mpeg2 dxva decode issue

[jchen210]

Hi All,

I'm developing a mpeg2 DXVA decoder by D3D11 for DVD playback. the decoder mostly works well, but some disc have many titles, which need stop and play many times.

I have destroyed the decoder on stop, and create video decoder at the beginning of playback. sometimes crash occurs in video decoder submitting decoder buffer.

this is stack:
