@veye_xumm

You do not need to use gstreamer.

So how can I connect and display four cameras?
Please direct me to the answer from among all the possibilities.

Or are you stating that you can for a phenomenon that has never been realized?

@wudecao
这个问题暂时我没有思路。你如果愿意，可以把你的agx寄到我公司，我尝试追踪解决一下。
私信我，会给你邮寄地址。

@thestaticturtle
Thank you for the valuable advice.
I took a brief look at the code of the raspindi project you mentioned, and this is basically a simplification and modification of the raspivid base. The calls to NDIlib are added. Of course, this is a c++ program.
Based on our veye_raspivid, I think it is feasible to do some porting work.
But our software engineers are very busy now, so it will take some time to arrange this.

Sorry reply finished. China took a 7 day holiday. We just got back to work.

There is no tab in front of FDT.

@freshman 不客气。

@dan_lionking
Please try this:
Add the bellowing line to the end of veye_mipi_i2c.sh

./i2c_write $I2C_DEV $I2C_ADDR 0x07 0xFF&> /dev/null;

I think this will solve your problem.

@maponarooo You are welcome.

@hezudao
我这里maaxboard老化了两天，没啥问题。

现在停止这个老化实验，期待你的新结果。

@watchever
Sorry, this can not be modified. IMX307 is slightly worse than 327 low illumination, but the actual difference is not very large.

headless

Sorry, I'm not sure.

@tuzi
你好，我们的摄像头模组，并没有使用nvidia的isp，而是使用的摄像头自带的isp。所以你调英伟达的参数，当然不能生效。

我们的isp是通过一个脚本直接控制寄存器进行调节的。
强光下，你可以试试DOL宽动态：

@watchever
Hi,
For VEYE-MIPI-327E, which is 2 boards,5V is necessary.
For VEYE-MIPI-IMX327S, which is 1 board, 5V is not necessary.

@jdx-jdx
是的。probe成功才会生成video节点。

@tuzi said in veye imx327:

nvoverlaysink

可以给nvoverlaysink加个参数，控制一下显示区域。或者换一个其他sink试一下。

我暂时不能直接提供答案，你可以参考英伟达这个部分的文档略作研究。

@g-towboat
Our solutions are 953 and 954 and the source code of the driver is provided. You can refer to this source code to support 964.
Now fpdlink products have been suspended due to chip out of stock, sorry.

@stiwana

@stiwana said in Low light MIPI camera supporting 720p60:

Is it possible to output HDR imagery over the MIPI interface (IMX327S/IMX385/IMX462) or do we need to do it inside our own fpga?

These 2 modules support DOL HDR inside. You can enable this function via shell script.

Is the I2C command set open, such that we could do the camera module configuration from our baremetal application?

Yes, the I2C toolkit is open source.

Can you confirm my understanding that in this case our FPGA will be talking to the onboard ISP chip on your camera board over I2C, and not directly to the camera.

YES. Directly to ISP and my FPGA, not to sensor.

Roughly how much is the added latency due to your onboard ISP on the boards?

60-80ms I think. Because DOL WDR and 3D denoise functions.

The auto exposure and white balance will be handled by the onboard ISP, and will not need to be handled by our FPGA, correct?

Yes.

@veye_xumm 好的，谢谢您

Ok, will connect wire from IRLED to gpio.
