V853 的视频输出方式通过 8pin RGB serial 的方式输出bt656 的数据格式，发现vsync的能力只有最大支持500多的高度，无法传输1080p 25Hz的图像。请问8pin RGB serial 的方式在v853 的硬件上支持1080p 25hz 的输出吗？

逗

v853 的mpp 的vi 或者vo插件能够进行对画面的放大吗？

@whycan 在录制视频文件，断电后文件大小变为0KB 中说：

fsync( )

fsync( ) 操作在哪执行呢？

逗

使用录制视频文件，断电后文件大小变为0KB，保存的文件格式是ts

逗

isp 的部分也会打包进去嘛？

逗

V853S的最大支持的LCD 屏幕的时钟频率是多少呢？

逗

摄像头是1080P 60fps的输出，使用vi来进行获取，然后通过非bind的方式连接到vo上，但是发现在画面移动的情况下，显示屏的画面有卡顿和丢帧的情况？是使用了ISP的，我猜想是不是ISP的问题呢?还是说v4l2框架需要配置呢？

如果直接使用bind模式，卡顿效果会有改善，偶尔还是会有这样的情况。

@xiaowenge 如何降低，mpp的功耗呢？

@rain_tk 感谢大佬的回答

逗

@xiaowenge 是在make_menuconfig中去掉，boot up colobar选项即可

逗

使用mpp中的 AW_MPI_VI_SetVippFlip，无法对屏幕进行翻转

逗

@xiaowenge 是的，已经解决了哈

在驱动之后，屏幕总是出现彩色条纹，这个是什么原因呢？在什么地方可以关闭该条纹的显示呢？

@w2836833 我也想知道呢？

@whycanservice 是使用non-tunnel 模式进行组件的连接嘛？

从软件上我确保我的数据已经发出来了，如图所示：

 ier  : 0x05
 lcr  : 0x13
 mcr  : 0x03
 fcr  : 0xb1
 dll  : 0x0d
 dlh  : 0x00
 last baud : 115384 (dl = 13)

TxRx Statistics:
 tx     : 351
 rx     : 68210
 parity : 0
 frame  : 0
 overrun: 0
 throttled: 0

同样的串口编程的代码放在了jetson开发板上进行使用，发现TX数据是正常的
怀疑是TX硬件可能有其他的电路，看了一下开发板原理图，但是和PCB无法进行对应上所以没法进行确定
开发的编号是 22052300 2224
