gstreamer opencv edgedetect [英] gstreamer opencv edgedetect

问题描述

我想在 gstreamer 中使用 edgedetect.我之前检查过gst-inspect.这是我的结果:

I want to use edgedetect with gstreamer. I check with gst-inspect before. This is the result I have:

login@machine:~$ gst-inspect opencv
No such element or plugin 'opencv'
login@machine:~$ gst-inspect edgedetect
No such element or plugin 'edgedetect'

安装的插件是:

sudo apt-cache show gstreamer1.0-plugins-bad | grep Version
Version: 1.0.3-1~ubuntu12.04.1~ppa1
Gstreamer-Version: 1.0

opencv"插件必须在插件坏.我可以使用包含在 plugin bad 中的其他插件启动 gst-inspect，但不能使用 opencv 或 edgedetect.

"opencv" plugin must be in plugin bad. I can launch gst-inspect with other plugins included in plugin bad, but not opencv or edgedetect.

我尝试从源代码安装插件，没有任何变化.

I tried to install the plugin from the source code, nothing has changed.

推荐答案

今天如果你想使用描述的 GStreamer OpenCV 插件 这里 和 这里 你只需要做的是:

Today if you want to use the GStreamer OpenCV Plugins described here and here you just need to do is:

sudo apt install gstreamer1.0-opencv

如果您想检查 edgedetect 插件是否可用(以及其他插件):

要测试它是否工作正常:

To test if it works fine:

$ gst-launch-1.0 videotestsrc ! videoconvert ! edgedetect ! videoconvert ! xvimagesink

它在我的 Jetson Nano 4Gb 和 Jetpack 4.5.1 上运行良好.

It worked very well on my Jetson Nano 4Gb with Jetpack 4.5.1.
