This is on a Dragonboard 410c[1], using Linux 4.14.0 as provided by Linaro[2], using an up to date ALARM[3].

A short animation reproducing this bug is attached.

It displays a frame from the future about each half a second when using filesrc ! matroskademux ! v4l2vp8dec ! waylandsink.

Even with capture-io-mode=mmap (thus using wl_shm rather than linux_dmabuf for Wayland buffer upload), this still happens.

I can reproduce this with the following too:

ffplay -codec:video vp8_v4l2m2m https://bug797056.bugzilla-attachments.gnome.org/attachment.cgi?id=373507

Which indicates it's not just GStreamer.
