not implemented yet for the i.MX6? And why does drmModePageFlip() still
work with DRM_MODE_PAGE_FLIP_EVENT ?

I want to implement triple buffering instead of double buffering for a
program that uses EGL on GBM on a KMS-enabled platform. So far, I used
kmscube as an example.
However, I do not see where I can specify that I want to have 3 buffers
allocated instead of 2. From what I saw, I could try to c

Carlos, care to throw a comment why it's using nmem and not something

Hm, I do see a potential problem now. The code that maps/unmaps the
buffer and calls buf_to_fd() should also set nmems to 1. Then the

Strange ... for some reason, the prefix is wrong, and "kmscube" is
missing. Sorry about that. This set of 12 patches is to be applied
against kmscube.
Anyway, that's the last patchset version I'll post until it is merged
and/or reviewed.

With synced playback, frames may be dropped if the OpenGL ES code does
not output the decoded frames in time, thereby making sure the timestamps
in the video aren't missed

This is done by setting a max-lateness and enable QoS messaging. This
will have the effect that buffer arriving late to the appsink won't will
be dropped instead of being queued. This is similar to what GstVideoSink
base class would do.
