qsv dec meets error while get raw data from hw surface

Post by wharyoung » Fri Mar 02, 2018 8:08 am

hi, i use qsvdec.c and meet an error.
[img][C:\Users\denghuayang\Desktop\tmp\20180302160354.png]

it said " [AVHWFramesContext]@ 000001b842da7e40 Error synchronnizing the operation -17." after I called av_hwframe_transfer_data(sw_frame, frame, 0).
anyone can help me?

by the way, qsvdec works well while decoding 720x576 resolusion h264 stream.
but that error always appears when decoding 1080p h264 stream.
