本代码是使用GStreamer播放RTSP视频流,没有使用playbin,而是自己构建pipeline,经测试可以正常播放视频。
通过gst-launch验证的字符串Pipeline可以直接使用gst_parse_launch()接口将其转化为GstPipeline对象,节省了我们单独调用API去创建Element的时间。 当我们用字符串描述Pipeline时,每个Element之间需要通过叹号 “!" 分隔Element,这样gst-launch才能正确识别。 在使用gst-launch时,根据不同的应用场景,我们可以分为以下的类型。

The user must insure that all selected plugins and features (element, typefind, etc.) have been enabled during the build configuration. To register features, the syntax is the following: plugins are separated by ';' and features from a plugin starts after ':' and are ',' separated. ...
GStreamer 则采用了基于管道的插件架构,各个功能模块之间通过元素(Element)连接,灵活性更高。 适用场景: 如果需要快速进行批量转码、简单剪辑或者直接调用命令行工具,FFmpeg 是非常合适的选择; 对于需要构建复杂数据流、实时处理、或者集成到图形界面应用中的项目,GStreamer 更能发挥其优势。
