Enable mode search threshold update in non-RD coding mode Adaptively adjust the mode thresholds after each mode search round to skip checking less likely selected modes. Local tests indicate 5% - 10% speed-up in speed -5 and -6. Average coding performance loss is -1.055%. speed -5 vidyo1 720p 1000 kbps 16533 b/f, 40.851 dB, 12607 ms -> 16556 b/f, 40.796 dB, 11831 ms nik 720p 1000 kbps 33229 b/f, 39.127 dB, 11468 ms -> 33235 b/f, 39.131 dB, 10919 ms speed -6 vidyo1 720p 1000 kbps 16549 b/f, 40.268 dB, 10138 ms -> 16538 b/f, 40.212 dB, 8456 ms nik 720p 1000 kbps 33271 b/f, 38.433 dB, 7886 ms -> 33279 b/f, 38.416 dB, 7843 ms Change-Id: I2c2963f1ce4ed9c1cf233b5b2c880b682e1c1e8b
