Work around codec frame rate issues in Redmi Note 9 Pro

The decoder and encoder won't accept high values for frame rate, so avoid
setting the key when configuring the decoder, and set a default value for the
encoder (where the key is required).

Also skip SSIM calculation for 4k, where the device lacks concurrent decoding
support.
