x264.exe -o out.h264 my_movie.ts

3. Download and compile codecs

Http://software.intel.com/en-us/articles/intel-integrated-performance-primitives-code-samples/

Open a CMD and enter (My IPP is installed on the edisk ):

Set ipproot = E: \ Program Files \ intel \ composer Xe 2011 SP1 \ IPP

Browse the directory extracted from the sample and go

IPP-samples \ audio-video-codecs \ Application \ umc_h1__dec_con \

IPP-samples \ audio-video-codecs \ Application \ umc_video_enc_con \

Drag the sln files in these two directories to the CMD file (in fact, it is to set the environment variable ipproot when the SLN is opened)

After compilation, two EXE files are obtained:

Umc_video_enc_con.exe

Umc_h1__dec_con.exe
