Gstreamer gst-launch-1.0 videotestsrc！自动视频接收器不'；t工作（va错误）,gstreamer,gstreamer-1.0,Gstreamer,Gstreamer 1.0,我有ubuntu 16.04。我已尝试通过本教程安装gstreamer：但它对我不起作用（找不到包裹）。所以我试着用这个： list=$(apt-cache --names-only search ^gstreamer1.0-* | awk '{ print $1 }' | grep -v gstreamer1.0-hybris) sudo apt-get install $list 安装gstreamer后，我通过以下方式测试了它的工作原理： gst-launch-1.0 videotes

我有ubuntu 16.04。我已尝试通过本教程安装gstreamer：但它对我不起作用（找不到包裹）。所以我试着用这个：

list=$(apt-cache --names-only search ^gstreamer1.0-* | awk '{ print $1 }' | grep -v gstreamer1.0-hybris)
sudo apt-get install $list

安装gstreamer后，我通过以下方式测试了它的工作原理：

gst-launch-1.0 videotestsrc ! autovideosink

得到了这个日志：

可能是我安装的gstreamer不正确。如果您知道如何正确操作，请回答。

看起来您有一张nvidia卡。Gstreamer试图使用硬件解码，但失败了——可能是因为驱动程序和硬件不能很好地协同工作

尝试卸载

gstreamer vaapi

软件包。然后FFmpeg插件应该进行编码（如果已经安装）。一旦开始，你可以在以后的阶段考虑硬件解码选项。

< P>我只需重新安装OpenCV LIB（它有gStuffER在内部）

< P>由于某种原因，接收器不能与NVIDIA卡一起工作。Nveglessink为我工作：

gst-launch-1.0 videotestsrc ! nveglglessink

由于某些原因，接收器不能与NVIDIA卡配合使用。Nveglessink为我工作：

gst-launch-1.0 videotestsrc ! nveglglessink

谢谢你们的回答，但我已经修复了它（我重新安装OpenCV库，它对我有效）谢谢你们的回答，但我已经修复了它（我重新安装OpenCV库，它对我有效）
