How to use Burst mode in CameraX like Camera2 API

[朱纹凡]

I searched  the relevent api in CameraX but not getting the correct process.Please help me.Thanks

[Scott Nien]

CameraX does not plan to expose all Camera2 APIs. We would rather add high level API that supports certain useful scenarios.  So can you tell us more about your use case and details?

Thank you for your reply, I want to take 6 photos at a time, but at present I can't think of other methods besides getting the picture of each frame.

More details will be helpful . 
What do you want to do after getting the 6 photos ?   Are these 6 photos taken with the same request options Or you want each request has different option ?

Our app will take six photos quickly and choose the best photos for glamorous processing.

CaptureBurst can be used in Cmaera2, but I upgraded to AndroidX using CameraX. I don't know how to do it.

Unfortunately CameraX does not allow taking continuous shots for now. We do have a plan to support advanced features like this but no guaranteed schedule. 
Thanks for letting us know your use case.

[Christian Günther]

Sorry for necrobump this discussion, but is there any progress of providing capture bursts?

[Android CameraX Discussion Group]

Thank you so much for reaching out again! This feature is in our pipeline, unfortunately, we don't have a public schedule for this feature now.

[Philipp Puehringer]

I'm trying to build a FocusStacking app. For that i would need to take a series of images at different focal distances while displaying a preview. Is such task possible with CameraX and if so what would be the easiest way to impletment?

I've also heard about captureBurst from Camera2 Api this would fit my needs well, but my progress would need to be rewriten with Camera2 instead of CameraX.

Sorry for my bad english, Kind Regards from Austria,

Philipp

[tonyt...@google.com]

Does the latency between each capture matter for your application? If so, capture burst approach is recommended. Although it will still take some time for the focus to converge.

On the other hand, the CameraX approach may be submitting the captures repeatedly and using Camera2CameraControl API in between to apply different focal distance. Note that the specified focal distance will also affect the preview.

[Philipp Puehringer]

thanks for your reply, latenzy does not really matter, but the faster the better.

that second approach is the way i would like to take. when changing settings like focus do i have to rebind my usecases between each frame that gets captured? or when is the best time to change those settings with the Camera2CameraController?

[tonyt...@google.com]

No it doesn't have to be rebound. By using Camera2CameraControl, the capture request options are dynamically applied to all use cases that are bound to the camera. So you may change the focus settings after receiving the previous capture success callback, then wait for the future returned by setCaptureRequestOptions to complete, then capture the next image. Beware that by changing the focus related settings, it may interfere with the focus feature provided by CameraX and cause unexpected behavior when used together.

[Philipp Puehringer]

this helped me already a lot setting focus is implemented and i got the Callback to know if a image save working.

imageCapture!!.takePicture(

    outputOptions, cameraExecutor, object : ImageCapture.OnImageSavedCallback

      {override fun onImageSaved(output: ImageCapture.OutputFileResults)

         {val savedUri = output.savedUri ?: Uri.fromFile(photoFile)

          Log.d(TAG, "Photo capture succeeded: $savedUri")
          }

      })

var captureRequestOptions = CaptureRequestOptions.Builder()
.setCaptureRequestOption(CaptureRequest.CONTROL_AF_MODE, CameraMetadata.CONTROL_AF_MODE_OFF)
.setCaptureRequestOption(CaptureRequest.LENS_FOCUS_DISTANCE, distance).build()
Camera2CameraControl.from(camera!!.cameraControl).captureRequestOptions  =
captureRequestOptions

unfortunatly I dont know how to get that future object returned from setCaptureRequestOprions. Can you please give me some hints how to do this task. i would be grateful.

Kind regards

[tonyt...@google.com]

setCaptureRequestOptions returns a ListenableFuture, which can be used to monitor the execution result. Here is a guide and you may want to add a callback to start the next capture after the capture request options has been successfully applied.

[Philipp Puehringer]

i have created that callback as follows:

var listenableFuture = Camera2CameraControl.from(camera!!.cameraControl).setCaptureRequestOptions(captureRequestOptions)
Futures.addCallback(listenableFuture,object : FutureCallback<Void> {
override fun onSuccess(result: Void?) {
Log.d(TAG, "Focus set!")
}

override fun onFailure(t: Throwable?) {
Log.e(TAG, "Failed setting Focus ${t!!.message}")
}

},context!!.mainExecutor)

and it is giving me an that error message:

Failed setting Focus Camera2CameraControl was updated with new options.

Eventhough it is setting the focus. what am i doing wrong?

[Philipp Puehringer]

Never mind, got it working now. thank you so much for helping out.
by the way CameraX is by far the easiest API  to use. The implementet methodes work like a dream (e.g.setLinearZoom(float)). love it.
please keep on adding. my personal favorit would be a focus controll and a burst mode as you can already gues:)
