IMX6q + android 6.0 + USB Camera 13M issue

mackwu — Thu, 06 Apr 2017 01:48:43 GMT

Hello all

I tried using a 13M USB camera(e-CAM130_MI135_MOD 13MP AR1335 camera module) in android 6.0.1_2.1.0.

When i execute the camera app,no show any screen.At the same time i went to check logcat to get the following message.
It seems that it does not support MJPEG and UYVY format.
Is it possible to support MJPEG or UYVY format in IMX6 with android 6.0?

Accordingly to i.MX Android Extended Codec Release Notes Android 6.0 does support mjpeg codec for video decoding.
However please note that mjpeg subtypes and MJPEG_2000 and MJPEG_B are not supported.
Only YUV420 and YUV422 (horizontal) color formats are supported.

Have a great day,
Victor

Hi, All

I also have simlar issue. We update the OS from android4.x to android6

Now, we need decoding of mjpeg and YUV for the video streaming

I am not sure what Victor mentioned is mjpeg is not supported by imx6 with android6 now or ?
