    mpeg2 dxva decode issue

    julischeng

      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:
