`crates/roboflow-dataset/src/lerobot/writer/encoding.rs:100-294` + +**Problem**: Video encoding happens **after** all frames are buffered. For a 10K frame episode: +- Memory: ~27GB (3 cameras × 640×480×3 × 10000 frames) +- Encode time: ~270 seconds at 100 MB/s for 27GB of raw data + +**Current Flow**: +```rust +// 1.

Then encode all at once (line 72-78) +encode_videos_sequential(camera_data, ...) +``` + +**Issues**: +- `images.clone()` creates full copy of all image data +- Sequential encoding per camera (no parallelism without hardware acceleration) +- PPM format adds overhead (header per frame) + +#### 2. **Memory Copy Chain** + +``` +S3/OSS → decode to arena → clone to ImageData → buffer in HashMap + │ + ▼ + PPM conversion (another copy) + │ + ▼ + FFmpeg stdin (yet another copy) +``` + +**Each 640×480 RGB frame**: 921,600 bytes +- Arena allocation: 1× +- HashMap storage: 2× +- VideoFrameBuffer: 3× +- PPM encoding: 4× (with headers) +- **Total: ~4× memory amplification** + +#### 3. **FFmpeg Process Spawning Overhead** + +**Location**: `crates/roboflow-dataset/src/common/video.rs:267-510` +

.spawn() + .map_err(|_| VideoEncoderError::FfmpegNotFound)?; +``` + +**Overhead**: ~50-100ms per spawn × 3 cameras × 10 chunks = 15-30 seconds overhead + +#### 4. **Suboptimal Pixel Format Pipeline** + +**Current**: RGB → PPM → FFmpeg → H.264/yuv420p + +``` +ImageData (RGB8) → PPM header + RGB → FFmpeg stdin → libx264 → yuv420p → MP4 + │ │ │ + ▼ ▼ ▼ + 3 bytes/pixel 3+ bytes/pixel RGB→YUV

+**Check**: `crates/roboflow-dataset/src/lerobot/video_profiles.rs` + +--- + +## Optimization Proposal + +### Phase 1: Zero-Copy Pipeline (Immediate Win) + +#### 1.1 Direct NV12/NV21 Encoding (Eliminate RGB→YUV conversion) + +**Approach**: Keep images in compressed format (JPEG) or decode directly to NV12 + +```rust +// New ImageData variant supporting zero-copy +pub enum ImageData { + Rgb8(Vec), // Current: RGB8 raw + Jpeg(Arc>), // NEW: JPEG passthrough + Nv12(Arc>), // NEW: Direct YUV + Compressed { // NEW: Codec-aware storage + codec: ImageCodec, + data: Arc>, + width: u32, + height: u32, + }, +} +``` + +**Benefit**: +- Skip RGB→YUV conversion in FFmpeg +- Use `-c:v h264_nvenc -rc -b:v 0` (lossless/pass-through) +- **3-5x faster encoding** + +#### 1.2 Shared Ownership (Eliminate Cloning) + +**Current**: +```rust +.map(|(camera, images)| (camera.clone(), images.clone())) // FULL COPY +``` + +**Proposed**: +```rust +pub struct FrameBuffer { + images: HashMap>, // Arc instead of owned +} + +// No clone needed when encoding +encoder.encode_buffer(&image_data, path) // Pass Arc directly +``` + +**Benefit**: 2× memory reduction + +#### 1.3 Persistent FFmpeg Process (Eliminate Spawn Overhead) + +**Current**: Spawn per camera per chunk + +**Proposed**: Spawn once per camera, stream frames + +```rust +struct PersistentEncoder { + ffmpeg_process: Child, + stdin: BufWriter, + camera: String, + episode_index: usize, +} + +impl PersistentEncoder { + fn add_frame(&mut self, frame: &VideoFrame) -> Result<()> { + // Write directly to running process +

Overview - -### Problem Statement - -Robotics teams generate large volumes of recording data (bag/MCAP files) that need to be converted to ML-ready dataset formats for training. Manual conversion is: -- **Slow**: Sequential processing cannot keep up with data generation -- **Error-prone**: No coordination means duplicate work or missed files -- **Resource-intensive**: Video encoding is CPU/GPU heavy - -### Solution - -A distributed pipeline that: -1. **Discovers** new files in S3/OSS automatically -2. **Distributes** work across GPU-enabled workers -3. **Converts** to LeRobot v2.1 (and other formats) with GPU acceleration -4. **Tracks** progress with exactly-once semantics -

- Extensible to KPS, custom formats - -3. **Operations** - - Automatic file discovery - - Distributed job coordination - - Progress tracking and resume - - Duplicate detection - -### Non-Functional Requirements - -1. **Throughput**: 10 Gbps sustained -2. **Availability**: 99.9% (worker failures handled automatically) -3. **Consistency**: Exactly-once processing semantics -4. **Scalability**: Linear scaling with worker count -

process_job() method. Wire up: - - Storage backend for input/output - - LerobotConfig from job parameters - - Episode finalization and upload - ``` - -2. **[Phase 1.4] Wire up checkpoint save/restore in pipeline** - ``` - Complete the checkpoint integration: - - Save checkpoints periodically during processing - - Restore from checkpoint on job resume - - Delete checkpoint on successful completion - ``` - -3. **[Phase 2.1] Implement PrefetchQueue with 2 slots** - ``` - Create a prefetch pipeline that downloads the next job while - the current job is being processed: - - PrefetchQueue with configurable slot count - - Background download task - - Memory-mapped file handling for large downloads - ``` - -4. **[Phase 4.4] Load testing at 10 Gbps** - ``` - Create load testing infrastructure: - - Synthetic workload generator - - Throughput measurement tooling - - Bottleneck identification - ``` -
