Dear all,

I have a question when learning ffmpeg qsv decoder and Intel media sdk.

The intel media sdk suggest to use Video Memory while doing Hardware decoding, use System Memory while doing Software decoding.

FFmpeg only used System Memory to decode with qsv (Intel msdk) in file libavcodec/qsvdec.c. Is there any problem when use Video Memory? 

Actually, I am trying to add Video Memory to FFmpeg qsv. But too many problems. Is there any one can give me some instruction?

Best Wishes,

Yuxiao Zhang
