@seka OK~

@watchever Do you use VEYE-MIPI-IMX462 ? I think it do not support other resolutions other than 1080p. http://wiki.veye.cc/index.php/VEYE-MIPI-IMX462_Data_Sheet This is a limitation of ISP.

Ok got it. I confirm output format is I420 and array order is correct. Thanks for your help

@hezudao 不客气~

@veye_xumm 由于时间太久了,客户没有进一步的反馈,我会把这个帖子标记为已解决.

@watchever Hi, it is the ISP limit which VEYE-MIPI-IMX462 used.

@seka 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 ， http://wiki.veye.cc/index.php/VEYE-MIPI-290/327_i2c/#yuvseq 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.
