Can you explain in more detail your use of libavdevice here?

My general sense is that while they might sometimes be convenient to use if you are already working in a libav* context, they are so limited (by both the API and the implementation) that most users who want video output to a screen will turn more full-featured players to implement this.

(To be clear here, I am talking specifically about outputs to a screen like fbdev/xv, not about output to non-screen-like devices such as v4l2 which certainly do have other use-cases.)

Thanks,
