From 47744e375f79d1f313ca0b4622add284cd605031 Mon Sep 17 00:00:00 2001 From: StreamKit Devin Date: Thu, 9 Apr 2026 13:05:50 +0000 Subject: [PATCH 01/23] feat(nodes): add HW video codec backends (Vulkan Video H.264, VA-API AV1, NVENC/NVDEC AV1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement hardware-accelerated video encoding and decoding for StreamKit, targeting Linux with Intel and NVIDIA GPUs (issue #217). Three backends behind optional feature flags: vulkan_video — H.264 encode/decode via Vulkan Video (vk-video v0.3). Cross-vendor (Intel ANV, NVIDIA, AMD RADV). Includes lazy encoder creation on first frame for resolution detection, NV12/I420 input support, and configurable bitrate/framerate/keyframe interval. vaapi — AV1 encode/decode via VA-API (cros-codecs v0.0.6). Primarily Intel (intel-media-driver), also AMD. Uses GBM surfaces for zero-copy VA-API buffer management. Includes stride-aware NV12 plane read/write helpers with odd-width correctness. nvcodec — AV1 encode/decode via NVENC/NVDEC (shiguredo_nvcodec v2025.2). NVIDIA only (RTX 30xx+ decode, RTX 40xx+ AV1 encode). Dynamic CUDA loading — no build-time CUDA Toolkit required for the host binary. All backends share: - HwAccelMode enum (auto/force_hw/force_cpu) for graceful fallback - ProcessorNode trait integration with health reporting - Consistent config structs with serde deny_unknown_fields validation - Comprehensive unit tests (mock-based, no GPU required) Closes #217 Signed-off-by: Devin AI Co-Authored-By: Claudio Costa --- Cargo.lock | 552 +++++++- crates/nodes/Cargo.toml | 14 + crates/nodes/src/video/mod.rs | 43 +- crates/nodes/src/video/nv_av1.rs | 1184 ++++++++++++++++ crates/nodes/src/video/vaapi_av1.rs | 1807 ++++++++++++++++++++++++ crates/nodes/src/video/vulkan_video.rs | 1461 +++++++++++++++++++ justfile | 3 +- 7 files changed, 4998 insertions(+), 66 deletions(-) create mode 100644 crates/nodes/src/video/nv_av1.rs create mode 100644 crates/nodes/src/video/vaapi_av1.rs create mode 100644 crates/nodes/src/video/vulkan_video.rs diff --git a/Cargo.lock b/Cargo.lock index 800ab5c8..5390b6dc 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -174,7 +174,7 @@ checksum = "0ae92a5119aa49cdbcf6b9f893fe4e1d98b04ccbf82ee0584ad948a44a734dea" dependencies = [ "proc-macro2", "quote", -

Uses the [`shiguredo_nvcodec`](https://crates.io/crates/shiguredo_nvcodec) +//! crate which provides Rust bindings for the NVIDIA Video Codec SDK. CUDA +//! driver API is loaded dynamically at runtime (`dlopen`) — no build-time +//! CUDA Toolkit dependency. +//! +//! This module provides: +//! - `NvAv1DecoderNode` — decodes AV1 packets to NV12 `VideoFrame`s via NVDEC +//! - `NvAv1EncoderNode` — encodes NV12 `VideoFrame`s to AV1 packets via NVENC +//! +//! Both nodes perform runtime capability detection: if no NVIDIA GPU with +//! AV1 support is found, node creation returns an error so the pipeline can +//! fall back to a CPU codec (rav1e/dav1d/SVT-AV1). +//! +//! # Feature gate +//! +//! Requires `nvcodec` feature. +//! +//! # GPU requirements +//! +//! - **AV1 decode**: NVIDIA RTX 30xx (Ampere) or newer. +//! - **AV1 encode**: NVIDIA RTX 40xx (Ada Lovelace) or newer. + +use async_trait::async_trait; +use bytes::Bytes; +use opentelemetry::global; +use schemars::JsonSchema; +use serde::{Deserialize, Serialize}; +use std::borrow::Cow; +use std::sync::Arc; +use std::time::Instant; +use streamkit_core::stats::NodeStatsTracker; +use streamkit_core::types::{ + EncodedVideoFormat, Packet, PacketMetadata, PacketType, PixelFormat, RawVideoFormat, + VideoCodec, VideoFrame, VideoLayout, +}; +use streamkit_core::{ + config_helpers, get_codec_channel_capacity, packet_helpers, state_helpers, InputPin, + NodeContext, NodeRegistry, OutputPin, PinCardinality, PooledVideoData, ProcessorNode, + StreamKitError, VideoFramePool, +}; +use tokio::sync::mpsc; + +use super::encoder_trait::{self, EncodedPacket, EncoderNodeRunner, StandardVideoEncoder}; +use super::HwAccelMode; +use super::AV1_CONTENT_TYPE; + +// --------------------------------------------------------------------------- +// Decoder +// --------------------------------------------------------------------------- + +/// Configuration for the NVIDIA AV1 decoder node. +#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)] +#[serde(default, deny_unknown_fields)] +pub struct NvAv1DecoderConfig { + /// Hardware acceleration mode. + pub hw_accel: HwAccelMode, + /// CUDA device index (0-based).

