Gstreamer Opencv 后端实际上不支持此编解码器
Gstreamer Opencv backend doesn't support this codec acutally
这是我在启动自己的项目时遇到的问题，
OpenCV Error: Unsupported format or combination of formats (Gstreamer
Opencv backend doesn't support this codec acutally.) in

exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

我是 OpenCV 的新手，有人知道如何解决这个问题吗？您的线索也将不胜感激。
您似乎向 VideoWriter class 传递了不受支持的 fourcc 参数。
OpenCV 2.4.9 中 CvVideoWriter_GStreamer 的 fourcc 支持值列表可在以下位置找到：https://github.com/opencv/opencv/blob/2.4.9/modules/highgui/src/cap_gstreamer.cpp#L462.
出于好奇，你为什么使用自编译版本的 OpenCV？
