    Use hybrid RD and non-RD coding flow for key frame coding · 07711e9b

    When block size is below 16x16, the encoder swap from non-RD to
    RD mode for key frame coding. This largely brough back the key
    frame compression performance. For vidyo1 at 1000 kbps, the key
    frame coding statistics are changed
    9978F, 34.183 dB, 36807 us -> 9838F, 35.020 dB, 61677 us
    As compared to the full RD case
    7187F, 34.930 dB, 214470 us
    The overall rtc set coding performance (single key frame setting)
    is improved by 1.5%.
