D3D11 decoding requires that output is an array texture with a size fixed in advance. It sounds like you have not told the decoder that you are going to hold on to multiple frames in the output, so it has made the array texture too small. You probably want to set AVCodecContext.extra_hw_frames to tell the decoder how many frames you are going to hold on to.
