hello

  我安装intel media sdk R6版本在ubuntu 上， ubuntu是14.04.3

uname -a

Linux suirui 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

我安装文档的generic 的方式安装的， 然后编译sample MediaSamples_Linux_6.0.16043175.175， 产生了sample_encode_x11 bin文件， 然后我使用命令./sample_encode_x11 h264 -i test_stream_176x96.yuv -o 3.264 -w 176 -h 96  -vaapi

第一次运行正常， 产生了h264文件

第三次再运行该命令又正常了， 我查了一下该错误， 是MFX_ERR_LOCK_MEMORY, 是什么原因产生的？
