Dose anyone know who is responsible for the fate website? I can offer a server to do the fate test on loongarch, But I don’t know how to make it work for FFmpeg fate website. > 2021年11月2日 下午8:51，殷时友 写道： > > Hello > > I am trying to add support for loongarch(a new architect

[FFmpeg-devel] Support for loongson loongarch.

Hello I am trying to add support for loongarch(a new architecture launched by Loongson) in ffmpeg, Should I donate a test machine or just offer a qemu before uploading patches? Alos, who should I contact if I want to add loongarch state into fate.ffmpeg.org . Any other
