1.使用贵公司sdk，烧写的系统，文件系统是qt版本的；
2.测试命令：gst-launch-1.0 v4l2src device=/dev/video0 ! vpuenc_h264 ! rtph264pay ! udpsink host=192.168.1.111
打印如下：

3.命令是参考：《i.MX_Linux_User's_Guide.pdf 》使用gstramer 测试，只要涉及vpuenc_h264这个插件，都会报错。
请给一个解决问题思路。

重新烧写了打了补丁的的sdk，文件系统是L31452-fsl-image-qt5-myimx6a9.tar.bz2,但是启动后的界面是个字符终端，而且usb 摄像头打开都失败了 /dev/video0 和/dev/video1 都是打开失败
