I am using FFMpeg and libva for getting hardware acceleration for my h.264 videos. With one H.264 stream everything is fine, but with two parallel H.264<br>
stream videos I am having a problem. I am creating two FFMpeg contexts (AVCodecContext, AVFormatContext etc) and two vaapi context but I am having<br>
problem with that. The errors that come are:<br>
<br>
VdpOutputSurfaceCreate(): status 25: A catch-all error, used when no other error code applies.<br>
<br>
vdpau_video: VdpPresentationQueueBlockUntilSurfaceIdle(): status 3: An invalid handle value was provided.<br>

Please provide a self-contained testcase. It's hard to tell otherwise since the NVIDIA driver would return this kind of error when none other fits.<div><br>

Also is there any way before we can know whether these error will come or not, actual decoding the frame (i.e. before calling avcodec_decode_video2 or<br>
calling vaPutSurface)<br>

<br></div>
VdpPresentationQueueBlockUntilSurfaceIdle() is used for vaPutSurface() implementation. If you use 0.7.x series, could you please also check whether prefixing your application with VDPAU_VIDEO_PUTSURFACE_FAST=0 makes a difference or not?<br>
