vapoursynth-zipcl
vszipcl is a VapourSynth plugin written in Zig that provides
OpenCL-accelerated video filters. Each filter is a faithful port of an established
reference, verified bit-exact where the reference allows, and shares one fast architecture
(a shared cl_context, a prewarmed per-stream resource pool, and a num_streams knob that
actually scales on the GPU).
All filters accept 8/16-bit integer, 16-bit half, and 32-bit float input and are
multi-plane (Gray / YUV / RGB, subsampled chroma). Every filter also takes device_id
and num_streams.
FILTERS
- Bilateral: OpenCL port of VapourSynth-BilateralGPU — bit-exact on integer input.
- Deband: OpenCL port of
placebo.Deband(libplacebo'spl_shader_deband). - EEDI3: Edge-directed interpolation (
EEDI3vertical,EEDI3Hhorizontal). - GaussBlur: Separable Gaussian blur.
- NLMeans: Non-local means denoiser, matching KNLMeansCL.
BENCHMARK
1080p YUV420, filter-bound, RTX 3070 Ti (num_streams=2). vszipcl leads every head-to-head, and
integer/half wire formats are often faster still (they move fewer bytes over PCIe). Full per-format
tables (u16/f16/f32 × num_streams 1 & 2) with methodology:
