Описание

В сборке Andropid 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) {

            }
        });
