This release fixes several issues found in the previous version (0.0.1a2), focused mainly on the Opus playback engine, metadata parsing and packaging. + +### ✅ What's Fixed in This Release + +**Opus playback engine (`opusplayer.py`)** + +- **Fade worker indentation** — `_fade_worker` was accidentally defined outside the `OpusAudio` class, causing `AttributeError` on `fadeout/fadein/fadein_pos`. It is now a proper class method. +- **Fade-in now stops and restarts** — `fadein_music` previously refused to run while playing ("Already playing"). It now stops any current playback first, starts a fresh AID, then fades in. +- **Seek now truly jumps** — `seek_audio` previously only moved the stream position without resetting the buffered audio, so jumps were not audible. It now restarts the playback thread from the new position. +- **Seek resumes after fade-out** — seeking now always restarts playback, even after a fade-out had stopped it. +- **Fade-out restores volume** — the volume was being reset to 0 after fade-out, making any later play/seek/fade-in silent. The normal volume is now restored after fade-out. +- **Boundary robustness** — `fadein_music(ms=None)`, `fadeout_music(None)` and `fadein_music_pos(position=None)` no longer crash with a TypeError; invalid values fall back safely to defaults or return an error tuple. + +**Opus metadata parsing (`audio_parser.py`)** + +- `open_audio(.opus)` no longer raises `ValueError`. A new `OPUSFile` parser delegates to `opusplayer`, so `get_audio_duration`, `get_audio_metadata` and `batch_get_metadata` all support Opus files. +- Directory scanning for `batch_get_metadata` now includes `.opus`. + +**Audio library routing (`player.py`)** + +- `get_audio_metadata_by_aid()` now routes Opus AIDs to the `OpusAudio` engine, returning consistent metadata. + +**Packaging** + +- Restored the main `ap_ds/__init__.py` (its exported functions had been accidentally replaced, which omitted all top-level APIs from the built package). All public APIs are exported again. + +**Tests** + +- CI/CD fade duration increased to 5s for a clearer audible effect. +- Added `test_opus_interactive.py` for manual Opus playback / seek / fade verification. + +### 🙏 Keep Reporting Bugs + +We truly value your feedback.

The **AFS (All Format Support)** branch makes its debut, providing **permanent support** for the Opus audio format for the first time! + +But before excitement takes over, we must be honest with you: + +**This is a pre-release version.** + +What does that mean? It means: + +✅ All core features are implemented and tested +✅ 229 Opus-specific tests all pass +✅ Cross-platform (Windows/Linux/macOS) playback verified +⚠️ Some edge-case bugs may still exist that we haven't found +⚠️ We need real users to test in diverse environments + +So we're giving this version to **you** — our users — to help us test. + +> **"AFS is the permanent home of Opus and all future new formats."** + +This is part of ap_ds's dual-track strategy. We'll explain in detail in the following sections. + +--- + +## 🚨 Important Notes on Version 0.0.1-AFS Positioning + +### 1. This is a Pre-release + +0.0.1-AFS is **not** an LTS or final stable version. It is a **pre-release** aimed at: + +- Collecting real-world usage feedback +- Discovering edge-case bugs not covered by tests +- Verifying cross-platform compatibility +- Gathering data for the 1.0.0 stable release + +### 2. AFS Branch — The Permanent Home of Opus + +This is a critical statement: + +**The AFS branch is the permanent home for Opus and all future new formats.** + +Unlike the mainline (`ap-ds` 4.x), the AFS branch will **permanently retain** Opus support and continuously add new formats. + +| Version | Opus Support | Description | +|---------|-------------|-------------| +| 0.0.1-AFS | ✅ Yes | First AFS pre-release | +| 1.0.0 (Sep 2026) | ✅ Yes | First AFS stable release | +| Future AFS | ✅ Yes | Permanent support | +| Mainline 4.2.0+ | ❌ No | Returns to lightweight positioning | + +**Why?