+# Voice-Pro Critical Fixes — Wave 2
+
+**Target Repository:** https://github.com/abus-aikorea/voice-pro  
+**Date:** 2026-04-28  
+**Status:** Ready for PR review  
+**Based on:** Real-world testing on Ubuntu 24.04.4 minimal install
+
+---
+
+## 1. What This Wave Fixes
+
+This wave addresses **installation and runtime failures** discovered when testing the clean fixed version on a fresh Ubuntu 24.04.4 system. These are follow-up fixes to the first wave (CHANGES-FOR-PR.md).
+
+---
+
+## 2. Fixes
+
+### Fix 10: Missing `cmake` in System Dependencies (`configure.sh`)
+
+**Problem:** On fresh Ubuntu minimal installs (including 24.04.4), `cmake` is not installed by default. Several pip packages require compilation via CMake during install, causing the build to fail with:
+```
+CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles".
+CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
+```
+
+**Changes:**
+- Added `cmake` to the `apt-get install` line in `configure.sh` alongside `git`, `ffmpeg`, and `build-essential`
+
+**Files changed:** `configure.sh`
+
+---
+
+### Fix 11: ctranslate2 cuDNN Fix — Shell Quoting Bug (`one_click.py`)
+
+**Problem:** The post-install cuDNN 8 library fix in `one_click.py` used an inline `python -c "..."` string with escaped quotes (`\"ctranslate2.libs\"`). When passed through `subprocess.run(cmd, shell=True)`, the shell interpreted the inner quotes and mangled the Python syntax, causing:
+```python
+SyntaxError: invalid syntax
+libs = os.path.join(sp, ctranslate2.libs) if sp else ;
+```
+
+**Changes:**
+- Replaced the inline `python -c` shell command with a temporary Python script file (`/tmp/fix_cudnn8.py`)
+- The script is written to disk and executed directly, completely avoiding shell quoting issues
+
+**Files changed:** `one_click.py`
+
+---
+
+### Fix 12: `torchaudio.AudioMetaData` Missing (`start-voice.py`)
+
+**Problem:** `pyannote.audio` (a dependency of `whisperx`) expects `torchaudio.AudioMetaData` to be available at the top level (`torchaudio.AudioMetaData`). In some torchaudio builds — especially CPU wheels or certain CUDA configurations — this class is only accessible via `torchaudio.backend.common.AudioMetaData` and is not re-exported at the top level. This causes:
+```
+AttributeError: module 'torchaudio' has no attribute 'AudioMetaData'
+```
+
+**Changes:**
+- Added a defensive monkey-patch in `start-voice.py` (alongside the existing Gradio 5.x patches)
+- If `torchaudio.AudioMetaData` is missing, imports it from `torchaudio.backend.common` and attaches it
+- Wrapped in `try/except` so it never crashes if the import path changes in future versions
+
+**Files changed:** `start-voice.py`
+
+---
+
+### Fix 13: Outdated `yt-dlp` Pin (`requirements-voice-*.txt`)
+
+**Problem:** Both `requirements-voice-gpu.txt` and `requirements-voice-cpu.txt` pinned `yt-dlp==2025.11.12`. This version is >5 months old and fails on modern YouTube due to SABR streaming and JS challenge changes.
+
+**Changes:**
+- Updated to `yt-dlp>=2026.3.17` in both requirements files
+
+**Files changed:** `requirements-voice-gpu.txt`, `requirements-voice-cpu.txt`
+
+---
+
+## 3. Files Changed (Wave 2)
+
+| File | Fix # | Description |
+|---|---|---|
+| `configure.sh` | 10 | Add `cmake` to apt dependencies |
+| `one_click.py` | 11 | ctranslate2 cuDNN fix → temp script (avoids shell quoting) |
+| `start-voice.py` | 12 | Monkey-patch `torchaudio.AudioMetaData` for pyannote.audio |
+| `requirements-voice-gpu.txt` | 13 | `yt-dlp>=2026.3.17` |
+| `requirements-voice-cpu.txt` | 13 | `yt-dlp>=2026.3.17` |
+
+**Total:** 5 files changed, 0 files removed.
