[FFmpeg-user] Hi, I want to ask a question about ffmpeg using dxva2 with multithreads

[高伟]

Hi,

I'm studying ffmpeg.I have added dxva2 to ffmpeg.exe,and it can work well
in one thread using dxva2 to decode h264

cmd :ffmpeg -threads 1 -i  XXXh264.mkv output.avi

But I added some codes to use dxva2 in multithread,it didn't work.

I want to ask is ffmpeg support dxva2 in multithreads?

I have no idea on how to do it.

Thanks
