Questions about Android Automotive EVS

[jumogehn]

Hello,

I've got questions about EVS in Android Automotive as shown below:

I am using i.MX 8QuadMax MEK.

The word evs_app is the one from the User Guide.

1. How long will it take for evs_app to finish initializing and start running?

2. Is there a significant difference in the time between booting and completing initialization when evs_app is compared to a regular Android service?

3. What video/audio encoder APIs can be used in evs_app? We are trying to develop a dash cam using this API. Will these APIs use HW encoders?

4. I am trying to develop a dash cam in the form of evs_app. The reason is that it is considered a solution to the quick time constraints from booting to initialization. Is this really a good idea?

Thank you very much in advance!

Hi @jumogehn, 

Thank you for contacting NXP Support.

I don't have information about the time or benchmark of EVS APP.

Regarding EVS_APP development, please have a look to the NXP Android Automotive User's Guide and the official Android documentation:
Vehicle Camera HAL  |  Android Open Source Project

I hope this information will be helpful.

Have a great day!
