Use hybrid RD and non-RD coding flow for key frame coding 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%.
