C++ 使用OpenCV创建视频-Gstreamer编解码器不工作

我正在尝试使用OpenCV将视频写入磁盘。该代码使用video writer对象以.mpg格式以30帧/秒的速度保存文件。我使用CV_FOURCC宏指定了编解码器，如下所示：

VideoWriter put("test.mpg", CV_FOURCC('M','P','E','G'), 30, S);

当我执行代码时，我得到一个错误：

userk@dopamine:~/Development/opencv-2.4.8/sketch/RegVideo$ ./vi
HIGHGUI ERROR: V4L/V4L2: VIDIOC_S_CROP
OpenCV Error: Unsupported format or combination of formats (Gstreamer Opencv backend doesn't support this codec acutally.) in CvVideoWriter_GStreamer::open, file /home/userk/Development/opencv-2.4.8/modules/highgui/src/cap_gstreamer.cpp, line 505

Aborted (core dumped)

我尝试过不同的编解码器，如MPEG-1、motion jpeg、MPEG-4.2、MPEG-4.3、MPEG-4、H263、H263I和FLV1，但都不起作用。问题似乎是V4L

我尝试使用以下命令安装它，但在生成后出现错误：

wget http://www.linuxtv.org/downloads/v4l-utils/v4l-utils-0.9.3.tar.bz2
tar xvf v4l-utils-0.9.3.tar.bz2
cd v4l-utils-0.9.3
make
sudo make install

这是错误消息：

v4l有什么问题？你有什么建议吗
