Захват видео с собственного программного источника

Разработка

В сборке Android SDK 1.1.0.26 добавлена возможность подключить собственную программную реализацию камеры для захвата изображения. Для этого необходимо:

1. Разработать Java класс, реализующий интерфейс CameraVideoCapturer

2. Импортировать в приложение модули
   

   import org.webrtc.CameraVideoCapturer;
   import com.flashphoner.fpwcsapi.camera.CameraCapturerFactory;
   import com.flashphoner.fpwcsapi.camera.CustomCameraCapturerOptions;
   import com.flashphoner.fpwcsapi.camera.CustomCameras;
   

3. Подготовить объект CustomCameraCapturerOptions
   

   private CustomCameraCapturerOptions createCustomCameraCapturerOptions() {
     return new CustomCameraCapturerOptions() {
   
         private String cameraName;
         private CameraVideoCapturer.CameraEventsHandler eventsHandler;
         private boolean captureToTexture;
   
         @Override
         public Class<?>[] getCameraConstructorArgsTypes() {
             return new Class<?>[]{String.class, CameraVideoCapturer.CameraEventsHandler.class, boolean.class};
         }
   
         @Override
         public Object[] getCameraConstructorArgs() {
             return new Object[]{cameraName, eventsHandler, captureToTexture};
         }
   
         @Override
         public void setCameraName(String cameraName) {
             this.cameraName = cameraName;
         }
   
         @Override
         public void setEventsHandler(CameraVideoCapturer.CameraEventsHandler eventsHandler) {
             this.eventsHandler = eventsHandler;
         }
   
         @Override
         public void setCaptureToTexture(boolean captureToTexture) {
             this.captureToTexture = captureToTexture;
         }
   
         // Use your custom capturer class name here
         @Override
         public String getCameraClassName() {
             return your.custom.CameraCapturer;
         }
   
         @Override
         public Class<?>[] getEnumeratorConstructorArgsTypes() {
             return new Class[0];
         }
   
         @Override
         public Object[] getEnumeratorConstructorArgs() {
             return new Object[0];
         }
   
         // Use your custom capturer enumerator name here
         @Override
         public String getEnumeratorClassName() {
             return your.custom.CameraEnumerator;
         }
     };
   }
   

4. В приложении перед публикацией потока выбрать собственную камеру
   

   CameraCapturerFactory.getInstance().setCustomCameraCapturerOptions(createCustomCameraCapturerOptions());
   CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.CUSTOM);
   

Пример использования

Используем собственную реализацию CameraVideoCapturer для доступа к вспышке:

1. Создание объекта CustomCameraCapturerOptions
   code

   private CustomCameraCapturerOptions createCustomCameraCapturerOptions() {
     return new CustomCameraCapturerOptions() {
   
         private String cameraName;
         private CameraVideoCapturer.CameraEventsHandler eventsHandler;
         private boolean captureToTexture;
   
         @Override
         public Class<?>[] getCameraConstructorArgsTypes() {
             return new Class<?>[]{String.class, CameraVideoCapturer.CameraEventsHandler.class, boolean.class};
         }
   
         @Override
         public Object[] getCameraConstructorArgs() {
             return new Object[]{cameraName, eventsHandler, captureToTexture};
         }
   
         @Override
         public void setCameraName(String cameraName) {
             this.cameraName = cameraName;
         }
   
         @Override
         public void setEventsHandler(CameraVideoCapturer.CameraEventsHandler eventsHandler) {
             this.eventsHandler = eventsHandler;
         }
   
         @Override
         public void setCaptureToTexture(boolean captureToTexture) {
             this.captureToTexture = captureToTexture;
         }
   
         // Using org.webrtc.FlashlightCameraCapturer to access flashlight hidden controls.
         @Override
         public String getCameraClassName() {
             return CustomCameras.FLASHLIGHT_CAMERA_CAPTURER;
         }
   
         @Override
         public Class<?>[] getEnumeratorConstructorArgsTypes() {
             return new Class[0];
         }
   
         @Override
         public Object[] getEnumeratorConstructorArgs() {
             return new Object[0];
         }
   
         // Using org.webrtc.FlashlightCameraEnumerator to access flashlight hidden controls.
         @Override
         public String getEnumeratorClassName() {
             return CustomCameras.FLASHLIGHT_CAMERA_ENUMERATOR;
         }
     };
   }
   

2. Выбор камеры
   code

   CameraCapturerFactory.getInstance().setCustomCameraCapturerOptions(createCustomCameraCapturerOptions());
   mCameraCapturer = (LabelledSpinner) findViewById(R.id.camera_capturer);
   mCameraCapturer.setOnItemChosenListener(new LabelledSpinner.OnItemChosenListener() {
      @Override
      public void onItemChosen(View labelledSpinner, AdapterView<?> adapterView, View itemView, int position, long id) {
          String captureType = getResources().getStringArray(R.array.camera_capturer)[position];
          switch (captureType) {
              case "flashlight":
                  CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.FLASHLIGHT_CAMERA);
                  break;
              case "camera1capturer":
                  CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.CAMERA1CAPTURE);
                  break;
              case "camera2capturer":
                  CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.CAMERA2CAPTURE);
                  break;
              case "custom":
                  CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.CUSTOM);
                  break;
          }
          mCameraSpinner.setItemsArray(Flashphoner.getMediaDevices().getVideoList());
      }
   
      @Override
      public void onNothingChosen(View labelledSpinner, AdapterView<?> adapterView) {
   
      }
   });
