I tried to use TI latest edgeai image for TDA4VM, it has some gst-plugin inside the image(although this image disabled weston, but it still works using kmssink instead of waylandsink) , test some commands from TI wiki and GitHub page, but still doesn't works as attached failed log. So I think the major problem is I don't know how to change the virtual channel number using gstreamming.
I'll appreciate if someone can give me directions, thanks a lot
