Convert video to hequirect while setting the background black and blur the transitional area [closed]
11 février 2024, par ZurechtweiserI am using


ffmpeg -i input.mp4 -vf "v360=input=fisheye:ih_fov=122.6:iv_fov=94.4:output=hequirect:h_fov=180:v_fov=180:in_stereo=2d:out_stereo=sbs,format=yuv420p" -b:v 25M -maxrate 60M -bufsize 25M output.mp4



Which works as advertised to convert a fisheye to hequirect except for two problems :


- 

-
The background is not black but seems to try and set it to the average color of the video. It should be black throughout.


-
The corners are not blurred but should be, there should be a soft transition from the corner of the video into black.
