how to display in /dev/fb1


I have two display now.

using NvEglRenderer, default display in /dev/fb0

but how to display in /dev/fb1

Please share how you connect to two displays. We have one hdmi port on default board and it can be connected to one display. You might have some other hardware device to connect the second display. We will need the information so that we can suggest next.


one display connection(/dev/fb0): tx2–dsi–dsi2hdmi–hdmi – monitor1
another display connection(/dev/fb1): tx2–hdmi – monitor2

using NvEglRenderer,app default display in monitor1.
I want it show in monitor2 default.

thanks for reply!

NvEglRenderer does not support this case. It only outputs to fb0. Would like to suggest you try nvoverlaysink plugin in gstreamer. you can configure the property:

> display-id          : Display on which overlay should be rendered
                        flags: readable, writable
                        Unsigned Integer. Range: 0 - 4294967295 Default: 0
