要在Android应用程序中实现IP相机X和Camera2功能，需要遵循以下步骤：

1. 首先，在AndroidManifest.xml文件中添加摄像头和Internet权限。

2. 然后，在build.gradle文件中添加以下依赖项。

implementation ‘androidx.camera:camera-core:1.0.0’ implementation ‘androidx.camera:camera-camera2:1.0.0’ implementation ‘androidx.camera:camera-lifecycle:1.0.0’ implementation ‘androidx.camera:camera-view:1.0.0-alpha20’ implementation ‘com.github.pedroSG94.mjpegviewer:mjpeg-viewer:1.7.5’

3. 接下来，使用CameraX API连接到IP相机并启动视频流：

val cameraProviderFuture = ProcessCameraProvider.getInstance(context) cameraProviderFuture.addListener(Runnable { val cameraProvider: ProcessCameraProvider = cameraProviderFuture.get()

val preview = Preview.Builder().build()
val imageAnalysis = ImageAnalysis.Builder()
    .setBackpressureStrategy(ImageAnalysis.STRATEGY_KEEP_ONLY_LATEST)
    .build()

val cameraSelector = CameraSelector.Builder()
    .requireLensFacing(CameraSelector.LENS_FACING_BACK)
    .build()

val imageReader = ImageReader.newInstance(640, 480, ImageFormat.YUV_420_888, 2)

val camera = cameraProvider.bindToLifecycle(lifecycleOwner, cameraSelector, preview, imageAnalysis)
camera.cameraControl.enableTorch(true)

preview.setSurfaceProvider(viewFinder.createSurfaceProvider(camera.cameraInfo))

}, ContextCompat.getMainExecutor(context))

4. 最后，将MJPEG流连接到应用程序并开始播放：

val viewer = Mjpeg.newInstance() viewer.setDisplayMode(MjpegView.MODE_FIT_WIDTH) viewer.setInputStream(URL("http://192.168.0.1/mjpeg").openStream()) viewer.showFps(false) viewer.setResolution(640, 480)

viewer.setAdjustHeight(true) viewer.adjustHeightToWidthRatio(0.70f)

cameraContainer.addView(viewer) viewer.start()
