The Scalable Video Technology for AV1 (SVT-AV1 Encoder and Decoder) with perceptual enhancements for psychovisually optimal AV1 encoding
An all-purpose AV1 video encoder designed for visually-optimal SDR and HDR image and video encoding.
Custom SVT-AV1 builds optimized for AMD Ryzen 9 7950X, 9950X & Threadripper (Zen 4 / Zen 5). Features AVX-512 hardware acceleration, HDR10+, and high-thread scalability for professional 4K/8K VFX, video editing, and encoding.
Video Encoder for Now and Next Decade
Slim FFmpeg 8.1 + dav1d xcframeworks for iOS, tvOS and macOS. Demux + decode + thin HLS-fMP4 mux for AVPlayer bridging. FLAC + EAC3 encoders for the audio bridge path. No network stack, no CLI binaries.
V4L2 stateless AV1 decoder for Rockchip RK3576 (VDPU383). Feature-complete and byte-identical to the vendor library on all programmable state; one open below-MMIO partial-decode bug fully triaged for the hardware owners.
