Ah, I see. If I'm understanding you correctly, you are doing hardware
decoding in your filter, and you need to decode to a hardware surface.
Therefore, when the default video renderer switches to software
rendering and gives you a buffer in system memory, you can't decode to
that buffer. Does that sound right? Let me know if I'm on the right
track.
Yes, your redescription is very accurate!
This problem has troubled me for a long time. I have tried many methods, but
still cannot solve it.
Could you please kindly help this?

It sounds likeyou need to do that decoding in software.