The cros-codecs GBM allocator uses GBM_BO_USE_HW_VIDEO_ENCODER, a flag that Mesa's iris driver does not support for NV12 on some hardware (e.g. Intel Tiger Lake with Mesa 23.x), causing 'Error allocating contiguous buffer' failures. By using libva Surface<()> handles instead: - Surfaces are created via vaCreateSurfaces (no GBM needed) - NV12 data is uploaded via the VA Image API (vaCreateImage + vaPutImage) - The encoder's import_picture passthrough accepts Surface<()> directly - Pitches/offsets come from the VA driver's VAImage, not GBM This also adds two new shared helpers in vaapi_av1.rs: - open_va_display(): opens VA display without GBM device - write_nv12_to_va_surface(): uploads NV12/I420 frame data to a VA surface using the Image API, returning driver pitches/offsets Signed-off-by: StreamKit Devin Co-Authored-By: Claudio Costa --- Cargo.toml | 1 + crates/nodes/src/video/vaapi_av1.rs | 186 +++++++++++++++++++++------ crates/nodes/src/video/vaapi_h264.rs | 79 ++++++------ 3 files changed, 183 insertions(+), 83 deletions(-) diff --git a/Cargo.toml b/Cargo.toml index 96863e78..ffd8745b 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -78,6 +78,7 @@ opt-level = 3 [profile.dev.package.maybe-rayon] opt-level = 3 + [workspace.lints.rust] unsafe_code = "forbid" # missing_debug_implementations = "warn" diff --git a/crates/nodes/src/video/vaapi_av1.rs b/crates/nodes/src/video/vaapi_av1.rs index f69af6e9..771d17cd 100644 --- a/crates/nodes/src/video/vaapi_av1.rs +++ b/crates/nodes/src/video/vaapi_av1.rs @@ -163,6 +163,118 @@ pub(super) fn open_va_and_gbm( Ok((display, gbm, path)) } +/// Open a VA display without a GBM device. +/// +/// Used by encoder paths that pass VA surfaces directly to the encoder, +/// bypassing GBM buffer allocation entirely.

From 1d08b2c4bcea0c9765fbcdd5bf69d8e5b3c4322a Mon Sep 17 00:00:00 2001 From: StreamKit Devin Date: Fri, 10 Apr 2026 11:58:18 +0000 Subject: [PATCH 23/23] fix(nodes): use actual DMA frame layout for VA-API encoder metadata The VA-API AV1 and H.264 encoders were constructing CrosFrameMetadata with hardcoded UV plane offsets (y_stride * coded_height) and buffer_index 0 for all planes. These assumptions can be wrong on drivers that add inter-plane padding or use separate buffer objects per plane. Change upload_nv12_via_gbm() and upload_nv12_to_dma_frame() to return the actual FrameLayout (with real offsets, strides, and buffer indices from the PRIME descriptor / GBM allocator) instead of just pitches. Both VA-API encoders now pass this layout directly to cros-codecs, ensuring the metadata matches the DMA frame's actual memory layout.