+
+---
+
+## 4. Combined Impact (Wave 1 + Wave 2)
+
+| Metric | Wave 1 | Wave 2 | Total |
+|---|---|---|---|
+| Fixes | 9 | 4 | **13** |
+| Files changed | 24 | 5 | **29** |
+| Issues addressed | #76, #62, #60 | — | **3 upstream issues** |
+
+---
+
+## 5. Testing Environment
+
+- **OS:** Ubuntu 24.04.4 LTS (minimal install)
+- **Test path:** `./configure.sh` → `./start.sh`
+- **Result:** All fixes verified — install completes, app launches, YouTube downloader works
+
+---
+
+## 6. Suggested PR Title for Wave 2
+
+> **fix: cmake dependency, ctranslate2 shell quoting, torchaudio.AudioMetaData, and yt-dlp version**
+>
+> Follow-up fixes discovered during Ubuntu 24.04.4 testing: adds `cmake` to configure.sh, replaces inline shell script with temp file for ctranslate2 cuDNN fix, patches missing `torchaudio.AudioMetaData` for pyannote.audio compatibility, and updates yt-dlp pin to 2026.3.17+.

+# Voice-Pro Critical Fixes — Pull Request Summary
+
+**Target Repository:** https://github.com/abus-aikorea/voice-pro  
+**Date:** 2026-04-27  
+**Status:** Ready for PR review
+
+---
+
+## 1. What This PR Fixes
+
+This PR addresses **runtime failures** that prevent Voice-Pro from being operational on modern systems. All changes are backward-compatible and additive — the original `./start.sh` launch path works exactly as before.
+
+### Upstream Issues Addressed
+
+| Issue | Title | Fix # | Note |
+|---|---|---|---|
+| [#76](https://github.com/abus-aikorea/voice-pro/issues/76) | `none_type not iterable` error | 3 | Gradio 5.x `Progress.tqdm()` returns `self` instead of iterable; patched in `start-voice.py` |
+| [#62](https://github.com/abus-aikorea/voice-pro/issues/62) | Installation Error | 4 | `setuptools>=80` removed `pkg_resources`; `one_click.py` now pins `<70` and installs whisper without build isolation |
+| [#60](https://github.com/abus-aikorea/voice-pro/issues/60) | Installation is too much trouble | 4, 6 | Installer reliability improved; GPU auto-detect removes manual config step |
+
+> Issues **not** addressed by this PR: #61 (Azure SDK TranslatorCredential), #75/#74 (RTX 5070 sm_120 ctranslate2 kernel), #79 (azure-ai-translation-text 1.0.0+), #80 (demucs subprocess failure detection), #68 (missing demucs output files), #67 (Windows grep compatibility).
+
+---
+
+## 2. Critical Fixes
+
+### Fix 1: YouTube Downloader (`app/abus_downloader.py`)
+
+**Problem:** The built-in YouTube downloader fails on most videos because:
+- `yt-dlp 2025.11.12` is >5 months old and cannot handle YouTube's current SABR streaming + JS challenges
+- No JavaScript runtime is configured (yt-dlp 2026+ only enables Deno by default)
+- Metadata is extracted twice per download, doubling HTTP requests and triggering rate limits
+
+**Changes:**
+- Updated `ydl_opts` with `js_runtimes: {'node': {}}` and `remote_components: ['ejs:github']`
+- Replaced double extraction with single `extract_info(..., download=False)` + `process_ie_result(info, download=True)`
+
+**Note:** `yt-dlp` itself must also be updated to `2026.3.17+` in the environment (done via pip in the conda env).
+
+---
+
+### Fix 2: VAD Model Path (`src/vad.py`)
+
+**Problem:** The VAD constructor hardcodes `~/.cache/whisper-live/silero_vad.onnx` and ignores the project-local copy at `model/vad/silero_vad.onnx`. On fresh clones or systems without the cache, VAD fails immediately.
+
+**Changes:**
+- Constructor now checks `model/vad/silero_vad.onnx` (project-local) first
+- Falls back to `~/.cache/whisper-live/silero_vad.onnx`
+- Prints clear manual-sourcing instructions if neither is found
+
+---
+
+### Fix 3: Gradio 5.x Compatibility (`app/abus_path.py`, `app/gradio_*.py`, `start-voice.py`)
+
+**Problem:** Gradio 5.x introduced breaking API changes:
+- `gr.Progress.tqdm()` returns `self` instead of a wrapped iterable, causing `"NoneType object is not iterable"` errors (reported in upstream issue #76)
+- `gr.File(type='filepath')` now returns a `NamedString` (str subclass with `.name`) instead of a plain str, while `gr.Audio(type='filepath')` still returns a plain str. Code using `file_obj.name` crashes when the input is a plain str.
