After some time trying with drmModeAddFB2WithModifiers() I still can't display dmabufs on my screen, the error code is the same.
I double checked arguments to no avail and tried displaying dumb buffers created with drmIoctl and have no problem doing so.
Maybe is there something I missed ? Shouldn't I be able to create the framebuffers without specifying a fourcc code ?

You need to use “drmModeAddFB2WithModifiers()” instead of “drmModeAddFB()” in case your framebuffer needs to use fourcc codes as pixel format specifiers.
Thanks.
