From 7aea2c0b48a568e6732c1d30516febe36bf555f1 Mon Sep 17 00:00:00 2001 From: Michael Tretter Date: Wed, 8 Sep 2021 14:03:15 +0100 Subject: media: allegro: add control to disable encoder buffer The encoder buffer can have a negative impact on the quality of the encoded video. Add a control to allow user space to disable the encoder buffer per channel if the VCU supports the encoder buffer but the quality is not sufficient.
