gst-inspect-1.0 命令

常用示例

说明

gst-inspect-1.0 queries information about GStreamer plugins and elements. It displays element details including pad information, capabilities, properties with types and defaults, and available signals. Without arguments, it lists all available plugins and their elements with summaries. With an element or plugin name, it shows detailed information about that component, including the element's factory details, pads, properties, and signals. This is an essential tool for GStreamer pipeline development, allowing developers to discover available elements, understand their capabilities, and check property types before constructing pipelines with gst-launch-1.0.
