S tarti ng the S ta ndalone D emos Runnin g the De monstrati on Softwa re 3-3 ❏ Command line. Once yo u have co nnected the EV M to a worksta tion and ins talled the ne ces sar y so ftware ( as de scr ibe d i n S ecti on 4.3.1 , Installing th e T arg et Linux Software ), you ca n run the dem os from th e board’s Linux comman d line.
S tarting the S tand alone Demos 3-4 Once th e EVM b oard has b ooted, your v ideo display sho uld show a pic ture of the r emote control . Y ou use t he IR remote to control the demos.
Runni ng the S tanda lone Demos Runnin g the De monstrati on Softwa re 3-5 3.3 Running the Standalone Demos 1) Press "Play" or "OK" on the remote to move fro m the rem ote control diagram to the m ain menu s creen, which lo oks like t his: The Encod e + Decod e demo a llows y ou to rec ord and p layback video.
Runni ng the S tanda lone Demos 3-6 8) Thi s inform ation o verlays the video; as a r esult the vide o you see is darker than the actual video . T o hide the in formation dis play so that you can be tter see th e video, pr ess the "Inf o/Sele ct" button o n the IR remote.
Runni ng the S tanda lone Demos Runnin g the De monstrati on Softwa re 3-7 3.3.2 About the Encode + Decode Demo The Encode + Dec ode dem o allow s you to rec ord and pl ayback video. Video input comes f rom a sourc e, it is encode d, then deco ded, and sent to your video display .
Runni ng the S tanda lone Demos 3-8 Note that you c an use only a speech encode r , not an aud io enco der . Th e support ed video alg orithms are H.264 (.264 exten sion) and MPEG4 (.mpeg4 fi le extens ion). The supported spe ech algor ithm is G . 71 1 (.
