AM625: am625 version 09.00.00.03 Add csi interface camera

Hi Tip,

Our CSI expert is out of office today. Please expect delayed response.

Hello,

Do you see a similar issue with kmssink?

Regards,
Krunal

Hi,Krunal:

Yes,the same problem exits with kmssink.

Hi Tip,

Could you run the command "media-ctl -p" and share the output?

Thanks,

Jianzhong

Hi Jian，

The following is the output of this command：

Hello Tip,

Thanks for sharing the log. Can you try to configure the csi bridge to have the same format as the sensor?

media-ctl -V '"cdns_csi2rx.30101000.csi-bridge":0/0 [fmt:UYVY8_2X8/1920x1080 field:none]'

Please run a "media-ctl -p" to verify the csi bridge has the same format as the sensor. Then run the streaming and see if it works.

Regards,

Jianzhong

HI Jianzhong,

Thank you for your reply, but I don't quite understand what you mean, my csi bridge and sensor format is the same before executing the command you gave. Nothing changed after changing it.

I'm not too familiar with the operations related to video streaming, so please advise me!
