@veye_xumm 那是否也能把 power_line_frequency 也放進去支援 60hz ? 或是如果是特製版，那能直接把預設做成 60hz 嗎？

@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。

参考第二步。
执行完之后，试一下

i2cdetect -y 10

如果看到有0x3b，则说明i2c配置的对，而且已经检测到摄像头了。

否则请检查一下硬件连接，注意排线方向。

@imagidan
I can't get effective help information about this log.

I have two possible suggestions.

Update both Image and dtb, but this approach probably won't solve the problem. Recompile from the code according to the following link. You can compile the standard version, test it, then add our driver, and then test it after compilation.

I find it strange because this version of Image is already used by so many customers.

@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.

@coolmitch
每次都要设定一下。 对应的linux下指令，暂时还提供不了给你。

@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

@fabricio-borges
hi，
I think this is normal, the VEYE series of cameras do not have the ability to save parameters. Therefore, each power outage causes the parameters to return to their default values.

@r-l
你好。
你的操作没有问题，现在要检查问题在哪。

CS-MIPI-IMX307是支持FFC排线直接供电的，而且我们出厂默认是这种模式，建议不要额外插5V。 如果万一插反，有可能烧坏。
http://wiki.veye.cc/index.php/Power_supply_mode_switching/zh 可以用命令检测i2c是否能找到摄像头(0x3b)地址。 sudo i2cdetect -y 9 sudo i2cdetect -y 10

感觉不太妙，你这个摄像头有已经烧坏的可能。

@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.
