I am using ffmpeg 4.1.3 H264_qsv encoder to capture a video from camera at 1920 x 1080.
the camera outputs BGRA frame, and I use Intel IPP function ippiBGRToYCbCr420_8u_AC4P2R to convert it to NV12 format. then the NV12 frame is passed to H264_qsv encoder. the video file extension is mp4.
however, the video has a horizontal green bar at the bottom of video. the height of the bar is a few pixels and the width is across the full frame.
does anyone have some advices how to debug the problem?
thank you and regards
