QSV on FFMPEG can not decode 1080p h264 stream?

Hi,

I get FFMPEG's qsvdec.c from version ffmpeg-20180130-42323c3-win64-dev. then make and build my own solution to decode h264 stream on Win10 & VS2015 through qsv feature. however, if input 1080p h264 stream, and it meets errors after decode some frames  and output log as:

[AVHWFramesContext @ 0000026ad0cf0820] Error synchronizing the operation:-17

Error thansferring the data to system memory.

On the other side, I input a 720*576 h264 stream to qsvdec, and it works well.

It's appreciate to anyone give me some advice.

Thanks & Regards.
