Hi,

Can you provide more information about what you are doing to see this error?

Are you seeing the error when you use one of the samples with an elementary MPEG2 (video-only) media stream?

If you are using the Video Decoding Sample pleases describe the line that shows this error.  You should not see this error as return of MFXVideoDECODE_DecodeFrameAsync call.  It is error of other calls, and MFXVideoDECODE_DecodeFrameAsync can return other errors.

Hi,
I am using sample_decode_drm and i am getting this error as result of MFXVideoDECODE_DecodeFrameAsync. I am using vaapi hw accelerator and out_video_memery with external frameallocator. If i use internalframeallocator than everything is working.

Is there any debug symbols available for downloading to check what wrang?

I'll have to check on availability of symbols for Linux Servers.  if internal allocation works, but your external version does not, it may be a video memory allocation requirement that is not being met (width must be multiple of 16, etc.).
