These formats were prefixed with "planar" indicating I & Q data are not interleaved as in other formats. Here, I & Q data constitutes the top half and bottom half of the received buffer respectively. V4L2_SDR_FMT_PCU16BE - 14-bit complex (I & Q) unsigned big-endian sample inside 16-bit. V4L2 FourCC: PC16 V4L2_SDR_FMT_PCU18BE - 16-bit complex (I & Q) unsigned big-endian sample inside 18-bit. V4L2 FourCC: PC18 V4L2_SDR_FMT_PCU20BE - 18-bit complex (I & Q) unsigned big-endian sample inside 20-bit.
