<li><p>After restarting into the system, open a terminal on the desktop, and then run the '''test_hdmiin.sh''' script</p>

<li><p>Then you can see the input screen of the HDMI in (the HDMI in in the figure below shows the screen of the OPI5 development board HDMI output, and it is playing a video at this time). '''test_hdmiin.sh''' script defaults to the audio entered by HDMI in to the HDMI_TX1, HDMI_TX2 and ES8388 (representing speakers or headphones) of the development board.</p>

<li><p>In addition to testing HDMI IN using '''test_hdmiin.sh''', we can also use '''Qt V4L2 test Utility''' to test HDMI in video ('''<span style="color:#FF0000">this method cannot test audio at present</span>'''). The detailed steps are shown below：</p>
