Subject: media: mediatek: vcodec: Set the supported h265 level for each platform
Author: Yunfei Dong <yunfei.d...@mediatek.com>
Date: Mon Oct 23 11:06:36 2023 +0800
Set the maximum H265 codec level for each platform.
The various mediatek platforms support different levels for decoding, the
level of the codec limits among others the maximum resolution, bit rate
and frame rate for the decoder.
