Hi, working on embedded linux. I started two application instances each outputs to different frame buffers. system(”/opt/dvr_rdk/ti810x/bin/myapplication1 -qws hdmi0 hdmi1 -display LinuxFb:/dev/fb0 &”); system(”/opt/dvr_rdk/ti810x/bin/myapplication2 -qws hdmi0 hdmi1 -display LinuxFb:/dev/fb2 &”); /dev/fb0 corresponds to HDMI and /dev/fb2 corresponds to composite out. The mouse control is default to /dev/fb0. How could I switch the mouse control between these two applications ? Regards, Boby.
