Adding Vulkan presets to Intel oneVPL
by Terje J. Hanssen 02 Dec '25

02 Dec '25

Late 2024 onevpl support was added for the buildsystem with various presets using cin_hw_dev=vaapi. Maybe I simplify too much, but is it possible that current CinGG-20251121-x86_64.AppImage with ffmpeg-8 is ready to test vulkan the same way, just by replacing "vaapi" with "vulkan" in the presets? hevc_vaapi_8b420.mp4 mp4 hevc_vaapi cin_hw_dev=vaapi cin_pix_fmt=nv12 profile=main # global_quality=22 hevc_vaapi_10b420.mp4 mp4 hevc_vaapi cin_hw_dev=vaapi cin_pix_fmt=p010le profile=main10 # global_quality=22 hevc_vaapi_10b422.mp4 mp4 hevc_vaapi cin_hw_dev=vaapi cin_pix_fmt=y210le profile=rext # global_quality=22 Terje J.

Add vulkan detection to configure.ac
by Andrew Randrianasulu 02 Dec '25

02 Dec '25

Should make enabling it easier ? defaults to "no", should be enabled by passing --with-vaulkan to out configure. I plan to add similar blocks for libzimg and libplacebo.

FFmpeg 8.0 in CinGG
by Andrea paz 01 Dec '25

01 Dec '25

I see that ffmpeg 8.0 has three new filters: Color Detect, Pad_Cuda, and Scale_d3d11. In CinGG, I only see the first one, Color Detect, which provides information on the “Jpeg/Mpeg” range and whether the alpha channel is ‘premultiplied’ or “straight.” It doesn't give me any errors, but I don't know where to see the information it provides. FFmpeg 8.0 also has other good news: decoders for the APV mezzanine codec (very interesting!) and for ProRes RAW. Improved VVC support (this would be h266, the successor to h265). Then encoding/decoding via Vulkan of FFV1 and ProRes Raw (for this only decoding). Still decoding Vulkan VP9, Vaapi VVC; ProRes and VC-2. I don't know if Vulkan AV1; ProRes and VC-2 encoding is already supported or coming soon. I don't know enough about other new features (G.728; Whip, etc.).
