Sharing Video and Audio between Machines

22.07.2022 - 23:05

Wanted to use laptop as second monitor for my main linux machine. Possible solutions:

Barrier.

Managed to get it working with some tinkering.

needed to create the file TrustedServers.txt on the client:

scp Local.txt dnbias@sky:TrustedServers.txt

For this to work the sshd on the client (dnbias@sky) must be running ofc.

Then, server:

barriers -f --no-tray --name ray --disable-client-cert-checking -c /home/dnbias/.config/barrier/barrier.conf --address 192.XXX.X.XX:24800

client:

barrierc -f --no-tray --name sky 192.XXX.X.XX:24800

x2vnc
x2go

For audio see this issue, using ffmpeg to stream audio from client to server. Basically:

ffmpeg -re -f pulse -ac 2 -i default -f rtp rtp://server:1234

server is the barrier server ip, pulse can be substitued by alsa. Copy the SDP output on a file on the server-side, then run the following to listen to the stream:

./ffplay -protocol_whitelist 'rtp,file,udp' .\sdp_file

Another alternative is to run

ssh -X desktop_hostname

from the slave/client, then you can run apps running on the server and displayed on the client.
