gstreamer使用rkximagesink出现问题

[复制链接] · 发表于 2019-11-1 13:11:16

我的是tb-rk3399pro开发板，fedora系统，1.5版本的固件，下载了gstreamer-rockchip，在执行autogen.sh的时候，没有安装vpudec

安装完成后，用gst-inspect-1.0 rockchipmpp rkximage，有显示相关信息

但是我使用命令：gst-launch-1.0 -v videotestsrc ! queue ! videoconvert ! rkximagesink，只显示了一个黑屏，没有图像，log如下所示

请问下这是什么原因，谢谢！
