Python：在 gstreamer 管道中获取媒体的分辨率
[英]Python: Getting the resolution of the media in a gstreamer pipeline
问题描述
As the title suggests, I need a way to get the resolution of the media running in the Gstreamer pipeline.
正如标题所示，我需要一种方法来获得在 Gstreamer 管道中运行的媒体的分辨率。 I know it has something to do with the caps in the pipeline.我知道这与管道中的上限有关。 But how do I access it?但是我如何访问它？ Also, let's say I somehow got it and it is of the type Gst.caps, how do I get the actual width and height from this?另外，假设我以某种方式得到它并且它是 Gst.caps 类型，我如何从中获得实际的宽度和高度？

If running your pipeline by gst-launch-1.0, you can actually see the caps negotiation by putting GST_DEBUG=7 before gst-launch-1.0.如果通过 gst-launch-1.0 运行管道，您实际上可以通过在 gst-launch-1.0 之前放置 GST_DEBUG=7 来查看上限协商。 However, GST_DEBUG=5 may get you the information you need without the huge amount of trace information given by GST_DEBUG=7.但是，GST_DEBUG=5 可能会为您提供所需的信息，而无需 GST_DEBUG=7 提供的大量跟踪信息。
