No EGL Display 报错解决

版本情况如下
CUDA版本：10.2

tensorrt版本：8.0.1.6

JetPack版本：32.6.1

deepstream版本：6.0

官网的系统版本适配图如下：

通过对比发现：我的版本是没有问题的。于是开始细细地检查报错。

第一种类别报错
报错如下

nvbuf_utils: Could not get EGL display connection
No EGL Display
nvbufsurftransform: Could not get EGL display connection
No EGL Display

解决方法，在命令行执行：
unset DISPLAY
rm ${HOME}/.cache/gstreamer-1.0/registry.*

输入上面的命令的目的是：将DISPLAY的值设为:0。

可以输入以下的命令查看：

echo $DISPLAY

# 输出为 :0

如果上述的命令并没有将DISPLAY的值设为0，请使用下面这种方法：

export DISPLAY=:0

然后再次输入命令查看：

echo $DISPLAY
# 输出为 :0

其实第一类报错算是已经解决了。

再次输入：

gst-inspect-1.0

发现报错减少了，但是还有4个：

说明第一类的报错已经解决了。

第二类报错

通过这篇文章发现，这些问题是Deepstream6.0所为解决的问题，可以忽略。

重新推理，得到正确的结果了。
