<p class="MsoNormal"> I've tried to fill the attribute as your example and the vaSurface can be created successfully. (format is NV12)<o:p></o:p></p>

</div>
<div>
<p class="MsoNormal"> I use ffmpeg with libva to decode H.264 frames on the vaSurface and call vaPutSurface() to show the surface on UI (refer to the sample in:
<a href="https://gitorious.org/hwdecode-demos/">https://gitorious.org/hwdecode-demos/</a>). The frames look incorrectly at the first 20 frames and the 21th and following frames become correct, so I do a small test: fill the cl_mem as "000...000" (make the
surface look green) before calling PutSuface(). Then, the first 20 frame indeed looks green as my expectation and the following frames become normal video content again. It looks like that they doesn't share memory anymore. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> Do I need to create the new surface whenever before decoding a frame? (I though just one surface created at the beginning and the frames decoded on the same surface.)<o:p></o:p></p>
