libVLC dewarp fisheye/2D non linear stretch

[RustyKnight]

I'm using libVLC (for iOS) in a project which connects to several IP based security cameras. One requirement which has come up is the desire to "dewarp" fisheye (180 degree) cameras.

I've tried making use of "updateViewpoint", but this seems related to 360 based video and has no obvious effect.

There's some discussions about around

Code: Select all

ffmpeg

supporting it using things like

Code: Select all

-vf v360=fisheye:equirect:id_fov=360

Code: Select all

-vf v360=fisheye:equirect:ih_fov=360:iv_fov=360

Code: Select all

-vf v360=dfisheye:e:yaw=-90

but I'm not aware of how this might be passed through "libVLC" or if it's even possible

As there any feature or means by which I might accomplish this? Most of the discussions around "dwarping" are based on 360 video which doesn't seem to be helping
