ITX-3588J使用HDMI_RX端口,如何全屏显示?
ITX-3588J使用HDMI_RX端口,HDMI_RX端口连接笔记本。输出界面有仍然有边框,如何将笔记本视频信号全屏显示呢?如附件图片所示。你是怎么实现的?用的是gstreamer吗?gstreamer的话需要使用kmssink管道显示输出。 是使用gstreamer 我们使用gst-launch-1.0 v4l2src device=$device_id ! queue ! video/x-raw,format=BGR ! capssetter replace = true caps="video/x-raw,format=BGR,width=$width,height=$heigh" ! glimagesink &命令。
请问使用kmssink管道显示的命令是什么样的? glimagesink 换成 kmssink 试试 不行,打印如下:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

在debian11系统上面试一下 hejinyi 发表于 2022-10-31 16:20
