The important question is what recipe are you using to get the vaapi elements?

What happens if you use vaapisink with AVI/3GP?  You should still get
some acceleration.

Note that especially when using vaapi sink you need to wait for the
sink to create the window and then reparent it, you can't provide your
own X window to vaapisink.  This is the usual cause for breakage.  Do
testing with gst-launch before attempting to use your own application.
