FFmpeg wrapper scripts (Windows PowerShell)
=========================================

Purpose
-------
These scripts add the repository's bundled FFmpeg binary (under `ffmpeg-8.0-essentials_build/bin`) to the PATH for the current PowerShell session and provide a convenience launcher to run the Gradio app using that PATH.

Files
-----
- `add_ffmpeg_path.ps1` — Prepend the repo `ffmpeg-8.0-essentials_build/bin` folder to the current session PATH. Does not modify system PATH permanently.
- `run_app_with_ffmpeg.ps1` — Calls `add_ffmpeg_path.ps1`, optionally activates `.venv` if present, and runs `app.py` with the current Python.

Usage
-----
Open PowerShell in the repo root and run:

```powershell
# Make sure execution policy allows script running (temporary bypass)
powershell.exe -ExecutionPolicy Bypass -File .\scripts\run_app_with_ffmpeg.ps1
```

Or run `add_ffmpeg_path.ps1` directly to just update PATH in the session:

```powershell
. .\scripts\add_ffmpeg_path.ps1
# Now check ffmpeg
ffmpeg -version
```

Notes
-----
- These scripts only affect the current PowerShell session.
- If you prefer permanent PATH updates, add the ffmpeg bin folder to your system/user PATH.
- The app expects `GOOGLE_API_KEY` to be set (or a `.env` file with that variable) and the FAISS index/metadata files to be present.
