node-av Release v5.0.0

📦 Updated Packages

The following platform packages have been updated to v5.0.0:

Breaking Changes

Encoder/Decoder/FilterAPI/BitStreamFilterAPI - Send/Receive Pattern

The encode, decode, filter, and process methods now follow FFmpeg's send/receive pattern more closely. FFmpeg can produce multiple output frames/packets for a single input (e.g., B-frames in encoding, frame buffering in decoding).

Changes:

Methods now return void instead of a single Frame or Packet
You must call receive()/receiveSync() to retrieve output frames/packets
Supports proper multi-frame/packet output handling

Migration Example:

// Before
const frame = await decoder.decode(packet);
const packet = await encoder.encode(frame);

// After
await decoder.decode(packet);
const frame = await decoder.receive(); // May need to call multiple times

await encoder.encode(frame);
const packet = await encoder.receive(); // May return multiple packets

Added

Core Features

Fifo - Generic FIFO buffer bindings (AVFifo) for arbitrary data types
FilterComplexAPI - Support for complex filtergraphs with multiple inputs/outputs
- Advanced multi-input/multi-output filter operations
- Direct mapping to FFmpeg's filtergraph functionality
- Use cases: overlay, picture-in-picture, side-by-side, multi-stream mixing
WhisperTranscriber - High-level API for automatic speech recognition
- Based on OpenAI's Whisper model with whisper.cpp integration
- GPU acceleration support (Metal/Vulkan/OpenCL)
- Voice Activity Detection (VAD) for better audio segmentation
- Automatic model downloading from HuggingFace
- Multiple model sizes: tiny, base, small, medium, large
- Type-safe transcription segments with precise timestamps

Code Examples

FilterComplexAPI - Picture-in-Picture Effect:

import { FilterComplexAPI } from 'node-av/api';

using complex = FilterComplexAPI.create(
  '[1:v]scale=320:240[pip];[0:v][pip]overlay=x=W-w-10:y=H-h-10[out]',
  {
    inputs: [{ label: '0:v' }, { label: '1:v' }],
    outputs: [{ label: 'out' }],
  }
);

for await (using frame of complex.frames('out', {
  '0:v': decoder1.frames(input1.packets(streamIndex1)),
  '1:v': decoder2.frames(input2.packets(streamIndex2)),
})) {
  for await (using packet of encoder.packets(frame)) {
    await output.writePacket(packet, outputStreamIndex);
  }
}

WhisperTranscriber - Audio Transcription:

import { Demuxer, Decoder, WhisperTranscriber } from 'node-av/api';

using transcriber = await WhisperTranscriber.create({
  model: 'base.en',
  modelDir: './models',
  language: 'en',
  useGpu: true,
});

await using input = await Demuxer.open('podcast.mp3');
using decoder = await Decoder.create(input.audio());

for await (const segment of transcriber.transcribe(decoder.frames(input.packets()))) {
  const timestamp = `[${(segment.start / 1000).toFixed(1)}s - ${(segment.end / 1000).toFixed(1)}s]`;
  console.log(`${timestamp}: ${segment.text}`);

  // [0.0s - 5.2s]: Welcome to the podcast...
  // [5.2s - 10.8s]: Today we will discuss...
  // ...
}

Fixed

EOF Handling & Stability

Comprehensive improvements to end-of-file handling across the entire API stack, ensuring data integrity and preventing frame/packet loss during stream termination:

Decoder - Proper EOF propagation through decode/receive pipeline with complete buffer flushing
Encoder - Correct EOF handling in encode/receive pipeline guaranteeing all buffered packets output
FilterAPI - Consistent EOF processing through filter chains preventing dropped frames during flush
Demuxer - Reliable EOF detection and signaling for all stream types
Muxer - Proper finalization and trailer writing on EOF

General Improvements

node-av Release v4.0.0

📦 Updated Packages

The following platform packages have been updated to v4.0.0:

Major Focus: FFmpeg CLI Compatibility & Production Stability

This release brings the High-Level API closer to FFmpeg CLI behavior, making it more intuitive, stable, and robust for production use.

Breaking Changes

Class Renaming: The High-Level API classes have been renamed to better reflect their FFmpeg terminology:

MediaInput → Demuxer
MediaOutput → Muxer

High-Level API Refactoring: All High-Level API classes (Demuxer, Muxer, Decoder, Encoder, FilterAPI, BitStreamFilterAPI) have been refactored with improved type definitions, option handling, and significantly enhanced stability. Many aspects have been brought closer to FFmpeg CLI behavior, including automatic parameter propagation, metadata preservation, robust error handling, and better defaults. This makes the API more intuitive and production-ready.

Native Bindings Enhancement: Many additional useful utility functions have been added to the native bindings for improved low-level control and functionality.

Migration: Update your imports and class references. Review your High-Level API usage - some option property names/types may have changed. The Low-Level API remains stable.

Changed

FFmpeg Update: Updated to latest FFmpeg master version with newest features, performance improvements, and bug fixes

node-av Release v3.1.1

📦 Updated Packages

The following platform packages have been updated to v3.1.1:

Added

MediaInput: Custom I/O callbacks support via IOInputCallbacks

import { MediaInput } from 'node-av/api';

import type { IOInputCallbacks } from 'node-av/api';

const callbacks: IOInputCallbacks = {
  read: (size: number) => {
    // Read data from custom source
    return buffer; // or null for EOF
  },
  seek: (offset: bigint, whence: AVSeekWhence) => {
    // Seek in custom source
    return offset;
  }
};

await using input = await MediaInput.open(callbacks, {
  format: 'mp4',
  bufferSize: 8192
});

MediaInput: Buffer input support in synchronous mode
- MediaInput.openSync() now accepts Buffer input
- Previously restricted due to callback requirements
- Enabled by direct callback invocation improvements

Fixed

Critical: Fixed deadlock when using using keyword with IOOutputCallbacks
- MediaOutput with custom I/O callbacks now properly closes synchronously
- Direct callback invocation in same thread eliminates event loop dependency

// This now works without deadlock!
try {
  using output = MediaOutput.openSync(callbacks, { format: 'mp4' });
  // ... write packets
  // Automatically closes without deadlock
} catch (e) {
  console.error('Error caught correctly!', e); // ✅ Works now
}
