Using both the normal vcall and the vcall advance, it is not possible to assign the camera connected to the smartphone via hdmi grabber as a video source,
but I only hear the audio.
can someone help me ?

With other applications it works perfectly.

Can you please explain in more detail what you connected where and what exactly isn't working or what you would expect. Thanks.

If you're talking about using an OTG USB adaptor to get a HDMI to USB capture working on your phone, AFAIK I'm not sure it can work with WebRTC in a browser.
Some specific apps, like Larix Broadcaster, support this but it is not available to Android by default.

as you can see in the picture I connected a usb grabber hdmi (usb 3.0) to the phone.
The input source is therefore hdmi.
Going on the vmix call instead does not see me the usb grabber.
or rather it is detected as an audio device (see photo).

But it is not revealed as a video source.
(see photo below).

Both Audio and Video are detected by other applications.

As I already explained, this would require the browser to check for external video sources declared at the system level. However HDMI grabbers are NOT declared at the system level. This is why only specific apps can use this feature.

OK thanks
however it would be nice if vmix call in a future update would be able to detect these sources.

vMixCall does not "detect" anything. vMixCall uses the devices which are available to the system.
