About BitmapFactory.decode File in Android4.4.3 BSP for i.MX6-SABRE

yuuki — Thu, 07 Apr 2016 07:12:18 GMT

Dear all,

We use the Android4.4.3(NXP's BSP) on MX6Q-SABRE-SDB board.

We want to decode JPAG file by using Android's API.

- BitmapFactory.decode File

Does this API use hardware Video Codec(VPU)?

If it does not use VPU, Could you tell me how to use VPU by this API?

Best Regards,

Yuuki

decoding jpeg uses software decoding in current android bsp, not vpu.

you can referr to the release note to check if software support this or not.

Dear Guanqiong Xie-san,

Thank you for your support.

Could you tell me how to decode JPEG by hardware?

I understand that JPEG decode of VPU supports only Baseline profile.

Is my understanding is correct?

Best Regards,

Yuuki

current bsp uses software decoding, if you need to use VPU, you need create your own application to call the vpu.

yes, supports baseline.
