[libcamera-devel] [RFC PATCH 0/6] Support stream mapping in Android HAL adaptation layer

[Hirokazu Honda]

+Jacopo Mondi +Laurent Pinchart

Hello Jacopo and Laurent (sorry for pointing fingers), as you have
joined with my previous proposal discussion, may I please ask you to
review this patch series?
I don't at all intend to submit the patch series at one time.
I would like to hear your opinion about this direction.
Some of them might be reasonable to submit shortly as they generalize
the post processing code.


Thanks so much in advance,
-Hiro
