Video overlay using VAAPI

[Wolfgang Grandegger]

Hello,

I want to program a GStreamer pipeline overlaying a video generated with
"videotestsrc" over a video received from the network on an Intel PC
(VAAPI).  What is the most efficient way to realize such an overlay. The
overlay works fine with "clockoverlay" but I have not found yet a
solution with "videotestsrc".

Any help is appreciated.

Thanks,

Wolfgang.
