Recording Video

⚠️ WARNING

This documentation applies to versions below 1.0.0 and is DEPRECATED. If you're using version 1.0.0 or later, please refer to the updated documentation.

there's a little bit of difference between recording video and taking pictures with Camposer, but the methods to save are very similar with CameraState:

• ContentValues + MediaStore
• File
• ImageCapture.OutputFileOptions

All of these options use the method CameraState.startRecording or CameraState.toggleRecording, which has the last parameter: the callback with video capture result, and if successful, it contains the saved URI.

addition: if you're using CameraState.startRecording, to stop video use CameraState.stopRecording. With CameraState.toggleRecording just call twice.

Here is an example using the file:

val cameraState = rememberCameraState()
val isRecording = rememberUpdateState(cameraState.isRecording) // check if it's recording

val context = LocalContext.current
CameraPreview(
  cameraState = cameraState,
) {
  Box(
    onClick = { 
      cameraState.toggleRecording(file) { result -> 
        if (result is VideoCaptureResult.Success) { // result.savedUri might be useful to you
          Toast.makeText(context, "Success!", Toast.LENGTH_LONG).show()
        }
      } 
    }
  ) {
    Text(text = "Record: $isRecording")
  }
}

There's also support to suspend functions! Using suspend functions TakePicture it's return savedUri or throw throwable, so be careful when used it.
