Hello nxp

    Using USB camera on imx8mq often can't be opened.here is the log infoour memory 2G Android8.1

    Opening the UVC camera is very slow. It will take a picture automatically for the first time。Android 8.1/9.0 has such problems。Is there any way to solve this problem。 thanks!

Hello,

According to the Android release notes. The only USB cameras that are supported are the following ones.

Logitech:

  • C920
  • C270
  • C525

Please make sure that you are using one of those USB cameras.

Best regards,

Diego.
