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.
