ffmpeg's v360 hardware filters

Hey, I've asked Paul about the `v360` hardware-accelerated FFmpeg filters, thread below. He referred me to Lynne @ #ffmpeg-devel on Libera, to ask about the possible Vulkan implementation. I'll get in touch soon and update ============ Forwarded message ============ From: Paul B Mahol < mailto:onemda@gmail.com > To: "Milos"< mailto:milos@whitebox.aero > Cc: "xavier"< mailto:xavier@whitebox.aero > Date: Sat, 24 Jan 2026 13:51:52 +0100 Subject: Re: ffmpeg's v360 hardware filters ============ Forwarded message ============ 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: https://ffmpeg.org/pipermail/ffmpeg-devel/2020-June/265057.html 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...

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.aero If 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

Medical Leave - Surgery (Feb 27-Mar 02)

Hey, Apologies for missing yesterday’s review & update. This came up suddenly, and I had to arrange mediclaim and related formalities. I’ve been dealing with some ENT issues over the past few years, and after prolonged medication, surgery was advised. I’m scheduled for a septoplasty along with bilateral middle meatal antrostomy and related sinus procedures. Because of this, I’ll be hospitalised tomorrow (27th Feb), surgery will take place the following day, and I’ll remain under supervision for a few days to ensure everything is stable. I should be home by Sunday or Monday. This unfortunately means I’ll be down for the remainder of this sprint (vacation yay 😅!), but I’ll be around for the rest of alpha3 now that I've utilised a vacation week. Sorry for not discussing this during sprint planning & retro last Tuesday, I only found out myself the day after. I’ll update once I’m back and fully operational. :) Thanks, Avinash S.

Hi Milos, So did you get to reply to Paul, and test his code? Then if you get stuck, we can offer to him to help us test it, and sponsor finishing the work? -- Xavier On Mon, Feb 16, 2026, at 16:04, Xavier Antoviaque wrote: > That was because posts from non-members require manual approval.
