CamcorderProfile cpVGA = CamcorderProfile.GetAll(cameraId, CamcorderQuality.Qvga);
this does not get resolved because the cameraId that I generated is a string and not Java.Lang.String...
Referring to this official documentation [getAll](https://developer.android.com/reference/android/media/CamcorderProfile#getAll(java.lang.String,%20int\)), we could find that the following tips:
String: the id for the camera. Numeric camera ids from the list received by invoking CameraManager#getCameraIdList can be used as long as they are CameraMetadata#REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE and not EXTERNAL. This value cannot be null.
Therefore, we could use string cameraId = manager.GetCameraIdList()[0]; to get the cameraId.
If you remove the part of the profile and use API29, just using mediaRecorder.SetVideoSize(1280, 720); for recording, would the error occur?
that is how I already get cameraId however GetAll rejects it.
mediaRecorder.SetVideoSize(1280, 720) does execute but without any difference.
what I am expecting that for a 10M video file the time duration will increase as resolution decreases???
Did you use HasProfile method for checking whether your camcorder supported the quality?
Returns true if a camcorder profile exists for the first back-facing camera at the given quality level.
Did you use android.hardware.camera in your project?
Referring to this documentation Camera, we could find that:
This class was deprecated in API level 21.
We recommend using the new API for new applications.android.hardware.camera2.
I am using the Camera2VideoFragment so its not the Camera API. In the openCamera method
cameraId = manager.GetCameraIdList()[0];
this gives a string that I use in GetAll which is rejected by the compiler. I am not sure how to convert string to Java string???? I am not sure that I am on the right path???
Did you use the sample repo https://github.com/xamarin/monodroid-samples/tree/main/android5.0/Camera2VideoSample?
If so, I've tested the sample and make it usable.
You could modify your mediarecoder part as the following code:
mediaRecorder.SetAudioSource (AudioSource.Mic);
mediaRecorder.SetVideoSource (VideoSource.Surface);
mediaRecorder.SetProfile(CamcorderProfile.Get(CamcorderQuality.Q720p));
mediaRecorder.SetOutputFile(GetVideoFile(Activity).AbsolutePath);
int rotation = (int)Activity.WindowManager.DefaultDisplay.Rotation;
int orientation = ORIENTATIONS.Get (rotation);
mediaRecorder.SetOrientationHint (orientation);
mediaRecorder.Prepare ();
ABSOLUTELY GENIUS!!!!! Brilliantly simple yet EXTREMELY OBJECTIVE!!!!!
I think this was superseding the quality used in earlier attempts
mediaRecorder.SetOutputFormat(OutputFormat.Mpeg4);
I will test this further. I am not sure how to mark your answer as the solution to the question. If you can please mark it as ANSWER.
Thank You
Sorry I don't know how to mark your Post as ANSWER...could you please tell me how to do it or if you can mark it as Answer Please do so!!!!