** + +Because ap_ds mainline's core promise is **2.5MB lightweight**. Opus support (including DLLs) pushes the size to ~3.87MB. Mainline will remove Opus to return to 2.5MB. The AFS branch is specifically designed to carry Opus and future formats, at ~2.8-3.5MB. + +So if you need Opus support: + +- **Short-term testing:** Use 0.0.1-AFS pre-release +- **Long-term use:** Use AFS branch (`pip install ap-ds-afs`), with 1.0.0 stable coming in September +- Both packages use **identical imports** (`from ap_ds import AudioLibrary`) — zero migration cost + +### 3. Bug Reporting & Fix Commitment + +If you find any issues with 0.0.1-AFS: + +📧 me@dvsyun.top +📧 dvs6666@163.com (CC both for delivery guarantee) + +**We promise:** +- Fix within **3 business days** +- Patch releases will be published promptly + +**When reporting, please provide:** +- OS and version +- Python version (`python --version`) +- Full error message (if any) +- Reproduction steps +- Audio file sample (if possible) + +Every piece of feedback helps us build a better ap_ds. 🙏 + +--- + +## 🤔 Why Opus? — The Technical Imperative + +### 1. Quality & Compression Ceiling + +Opus is an open audio codec jointly developed by the Xiph.Org Foundation and IETF, combining SILK (speech) and CELT (general audio) algorithms with adaptive bitrate from 6 kbps to 510 kbps. This means: + +- At low bitrates (<32 kbps), Opus voice clarity far exceeds MP3 and AAC +- At medium-high bitrates (64-128 kbps), Opus quality matches or exceeds MP3 at 320kbps +- Ultra-low latency (as low as 5ms), ideal for real-time communication and gaming + +### 2. Open Source & Freedom — A Philosophical Fit + +Opus uses a BSD-like license with **no patent restrictions**, completely free. This aligns perfectly with ap_ds's commitment to openness, freedom, and zero burden. + +### 3. Mature Ecosystem & Clear Demand + +Opus is widely used in: +- **WebRTC** (real-time audio/video communication) +- **Discord, WhatsApp, Signal** and other instant messaging apps +- **Game engines** (Unity, Unreal both support Opus) +- **Audio streaming** (broadcasting, podcasting) +- **Embedded devices** (low power, high compression) + +As more audio content is published in Opus format, ap_ds as a general-purpose audio library must respond to this trend. + +### 4. Paving the Way for the AFS Branch + +Opus is the first member of the AFS (All Format Support) branch. Through the 0.0.1-AFS pre-release, we validate cross-platform Opus playback solutions and accumulate experience for the 1.0.0 stable release. + +--- + +## 😅 Why Didn't We Support Opus Before? — The Upstream Dependency Story + +This is a great question. Honestly, we've wanted to support Opus since ap_ds v1.0. But the reality is: + +ap_ds has always relied on **SDL2 and SDL2_mixer** for audio playback. + +SDL2 is an excellent cross-platform multimedia library that handles audio device abstraction, mixing, and buffering across Windows, macOS, and Linux. SDL2_mixer supports MP3, WAV, OGG, FLAC and other formats out of the box. + +But the problem is — **SDL2_mixer's Opus support was never stable enough.** + +| Platform | Issue | +|----------|-------| +| Windows | Official SDL2_mixer Windows binaries often lack Opus support or have incomplete compile flags, causing `Mix_LoadMUS` to return NULL for `.opus` files | +| macOS | SDL2_mixer Framework builds frequently have version mismatches and `libopusfile`/`libogg` dependency issues, causing runtime crashes | +| Linux | SDL2_mixer depends on system-installed `libopusfile-dev`, but package names and versions vary widely across distributions | +| API Inconsistency | Even when Opus loads, SDL2_mixer's metadata extraction (duration, bitrate, etc.) often returns 0 or errors | + +We tried multiple approaches: + +- Compiling our own Opus-enabled SDL2_mixer binaries → Bloated, high maintenance cost +- Forcing users to install `libopusfile-dev` on Linux → Poor UX, and Windows/macOS issues remained +- Waiting for upstream SDL2_mixer fixes across multiple versions → Issues persisted + +**Conclusion:** SDL2_mixer's upstream support was insufficient to provide stable Opus playback. + +Therefore, before AFS, we made a difficult decision — **temporarily not support Opus** to avoid giving users an unstable experience. + +### How Does 0.0.1-AFS Solve This? + +**Because SDL2 doesn't work, we decided to not use SDL2 at all!