While the decoder can produce frames in both MM21 and MT21C formats, only MM21 is currently supported by userspace tools (like gstreamer and libyuv). In order to ensure userspace keeps working after the SCP firmware is updated to support both MM21 and MT21C formats, force the MM21 format for the capture queue. This is meant as a stopgap solution while dynamic format switching between MM21 and MT21C isn't implemented in the driver.
