勿回，给搜索的人用的，大陆局域网内搜不到：
也许有人会要找怎么写格式转换的 “format”吧，如下：
g_object_set( G_OBJECT( geFltGray ),"caps",
         gst_caps_new_simple("video/x-raw-gray",
                                    "width",G_TYPE_INT,1000,
                              "height",G_TYPE_INT,720,
                              "bpp",G_TYPE_INT,8,
                              "depth",G_TYPE_INT,8,
                              "framerate",GST_TYPE_FRACTION,1,1,//帧率，根据自己情况修改
                              NULL
                              ),NULL);

g_object_set( G_OBJECT( geFltI420 ),"caps",
         gst_caps_new_simple("video/x-raw-yuv",
                  "format",GST_TYPE_FOURCC,GST_MAKE_FOURCC( 'I','4','2','0'  ),
                                    "width",G_TYPE_INT,1000,
                              "height",G_TYPE_INT,720,
                              "framerate",GST_TYPE_FRACTION,1,1,
            NULL
                              ),NULL);
