【芒果派MangoPi MQ Quad】+芒果派初次折腾

收到芒果派之后我看了一下这块板子的基本情况
拿到手以后尝试着使用hdmi连接到自己的便携显示器上面，发现这块板子是mini hdmi，我的便携显示器也是mini hdmi，然后就买了一条双mini hdmi口的线，现在是能连接上了。
其实我是想装一个ffmpeg到这块板子上的，但是官方提供的镜像似乎默认并不能直接用openmax跑，可是看datasheet上面介绍的还是挺全的。

看芯片是h616，是allwinner的，那么他的codec如果想要支持的，应该是可以考虑用 https://linux-sunxi.org/sunxi-cedrus 来支持。
但是配置sunxi-cedrus还是比较费劲的，所以可以先试试编译一个ffmpeg来感受一下。
只跑低分辨率的mpeg2的话问题不大，但是分辨率稍微高一些可能就不行了，其实主要还是得上h264的编码器，并且还是要用硬件编码器。

看上去硬件加速器只有vdpau可以支持。

开机第一件事肯定是希望能连上个网，然后用自己的高配电脑可以ssh登录到这块板子上，毕竟这块板子上跑界面还是比较慢的。
目前这块板子上的硬件视频编解码能力还有跑起来，allwinner的芯片好像硬件视频编解码器跑起来比较折腾，可能需要自己重新build一个镜像。这个过程比较漫长，我继续去build了。
