[PATCH 2/7] media: mediatek: vcodec: Setting the supported h264 level for each platform

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The supported resolution and fps of different platforms are not the
same. Need to set the supported level according to the chip name.
