Hello friends,
I am continuously recording a video with audio from an ip camera using
ffmpeg.
I am getting a distorted video when I get in to the picture. If the
background is still, the video looks normal, but as soon as I step in to
the picture, I see myself only being distorted while the background stays
intact. If anyone went through this issue, I would really appreciate your
help. Here is a command that I am using:
ffmpeg -i rtsp://admin:admin@192.168.1.9/mpeg4 -map 0 -c:v libx264
-c:a aac -pix_fmt yuv420p -f segment -segment_time 60 -segment_wrap 10
-reset_timestamps 1 %d.mp4
This is a ffmpeg command output:
