如题。
QSV硬解之后,放入qsv_scale输出的视频文件总是存在绿边。

I use QSV (Intel Quick Sync Video) decode the .mp4 video, then push it into QSV_scale filter(from 1280x720 to 1280x720) for testing the functions. As a result, the output video has a green line on the bottom.

I know there is piping aligning before decoding, and the frame we got after decoding is (AVframe :1280x720, hw_frame_ctx:1280x736,surface1->Info->height,weight:1280x736,surface1->Info->CropX,CropY:1280x736).

The filter output parameter is "qsv_scale:1280x720"

Could help me to check how to avoid this green line?
