Thank you so much Antoine and Benjamin for those ideas, I'll try to get
this running.
I also saw that it's possible to open the Gemwwin on a remote host with
the [remotehost( message to [gemwin] (see gemwin-help)
However, there is no further explanation of that feature and I haven't
seen any discussion on pd-list or here about it.
I was wondering if that could work too. With an X Server running on the
Android.

Or am I missing something?

Hi,
I was thinking about a solution to stream Gem output to network device
for a while
And the solution that came up to my mind is to render in a frame buffer
and send the texture to a GPU video encoder like nvenc then download
the encoded frame to the RAM and stream it.
This would be much more efficient than direct screen grabbing.
Unfortunately I didn't take the time to implement this for now.
Some vnc server use hardware compression but I don't know one on Linux.

I would say (if you are on linux) : use
https://github.com/umlaeute/v4l2loopback
<https://github.com/umlaeute/v4l2loopback> to create a virtual v4l2
device, then it's possible to use pix_record eventually in conjonction
with pix_snap to shoot Gem window and write it to this virtual v4l2
device (on my computer, it would involve to send a [codec v4l2< message
to pix_record)
then you can stream to the Android device with ffmpeg fed by this v4l2
device and read it with vlc
also possible to grab the Gem screen with ffmpeg -f x11grab +options
