Subject: [PATCH 04/14] Add support for V4L2VDA on Linux
This patch enables hardware assisted video decoding via the
Chromium V4L2VDA. Including changes when Linux is used. In
order to use this, use_linux_v4l2_only flag should be set
to true.
Signed-off-by: Ryo Kodama <ryo.kodama.vz@renesas.com>
fixup! avoid building not declared formats
"FRAME", "_SLICE", "V4L2_PIX_FMT_VP9" are not defined in mainline
Linux headers. This patch avoids building these formats.
Signed-off-by: Ryo Kodama <ryo.kodama.vz@renesas.com>
fixup! add V4L2_PIX_FMT_VP9 support back again as it is now
included in mainline Linux kernel. This allows VP9 codec
to work with upstream kernel and v4l2 vda. Tested on db820c
with Venus v4l2 driver.
