1, Test server configure:
[root@localhost ~]# cat /proc/cpuinfo  |grep "model name"
model name	: Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz
model name	: Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz

              Mem:           102G        1.1G        100G         16M        657M        100G
              Swap:          4.0G          0B        4.0G

2, Test result:
encode the v410 input data for testing:
 ./ffmpeg -y -i 4k_422.ts  -c:v v410 -vframes 10 test.avi
