Update: We're in touch with GitHub, Blacksmith and Namespace!

Timo is supporting ESA Marathon this weekend.

With 3 cloud offers, we're reassessing our needs. Still interested in non-x86, non-ARM solutions.

We're a little overwhelmed by all the offers, thank you so much!

[FFmpeg @FFmpeg]

Could you or your company sponsor an x86-64 server and hosting for FFmpeg’s CI?

RISC-V, PowerPC or MIPS systems would also be welcome! We currently test these using QEMU on our Ampere ARM server.

Please get in touch!

[FFmpeg @FFmpeg]

Thanks for the generous FFmpeg CI offers! We're in touch with several of you and aim to accept at least one cloud and one server offer, plus non-x86 hardware for native testing.

Nothing is finalized yet. If you've offered help, please check your DMs or message us!
