Android Question Allocate larger buffer stream for Camera Output Result Queue

[Delahaye]

In the optic of delaying the preview of the camera, I've read some (very interesting) articles on the process of the camera.

https://source.android.com/devices/camera/camera3.html
https://source.android.com/devices/camera/camera3_requests_hal.html#

It show that there is a :

1 Request Buffer Queue
N Output Gralloc Buffer Queues
1 Output Result Queue

I'm interested in increasing the Output Result Queue
I saw that in Camera2.h there is some types on buffer queues (Line 259) and some info on Allocating Buffer streams

http://source.android.com/devices/reference/camera2_8h_source.html
Line 585 : Allocate_stream

Can I use this in a B4A project ?
Or How could I increase the result queue of the camera ?

thank you

This is Android native source code. This code can only be changed if you are building Android yourself.
You should search for a Java API that changes this buffer.

Is there a Java Api "Bank" somewhere ?
Knowing what I'm trying to do, as an Expert, Erel, do you think I'm dereasonnable ?

Yes. Though it will be easier to just search google.

I don't think that it is possible to add such a delay this way. However I haven't investigated it.
