Question about scaling issue on old device

[mrtndat]

Hello,
I notice on old devices which has Camera levelSupported is CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY. The width and height must be in the supported list.
When I pass a width and height of 960x540 on that device, but the prepare() function return false. I have to make a workaround that find the nearest support camera resolution, in the above device, the nearest one is 800x480.
This time, the camera functions are working fine. However, the image is scale. I have tried the setAspectRatioMode(AspectRatioMode.Fill) but it does not work. See the below video.

Is there a way to output the 960x540 video on device that does not support this resolution?
Thanks

Hello,

It is not supported because that devices use a wrapper of camera1 API which can't open any resolution.
I can try find a way to do it with Camera2Source but only if the device support a resolution with the same aspect ratio and higher than the selected resolution

Can we open the camera with supported camera resolution on those device (800x480), but keep the encoder use the input resolution (960x540)?

btw, I have updated my workaround to find the nearest support resolution with the same ratio.
This time, the camera is opening with no scale issue.
Thanks

This has no sense according with my previous explanation of aspect ratio. That resolutions have different aspect ratio

Got it, then I will stick with my workaround on those devices.
Thanks
