I'm not very familiar with python. But in my opinion, jpeg is compressed data, which can't be subset by simple sampling, is it?

@xsw
很好。
硬件是被动的，软件是主动的。
摄像头不能去操作主板的内存，是靠主板上的软件来操作摄像头，把数据放到内存。
树莓派是上我们提供的两种应用模式，都可以由软件获取到摄像头输出的数据。
请参考详细的文档和代码。

@veye_xumm 哦，好的，那可能是采购给我的型号弄错了，我用327的dtb再试一下，谢谢了

@dan_lionking
You are welcome.

@watchever
I think what you mentioned is mshutter. Yes, of course.
mshutter :
If you use manual mode, the exposure time will be independent of the ambient brightness.

@watchever
For yuv ，

And I'm sorry , can not provide you such python code now.

@watchever
You are right.

@watchever
Yes. VEYE series does not support exposure time longer than 1 second.
CS series support this feature.

Thanks xumm I have add rpi3-gpiovirtbuf initialize routine in the libdmipicam.so library, so don't need to run this binary alone and it works.
Thanks

@watchever
yes,you are right.

@veye_xumm 明白了，谢谢！！

@veye_xumm OK, thanks. Solved it by adding vc.ril.hvs component before h264 encoder and doing some fancy overlays by libcairo.

@seka
hi, VEYE-MIPI-IMX462 do not support YUV 10BIT/12BIT.

@veye_xumm Ok, thanks.

@dan_lionking
Right. That's the result.

@seka
Thank you for sharing.

@veye_xumm Thank you Xu, downloaded the new file and now it is working like a treat!

已与瑞泰沟通驱动移植事宜。

@veye_xumm Thank you! That made it clear to me

@eledog
我们装了一个你用的lite版本，运行是没有问题的。

你用的硬件是4GB版本，我们的是2GB版本。

我这没法重现的情况下，你可以尝试103-123行进行逐行注释来找一下原因。
