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. https://f-droid.org/repository/browse/?fdfilter=x%20server&fdid=au.com.d...
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 ++ b > > > M. > > > >> On 2017년 04월 01일 23:31, Alan Brooker wrote: >>> Hey Max, >>> >>> Recently I have been looking at this very subject, in the end using >>> trinus vr (trinusvirtualreality.com <http://trinusvirtualreality.com> <http://trinusvirtualreality.com <http://trinusvirtualreality.com>>) >>> on windows was the easiest solution for me >>> >>> I have tried something similar on linux (Fedora) but my problem was >>> just getting my PC to actually connect with my phone- this would be >>> trivial I assume for someone who is experienced setting up VNC >>> connections/networking on Linux.
