FFmpeg's common filter "v360" missing
26 septembre 2021, par Niklas E.I'm trying to convert a 180° fisheye video to a normal/regular video using the
v360
filter of FFmpeg.

This is the command I tried :

ffmpeg -i in.mp4 -vf "v360=input=fisheye:output=flat:iv_fov=180:v_fov=90" out.mp4


But the output says clearly
No such filter: 'v360'
, although v360 is a common filter listed in docs and other filters I used before worked just fine. I tried updating/reinstalling and looking for solutions, not fixing it.

Why is the filter missing ? How can I debug this ? Should I doe the task using another program entirely ?


Command output :

Init improvement : Don’t fail if Flash URL is null in normal include + init case. Instead, show note in debug input and wait for soundManager.setup() with url param, then treat as delayed init case. Improved experience if including , then trying to do setup() after DOM Ready (common jQuery case)
