Maybe your TV can play video from a URL? Maybe from an RTSP
stream?
In which case something like this:
ffmpeg -video_size whateverxwhatever -framerate 30 -f x11grab -i :0 -f mpegts - \
| vlc -I dummy - --sout='#std{access=http,mux=ts,dst=:8554}
might be what you want, producing http://yourmachinesip:8554 as
an RTSP video source.
Format would likely need to be adjusted, I have not tried this.
I have been told that WebOS tvs usually support miracast, in
which case:
https://github.com/albfan/miraclecast
and
https://01.org/wds
might be useful to you.
