how does clutter-gst/totem work with dmabuf buffers from v4l2 decoders?

[HalleyZhao]

Hi experts:

I notice that totem uses clutter-gst as videosink, then I look into clutter-gst (https://github.com/GNOME/clutter-gst).

however, I haven't found how it work with hardware accelerated decoder (usually generate dma_buf buffer for a video frame).

anyone can give some hints? thanks.

vaapi buffer can be mapped by the GstVideoMeta->map function.
