Class Camera1ApiManager

java.lang.Object

uizalivestream.uiza.encoder.input.video.Camera1ApiManager

All Implemented Interfaces:

android.hardware.Camera.FaceDetectionListener, android.hardware.Camera.PreviewCallback

public class Camera1ApiManager
extends java.lang.Object
implements android.hardware.Camera.PreviewCallback, android.hardware.Camera.FaceDetectionListener

Created by loitp on 20/01/17. This class need use same resolution, fps and imageFormat that VideoEncoder Tested with YV12 and NV21.

Advantage = you can control fps of the stream. Disadvantages = you cant use all resolutions, only resolution that your camera support.

If you want use all resolutions. You can use libYuv for resize images in OnPreviewFrame: https://chromium.googlesource.com/libyuv/libyuv/