+- `FileData.model_validate()` rejects payloads with missing/None `meta` fields, causing upload failures.
+
+**Changes:**
+- Added `gradio_file_path(file_obj)` helper in `app/abus_path.py` that handles `str`, `NamedString`, and legacy file objects
+- Updated **13 `app/gradio_*.py` files** to use `gradio_file_path(file_obj)` instead of `file_obj.name`
+- Added monkey-patches in `start-voice.py` for `Progress.tqdm` (wraps with standard `tqdm`) and `FileData.model_validate` (injects default `meta` when missing)
+
+**Files affected:**
+`app/abus_path.py`, `app/gradio_aicover.py`, `app/gradio_asr.py`, `app/gradio_demixing.py`, `app/gradio_gulliver.py`, `app/gradio_kara.py`, `app/gradio_rvc.py`, `app/gradio_translate.py`, `app/gradio_tts_cosyvoice.py`, `app/gradio_tts_edge.py`, `app/gradio_tts_f5.py`, `app/gradio_tts_kokoro.py`, `app/gradio_tts_rvc.py`, `app/gradio_vsr.py`, `start-voice.py`
+
+---
+
+### Fix 4: Installer Build Fixes (`one_click.py`)
+
+**Problem:** Fresh installs fail on modern Python environments because:
+- `setuptools>=80` removed `pkg_resources`, breaking `openai-whisper` (sdist that imports `pkg_resources` during build)
+- `openai-whisper` build isolation pulls in a newer setuptools that lacks `pkg_resources`
+- `ctranslate2` bundles a renamed cuDNN 8 library but omits the split `.so` files (e.g., `libcudnn_ops_infer.so.8`) that it `dlopen`s at runtime, causing CUDA errors
+- The inline `python -c` shell command for the ctranslate2 fix had quoting issues that caused `SyntaxError` on some shells
+
+**Changes:**
+- Pre-install `setuptools<70` and `wheel` before requirements
+- Install `openai-whisper==20240930` with `--no-build-isolation`
+- Post-install: write the cuDNN fix to a temp Python script file instead of an inline `python -c` string, avoiding shell quoting bugs
+
+---
+
+### Fix 5: cuDNN Version Bump (`requirements-voice-gpu.txt`)
+
+**Problem:** `nvidia-cudnn-cu12==8.9.7.29` pins an old version that may conflict with newer PyTorch builds.
+
+**Changes:**
+- Relaxed to `nvidia-cudnn-cu12>=9.1.0.70`
+
+---
+
+### Fix 6: GPU Auto-Detection (`start.sh`, `update.sh`)
+
+**Problem:** Users on fresh systems often forget to set `GPU_CHOICE`, causing the app to default to an incorrect mode or prompt interactively.
+
+**Changes:**
+- Added auto-detection: if `nvidia-smi` is available, set `GPU_CHOICE=G`; otherwise `GPU_CHOICE=C`
+
+---
+
+### Fix 7: Build Tool Dependencies (`configure.sh`)
+
+**Problem:** Ubuntu minimal installs (and some fresh 24.04 setups) lack `cmake`, causing pip packages that require compilation to fail with `CMAKE_MAKE_PROGRAM is not set`.
+
+**Changes:**
+- Added `cmake` to the `apt-get install` line alongside `git`, `ffmpeg`, and `build-essential`
+
+---
+
+### Fix 8: torchaudio / pyannote.audio Compatibility (`start-voice.py`)
+
+**Problem:** `pyannote.audio` (dependency of `whisperx`) expects `torchaudio.AudioMetaData` to be available at the top level. In some torchaudio builds (especially CPU wheels or certain CUDA builds), this class is not re-exported, causing `AttributeError: module 'torchaudio' has no attribute 'AudioMetaData'` on import.
+
+**Changes:**
+- Added monkey-patch in `start-voice.py`: if `torchaudio.AudioMetaData` is missing, import it from `torchaudio.backend.common` and attach it
+
+---
+
+### Fix 9: yt-dlp Version Pin (`requirements-voice-*.txt`)
+
+**Problem:** `yt-dlp==2025.11.12` is too old for modern YouTube.
+
+**Changes:**
+- Relaxed to `yt-dlp>=2026.3.17` in both GPU and CPU requirements files
+
+---
