how does gstreamer select the default framebuffer?

Question

I am using gts-play-1.0 on Linux-iMx6 using following command:

gst-launch-1.0 playbin uri=file:/home/straw.mp4

the command selects /dev/fb0 and plays without any issues. But I want it to use the /dev/fb3 instead.

So does Gstreamer have the scope to config the framebuffer?

Answer 1

Check gst-inspect-1.0 fbdevsink for the element's options. I would pick device:

  device              : The framebuffer device eg: /dev/fb0
                        flags: readable, writable
                        String. Default: null

So with gst-play-1.0 you probably need to do something like gst-play-1.0 --videosink "fbdevsink device=/dev/fb3" video_file.mp4.
