{| class="wikitable" style="width:800px;" |-|<p>[orangepi@orangepi ~]$ '''test_hdmiin.sh'''</p>|}</li>
<li><p>Then you can see the input screen of HDMI In (the HDMI In in the figure below shows the HDMI output screen of the opi5 development board, and a video is being played at this time). The '''test_hdmiin.sh''' script will play the audio input from HDMI In to HDMI_TX1, HDMI_TX2 and ES8388 (representing speakers or headphones) of the development board by default.</p>