** + +In the AFS branch, we completely bypass SDL2 and SDL2_mixer, building a **dedicated playback pipeline** for Opus: + +``` +User passes .opus file + ↓ + Detects .opus extension + ↓ + libopusfile decodes + ↓ + Cross-platform audio output engine + ├── Windows → winmm waveOut + ├── Linux → ALSA (libasound.so) + └── macOS → Core Audio AudioQueue + ↓ + Audio output to speakers +``` + +This pipeline is **completely independent of SDL2**, free from SDL2_mixer's limitations. + +Meanwhile, Windows users don't need to hunt for DLLs — ap_ds automatically downloads the required four DLLs (`libopusfile-0.dll`, `libopus-0.dll`, `libogg-0.dll`, `libopusurl-0.dll`) on first run with **SHA256 hash verification** ensuring file integrity. + +This is why AFS can support Opus, and why we couldn't before. It's not that we didn't want to — we had to find a reliable, stable, truly cross-platform solution. Now we have one. + +--- + +## 🧬 Technical Deep Dive — What We Actually Did + +### 1. New Modules & Architecture + +To integrate Opus support without affecting mainline stability, we carefully designed the project structure: + +| File | Responsibility | Description | +|------|---------------|-------------| +| `opusplayer.py` | Opus playback core | `OpusAudio` class — fully independent of SDL2, encapsulates all Opus playback, control, metadata and batch APIs | +| `_opusdll.py` | Opus library loader | Cross-platform loading (Windows auto-download, Linux/macOS system detection + install guide), unified libopusfile client | +| `player.py` (modified) | Opus routing integration | `AudioLibrary` auto-detects `.opus` files and forwards to `OpusAudio` sub-player, fully transparent playback | +| `__init__.py` (modified) | Export OpusAudio | Users can use `from ap_ds import OpusAudio` directly or seamlessly through `AudioLibrary` | + +**Key Design: AID 1:1 Mapping** + +When a user plays via `AudioLibrary.play_from_file("song.opus")`, the library internally creates an `OpusAudio` instance and generates a sub-AID, then maps the main library AID to the sub-library AID via a dictionary. All subsequent controls (pause, resume, volume, seek) route correctly to the Opus engine, completely transparent to user code. + +```python +# User code — exactly the same as before! +from ap_ds import AudioLibrary + +lib = AudioLibrary() +aid = lib.play_from_file("song.opus") # Auto-routed to Opus engine +lib.pause_audio(aid) # Auto-routed to Opus engine +lib.seek_audio(aid, 30.0) # Auto-routed to Opus engine +lib.stop_audio(aid) # Auto-routed to Opus engine +``` + +**Fully transparent, zero learning curve.** + +### 2. Cross-Platform Playback Backends — Three Platform Engines Rewritten for Opus + +Opus playback cannot rely on SDL2, so we decided to completely bypass SDL2 and use native OS audio APIs directly with `libopusfile` decoding. + +| Platform | Playback Solution | Tech Stack | +|----------|------------------|------------| +| **Windows** | winmm waveOut | libopusfile decode → waveOutWrite multi-buffer (4 buffers, 50ms/block) | +| **Linux** | ALSA | libasound.so.2 → snd_pcm_open → snd_pcm_writei (direct PCM output) | +| **macOS** | Core Audio AudioQueue | Apple official C API → AudioQueue callback fill (consistent with official examples) | + +**Platform Implementation Details:** + +**Windows** (`_play_worker_windows`): +- Uses `waveOutOpen` to open default audio device +- Uses `CreateEventW` + `WaitForSingleObject` for buffer completion synchronization +- 4 buffers rotating to eliminate stuttering +- `WAVEHDR` structure with `c_void_p` for 64-bit compatibility + +**Linux** (`_play_worker_linux`): +- Uses `snd_pcm_open` with "default" device +- Uses `snd_pcm_set_params` for PCM parameters (S16_LE, interleaved mode) +- Uses `snd_pcm_writei` for PCM data write +- On `-EPIPE` (buffer underrun), calls `snd_pcm_recover` for