From 275ce8667a725d37a22b726fbd64a785243b6d9a Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Fri, 15 May 2020 13:48:59 +0100 Subject: [PATCH] staging:vc04_services: bcm2835-camera: Request headers with I-frame V4L2 wishes to have the codec header bytes in the same buffer as the first encoded frame, so it does become 1-in 1-out for encoding. The firmware now has an option to do this, so enable it.
