Android CameraX VideoRecorder error > Encoder cannot created : null

I am building an Android app that records video using Camera X.
The probe in a Samsung A52 and it works correctly.
When running on a Galaxy Core A03 I get these errors:
E/Recorder: Unable to initialize video encoder.

I have it exactly as the Android documentation tells me.

I'm also having the same error after learning about CameraX at the following link https://developer.android.com/codelabs/camerax-getting-started
I think it's true what Morrison Chang said, there is something problem with Low End Android devices.
So I downgraded the quality of the Recorder contained inside the startCamera() function from HIGHEST to SD or HD and it's work.
val recorder = Recorder.Builder()
//.setQualitySelector(QualitySelector.from(Quality.HIGHEST))
.setQualitySelector(QualitySelector.from(Quality.SD))//change to Quality.SD or Quality.HD
.build()
videoCapture = VideoCapture.withOutput(recorder)

This issue has been opened in this google forum and the device was moto 360 as well. Here's the engineer's response:
There are many reasons why your Android Wear watch might show the
message “Android Wear has stopped”.
Make sure you are on the latest Android Wear app update.
Make sure you are on the latest Android Wear watch update
Try restarting your watch
If none of this works, then try unpairing and pairing again.
If none of this is not working, you might try other solutions users in
this thread used succesfully.
Go to Settings > Apps > Android Wear - Clear Cache and Clear Data. See if this helps.
Update Google app on your Android phone or iPhone
Check 3rd party apps and watch faces recently installed. Try uninstalling from phone and then reboot both watch and phone.
From Settings, Device, Apps, use the Uninstall updates button to back out the latest changes to Google Play Services, Then Clear cache
and Clear data. There could be a problem with the latest update of
Google play Services.
If you have problem with some specific manufacturer or you suspect it might be a Hardware issue, please contact them
Check steps on how to fix an app that is not working.

xamarin android camera throws stop face detection failed exception

I am starting a basic camera app using Android Intent.ActionImageCapture, StartActivityForResult() starts the camera app, but then it crashes even before capturing an image.
The Exception in logcat is java.lang.runtime Stop face detection failed.
I am not using face detection and have no need for it. And unable to handle this error.
So far this issue has occurred in 6.0.1, but works fine with versions lower and higher than 6.
This is the code:
Intent intent = new Intent(MediaStore.ActionImageCapture);
Java.IO.File _file = new Java.IO.File(m_cameraPhotosFolder, String.Format("mosaicfile_{0}.jpg", Guid.NewGuid()));
// Tell Camera where to save image
m_currentPhotoFileName = _file.AbsolutePath;
intent.PutExtra(MediaStore.ExtraOutput, Android.Net.Uri.FromFile(_file));
StartActivityForResult(intent, 0);

Any problems taking a portrait photo when device is in landscape?

I am making a rather specialist camera app for a device which is physically always going to be held in a landscape orientation. Part of the spec is that it must be able to preview and take photos in a portrait orientation - see image below.
I am having some trouble with a runtime exception "setParameters failed" (in response to a call to camera.setParameters()) and I just wanted to check here whether there was some fundamental problem that you think I might be up against. For example perhaps the light sensors on the back of the camera are a arranged in a rectangle and physically this can not be achieved - or perhaps some other unavoidable issue. (By the way I have been informed that the light sensors should be arranged in a square, so this problem will not occur - but my sources may be mistaken). Maybe this is hardware dependant?

I made a small camera test app a while ago. It was no problem, to show the camera preview in portrait mode, whilst the device was in landscape orientation. It was tricky to rotate the camera image by the right angle (because this rotation angle is device/camera dependant). A problem however was, that the perspective didn't match then: object seemed to be fatter or streched. But to find out the recalculating algorithm shouldn't take to much time on Stackoverflow.
So regarding
I just wanted to check here whether there was some fundamental problem
that you think I might be up against.
[...]and physically this can not be achieved - or perhaps some other unavoidable issue.
the answer is: it's a doable task. Your exception probably has a totally different reason.
