【分享】以H.265 1080p 运行 Xilinx Low Latency PL DDR XV20 HDMI Video Capture and Display
运行 Xilinx Low Latency PL DDR XV20 HDMI Video Capture and Display，可以测试HDMI输入输出，和VCU的低延时编码。Xilinx wiki的文章MPSoC VCU TRD 2019.2 - Xilinx Low Latency PL DDR XV20 HDMI Video Capture and Display以H.264和4K分辨率为例。
下面记录H.265和1080p分辨率的运行命令。
首先设置HDMI输入，保证输入分辨率是1080p。我使用电脑Dell 5580作为ZCU106单板的HDMI输入源。电脑Dell 5580上看到两个显示器，一个是真实显示器，一个是ZCU106单板的HDMI输入。虽然我在电脑Dell 5580设置ZCU106单板的HDMI输入为1080p，但是在ZCU106单板使用命令“xmedia-ctl -p -d /dev/media1”查看，HDMI输入的分辨率一直是4K。后来把电脑Dell 5580的输出模式从扩展(Extend)改为复制(Duplicate)后，在ZCU106单板才看到HDMI输入的分辨率是1080p。这一点很莫名其妙。

接下来设置ZCU106的VPSS的分辨率和格式。设置后，再使用命令“xmedia-ctl -p -d /dev/media1”查看，所有pad的分辨率信息都是1080p了。

使用命令“modetest -D a00c0000.v_mix -s 35:1920x1080-30@BG24”，设置设置HDMI输出分辨率。设置时，会产生异常，可以暂时忽略。设置后，HDMI显示器会显示蓝屏。
