通过使用getElementByTagName()方法,我们可以精准定位我们想要找到的标签。它返回的是带有指定标签名的对象集合,也就是报错中的“NodeList”。 由于我想要的得到的信息还在更深层的标签中,所以我理所当然的再次使用了getElementByTagName()方法,这时候错误就产生了!!! why???我做错了什么!!!错的地方就是getElementB...
gstreamer gst_element_link_many decodebin 无法连接 gstreamer api,GStreamerAPI学习记录(二)基础概念单元Element是构成管道的组件Padpad是一个单元的输入输出端口,通过pad,才能将两个单元链接到一起。对输入来说,pad就是一个插口,对输出来说pad就是一个塞子。pad

Elements can be linked through their pads. If the link is straightforward, use the gst_element_link convenience function to link two elements, or gst_element_link_many for more elements in a row. Use gst_element_link_filtered to link two elements constrained by a specified set of GstCaps....
