我已经为相机直播和录制同时编写了gstreamer代码.

我的管道看起来像这样:

                 /  [ queue1 | videosink ]           
v4l2src | tee         
                 \  [ queue2 | filesink ]        

目前,直播和文件录制都在一起工作.

现在我需要只用一个队列即queue1(实时流队列)启动管道.过了一段时间我需要添加记录队列并动态删除它.

我的工作代码如下:

    pipeline = gst_pipeline_new ("rv_camera");

    /*Create source element. We use mfw_v4lsrc from Freescale as source */

    source= gst_element_factory_make (GSTREAMER_SOURCE,"camera-source");
    g_object_set(G_OBJECT(source),"device",camDeviceName, (char *)0);

    /*Set default properties of mfw_v4lsrc */
    g_object_set(G_OBJECT(source),"capture-width", CAMERA_CAPTURE_WIDTH,
                                  "capture-height", CAMERA_CAPTURE_HEIGHT,
                                  "sensor-width", CAMERA_SENSOR_WIDTH,
                                  "sensor-height", CAMERA_SENSOR_HEIGHT,
                                  "preview", CAMERA_PREVIEW_DISPLAY,
                                  "preview-width",CAMERA_PREVIEW_WIDTH,
                                  "preview-height",CAMERA_PREVIEW_HEIGHT,
                                  "fps-n",CAMERA_FRAMERATE,
                                  "rotate",mirror_effect,
                                  (char *)0);


    /* Tee that copies the stream to multiple outputs */
        tee = gst_element_factory_make("tee", "tee");

        /* Queue creates …
