Writing to frame buffer that appears as a v4L2 device in embedded linux



  • I am working on an embedded system that uses a custom display path in which we are considering a framebuffer driver that appears as a v4l2 device in the Linux filesystem. Is there a Qt platform backend/plugin that will work in this situation?

    Hi and welcome to devnet,

    Just learned that v4l2 also has the output concept. If I where to go from scratch I would take a look at the LinuxFB backend for the structure.
