Video recording and Frame processing simultaneously about cameraview-ex HOT 5 CLOSED

@bipinvaylu Technically it is possible but it might require some api level changes might even have to deprecate some current apis. Can you provide some more description about your use case like what kind of formats you use and what is the exact use case that you are trying to implement. Preview frames and video can be very different in terms of size and quality.

Thanks @pvasa for a quick response, Yeah, Actually I am trying to achieve my use case since last few days. But unable to find any sustainable solution so far. Please find the proper use case details here: https://stackoverflow.com/questions/54091648/camera-2-api-to-preview-record-and-extract-the-preview-frame-to-firebase-face-d

Btw, If you can provide me some help/insight for the same. I can work out that way and if able achieve, I will push it here as well for others.

@bipinvaylu the way to achieve this would be to provide both mediaRecorder surface and imageReader surface to videoRequestBuilder and camera?.createCaptureSession(..). So you will need to update startVideoRecording().
You can take a shot at it and let me know if you need any help, meanwhile I am implementing (updating) the CameraView.cameraMode api to achieve exactly this functionality. With this update you will be able to enable multiple camera modes at the same time. For eg., SINGLE_CAPTURE and CONTINUOUS_FRAME or VIDEO_CAPTURE and CONTINUOUS_FRAME or even all 3 (possibly).

@bipinvaylu Release v3.0.1-beta now supports this feature.

Video capturing and frame processing can be achieved simultaneously by using below methods

• In xml

app:cameraMode="continuous_frame|video_capture"

• Or in code

camera.cameraMode = Modes.CameraMode.CONTINUOUS_FRAME or Modes.CameraMode.VIDEO_CAPTURE
