You'd better try it on Intel sandy bridge or ivy bridge first, it should work 
for multiple streams. And the driver code is also open sourced.

After validated your software work, you can turn back to GMA500 if you like.

Subject: [Libva] Decoding and displaying multiple streams using gstreamer-vaapi


Hi!

We're currently in the process of developing a player that should play back 
multiple incoming streams in a split screen scenario. We plan to use gstreamer 
and gstreamer-vaapi. We're using the latest EMGD-driver from Intel with a US15W 
(GMA500) graphics chipset.

We've done some initial tests and have encountered various problems with video 
surfaces starving each other. I.e. one shows video for a breif moment while the 
other is green and vice versa, flickering back and forth.

For this setup, what are you recommendations on how to implement it? Any common 
pitfalls regarding threading and the libva backend? How would gstvideocontext 
relate to all this? Is it possible at all?

Kind regards, Andreas Larsson
