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

I would suggest the following rewording:

Set the maximum H264 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.

With that you can add:
