2017-07-07 18:45 357 查看

背景

我使用的机子的配置Intel(R) Core(TM) i5-5250U CPU @ 1.60GHz 4核 8G内存 120G硬盘

测试方式， 使用intelGPU 1080p yuv 数据文件， 读取编码并写到264文件中， 这里涵盖了IO操作

测试

命令举例

suirui@suirui:~/github/intelencode/bin$ ./EncodeVideo
./EncodeVideo process_no(0,10]
suirui@suirui:~/github/intelencode/bin$ ./EncodeVideo 1
process yuv test_1920_1080_1.yuv  h264 1.264
