Hi,

I wanted to know if it was planned to have the ZSL working with the torch enabled ? And also why the ZSL don't work with CameraControl.enableTorch(true).

Thanks a lot !

Hi Val,

Currently we don't have plan to support ZSL with the flash enabled. 

The reason is the flash sync logic in CameraHAL is pretty tricky, probably not possible to implement customized logic for ZSL. 
One alternative is to set the flash mode to torch the whole time but this is not recommended (flash is not running at full power so the amount of lighting is limited).

So we are disabling ZSL when flash mode on now.

Best,
Kailiang

Hi,
Thanks for the response.

"One alternative is to set the flash mode to torch the whole time" I don't understand this, the torch should work with ZSL ? or the flash == torch ?

Hi Val,

The ZSL should work with torch (if flash mode is OFF).

Best,
Kailiang
