Dma-buf local display

[Charles Frey]

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.
