@大法师
安装U盘和备份U盘都可以用
刚做好的安装U盘是可以刷系统 就是安装镜像里面的系统
备份u盘是可以备份系统 backup可以备份出系统
但是把备份U盘中backup文件夹的内容 拷贝到安装u盘的install文件夹中
安装U盘不能还原系统 -

@大法师
是不是新的系统备份出来的不能 旧的系统备份出来的才能还原
可以试试0613的系统备份出来的 能不能还原 -

@大法师
新做的安装盘可以刷系统
备份盘的backup更新到安装盘的install目录下 就刷不了系统 直接就进系统了
有没有详细操作过程 到底怎么操作才能保证能刷 -
ffmpeg编码器支持posted in Pi 4B
ffmpeg的编码是不是不支持mpp的h264、h265编码
我看了gst的是有mpph264enc
ffmpeg的就只有软编码
是不是没有集成进去
