<p>It's an intercept module that goes between the computer's video
output and the monitor's video input. It snoops on the stream of
video data going to the monitor, re-encodes it, and streams it
over its data output connection to a host computer. The host
doesn't need to be the computer that is generating the video data,
so in JF's situation he could record a high-quality video of the
Ventoy boot up process using a completely separate computer.</p>
<p>I think that the little iCan device might work, although since it
doesn't seem to have a video pass-through connector JF would have
to use the video data stream going to the computer doing the
recording as the "monitor", rather than an actual physical
monitor.<br>

That is, we're capturing output to HDMI "screen".

demonstrate Ventoy running while booting, unless I convert a
physical USB device to an ISO file and try (!) to use it
within a VM. But if I can capture the output from an external
device, I will be able to save it for future, but also for
live demo of about anything I want to show.
<br>
<br>
Any good or bad experiences with such devices under Linux ? I
did a quick Google search and it looks like there are several
devices, actually too many options to be able to properly
select.
<br>
<br>
<br>
My requirements are:
<br>
<br>
- Must run with Linux
<br>
- Need to be an external device
<br>
- Need to connect on USB 3
<br>
- Need an output port to connect to a monitor
<br>
<br>
Thanks :-)
