commit c7546ce0ea6e451c33bf16c8ea1a341b917652a5 Author: Diego de Souza <[email protected]> AuthorDate: Sat Mar 14 01:11:31 2026 +0100 Commit: Timo Rothenpieler <[email protected]> CommitDate: Tue Jul 14 19:45:02 2026 +0000 avutil/pixfmt: add AV_PIX_FMT_CUARRAY for opaque CUDA block-linear surfaces Add a new hardware pixel format representing opaque block-linear CUDA arrays (CUarray). This format is used by NVDEC when decoding into opaque surfaces registered with cuvidRegisterDecodeSurfaces, and can be consumed directly by NVENC as CUDA array input without requiring a pitch-linear copy.
