium/settings

{
  "mjpegServerFramerate": 23,
  "mjpegServerScreenshotQuality": 75
}

RESPONSE

{
  "value": {
    "screenshotQuality": 1,
    "mjpegScalingFactor": 100,
    "elementResponseAttributes": "type,label",
    "shouldUseCompactResponses": true,
    "mjpegServerFramerate": 10,
    "mjpegServerScreenshotQuality": 25
  },
  "sessionId": "00957759-A8C0-4A49-9042-B50CD47F858D",
  "status": 0
}

Now the "mjpegScalingFactor" appear but the options do not change on new settings POST.
Could you point me to a verified WDA repository to test it on my setup?

I see the problem

[mykola-mokhnach]

This should be fixed in appium@beta
