Question

There seems to be TVideoCaptureDevice in FireMonkey (Delphi XE6), but on official documentation, capturing process ends up on lines:

if(VideoCam

Here is how it is done on Android using native API:

var
    texture : JSurfaceTexture;
    surface: JSurface;
    recorder: JMediaRecorder;
begin
  texture := TJSurfaceTexture.JavaClass.init(1);
  surface := TJSurface.JavaClass.init(texture); 
  recorder := TJMediaRecorder.Create();

  recorder.setPreviewDisplay(surface);
  recorder.setAudioSource(AUDIO_MIC);
  recorder.setVideoSource(VIDEO_CAMERA);
  recorder.setOutputFormat(FORMAT_THREE_GPP);
  recorder.setAudioEncoder(AFORMAT_AMR_NB);
  recorder.setVideoEncoder(VFORMAT_MPEG_4_SP);
  recorder.setMaxDuration(1800000); // 30 minutes

  recorder.setVideoSize(320, 240);
  recorder.setVideoFrameRate(15);
  recorder.setOutputFile(StringToJString(TPath.GetSharedCameraPath + OUTPUT_FILE));

  recorder.prepare();
  recorder.start();
end;

File will be recorded, just don't forget to send recorder.stop() when you wish to stop recording.
