Gstreamer错误:无法构造管道:没有元素"v4l2src" [英] Gstreamer Error: pipeline could not be constructed: no element "v4l2src"

问题描述

我正在使用Ubuntu(14.04)，尝试使用gstreamer时出现此错误.

Am using Ubuntu(14.04) and I am getting this error while trying to use gstreamer.

gst-launch-1.0 v4l2src !  video/x-raw,width=640,height=480 !  x264enc ! h264parse ! rtph264pay !  udpsink host=127.0.0.1 port=5000

我已经检查了gst-inspect-1.0 v4l2src

I have checked the gst-inspect-1.0 v4l2src

它说找不到元素没有这样的元素或插件'v4l2src'"

It say element not found "No such element or plugin 'v4l2src'"

我该怎么办?从哪里可以得到这个元素或插件.我尝试重新安装整个gstreamer.但是我无法这样做.

What should I do ? From where can I get this element or plugin. I have tried resinstalling entire gstreamer. But am unable to do so.

推荐答案

v4l2src插件属于gstreamer-plugins-good软件包；所以

the v4l2src plugin belongs to the gstreamer-plugins-good package; so

sudo apt-get install gstreamer1.0-plugins-good

应该帮助您

Gstreamer将大多数插件打包在单独的软件包中；你有

Gstreamer packages most of its plugins in separate packages; you have

• gst-plugins-base
• gst-plugins-good
• gst-plugins-ugly

等等.它们是可插拔的；因此，仅更新gstreamer不会自动选择对您有利的gst-plugins ...

and more. They are pluggable; so just updating gstreamer won't auto-select gst-plugins-good for you...
