Hi,I have had only half-finished but working OpenCL filter version of v360 for ffmpeg/libavfilter.I need to recheck if I still have source code of vf_v360_opencl.c and related files/changes still somewhere.The Vulkan version never was really functional like OpenCL version is, and if you want Vulkan version better contact Vulkan expert(s) at FFmpeg.At least over IRC channel, #ffmpeg-devel on libera IRC servers, by IRC nick name Lynne.I'm not working on Vulkan stack so I do not have all necessary skills for very optimal filter implementation, moved to do other stuff instead.The old Vulkan WIP patch was here, which was then tested on old integrated Intel GPU:But Vulkan API is changing and FFmpeg related support code too, so it needs more work, and more other transforms needs to be implemented for other projections in v360 vulkan filter...RegardsOn Sat, Jan 24, 2026 at 12:07 PM Milos <milos@whitebox.aero> wrote:Hello Paul,I'm working on a project utilizing the ffmpeg's v360 filter and we're looking into ways to accelerate it. We found your messages on ffmpeg-devel's mailing list: https://ffmpeg.org/pipermail/ffmpeg-devel/2024-June/330229.html, and I was wondering if you'd be willing to share the patches for us to try them out.You can check the project out here: https://docs.whitebox.aeroIf that's alright, we'd like to try them out, and, considering your ffmpeg expertise, potentially contract you for some help getting it running / merged upstream if you'd be willing to help.Looking forward to hearing from you.Thanks!Milos
