Subject: [PATCH] drivers: meson: vdec: add VP9 support to GXM
Date: Wed, 9 Feb 2022 15:31:50 +0000 [thread overview]
Message-ID: <20220209153150.30688-1-christianshewitt@gmail.com> (raw)
VP9 support for GXM appears to have been missed from the original
codec submission [0] but it works well, so let's add support.
[0] https://github.com/torvalds/linux/commit/00c43088aa680989407b6afbda295f67b3f123f1
Signed-off-by: Christian Hewitt <christianshewitt@gmail.com>

Tested with LibreELEC 11 nightly 'AMLGX' dev images for Khadas VIM2
and WeTek Core2 GXM devices which can be found here [1]. The images
combine Linux 5.16.y [2] with Kodi v20 [3] and FFmpeg 4.4 [4] which
notably includes many V4L2 refinements for stability and usability.