auto-recovery + +**macOS** (`_play_worker_macos`): +- Uses `AudioQueueNewOutput` to create output queue +- Uses `AudioQueueAllocateBuffer` for buffer allocation +- Callback `HandleOutputBuffer` decodes Opus and fills `mAudioData` +- Uses `AudioQueueStart` to start, `AudioQueueStop` to stop + +### 3. Opus-Specific Error Codes (2001-2010) + +To make Opus-related errors clearer and more traceable, we added 10 dedicated error codes: + +| Code | Constant | Meaning | Suggested Action | +|------|----------|---------|-----------------| +| 2001 | AP_DS_ERR_OPUS_LIB_LOAD_FAILED | libopusfile load failed | Check DLL existence/locks | +| 2002 | AP_DS_ERR_OPUS_DLL_DEPENDENCY | DLL dependency missing | Ensure libopus-0.dll and libogg-0.dll exist | +| 2003 | AP_DS_ERR_OPUS_OPEN_FAILED | Opus file open failed | File may be corrupted or not valid Opus | +| 2004 | AP_DS_ERR_OPUS_HEADER_CORRUPT | OpusHead header corrupt | Invalid or corrupted header info | +| 2005 | AP_DS_ERR_OPUS_TAGS_PARSE_FAILED | Tag parse failed | Corrupted or invalid tag data | +| 2006 | AP_DS_ERR_OPUS_DECODE_FAILED | Opus decode failed | Corrupted audio data | +| 2007 | AP_DS_ERR_OPUS_SEEK_FAILED | Opus seek failed | Stream may not support seeking to this position | +| 2008 | AP_DS_ERR_OPUS_BITRATE_UNAVAILABLE | Bitrate unavailable | Cannot determine bitrate for this Opus stream | +| 2009 | AP_DS_ERR_OPUS_NOT_SEEKABLE | Stream not seekable | This Opus stream doesn't support seeking | +| 2010 | AP_DS_ERR_OPUS_CHANNEL_INVALID | Invalid channel count | Invalid channel count in Opus stream | + +All Opus errors include: +- Machine-readable error code (for programmatic handling) +- Human-readable error message (for developer understanding) +- Actionable suggestion (for user problem resolution) + +### 4. Auto DLL Download & Hash Verification (Windows) + +Windows users don't need to manually find DLLs. When ap_ds first detects Opus support is needed, it: + +1.

Your program's ability to run depends on it. + +**What's the problem?** + +On Windows, Python's `multiprocessing` module uses the `spawn` method to create new processes. This means each child process re-imports your main module. + +If you call `batch_get_metadata()` or any batch function that uses `ProcessPoolExecutor` directly at the top level of your script, child processes will execute these calls again when re-importing, causing infinite recursion and eventually a `BrokenProcessPool` error. + +**Your program will crash. Directly.** + +**Affected APIs:** +- `batch_get_metadata()` +- `batch_get_duration()` +- `batch_get_metadata_by_type()` +- Opus batch parsing is also affected + +**How to fix?** + +Simply wrap your batch parsing code inside `if __name__ == "__main__":`. + +**❌ Wrong (Will crash on Windows):** +```python +from ap_ds import batch_get_metadata + +# This will crash directly on Windows! +results = batch_get_metadata("/music/", max_workers=4) +print(f"Parsed {len(results)} files") +``` + +**✅ Correct:** +```python +from ap_ds import batch_get_metadata + +def main(): + results = batch_get_metadata("/music/", max_workers=4) + print(f"Parsed {len(results)} files") + +if __name__ == "__main__": + main() +``` + +**✅ Correct (with config function):** +```python +from ap_ds import batch_get_metadata + +def load_config(): + return {"audio_dir": "/music/"} + +def main(): + config = load_config() + results = batch_get_metadata(config["audio_dir"], max_workers=4) + print(f"Parsed {len(results)} files") + +if __name__ == "__main__": + main() +``` + +**✅ Jupyter Notebook Users:** +Put the batch call inside a function, then execute it in a cell: +```python +def run_batch(): + from ap_ds import batch_get_metadata + return batch_get_metadata("/music/", max_workers=4) + +results = run_batch() +``` + +**Why don't Linux and macOS have this problem?** + +Linux and macOS use `fork` by default to create child processes, which copy the parent process's memory space without re-executing the main module code. + +However, we still recommend using `if __name__ == "__main__"` entry point protection on all platforms.
