If the user has selected a custom bitrate, we will leave it alone.

// support YUV444 streaming, use the default non-444 bitrate for the stream instead.
// This should provide equivalent image quality for YUV420 as the stream would have
// had if the host supported YUV444 (though obviously with 4:2:0 subsampling).
// If the user has adjusted the bitrate from default, we'll assume they really wanted
// that value and not second guess them.
