# Development Rules
|
||||||
|
|
||||||
|
## Testing Requirements
|
||||||
|
- ALWAYS test code before claiming it's done
|
||||||
|
- Verify file uploads work with actual test files
|
||||||
|
- Check browser console for errors during testing
|
||||||
|
- Never say "done" without confirming functionality
|
||||||
|
- Run test scripts first before presenting solutions
|
||||||
|
|
||||||
|
## Known Issues
|
||||||
|
- MP4 video files may fail with AudioContext.decodeAudioData()
|
||||||
|
- Browser can't decode all video codecs to audio
|
||||||
|
- MediaRecorder approach for video extraction produces empty/unusable audio
|
||||||
|
- Solution: AudioContext.decodeAudioData works directly on many video formats

# Media to Text - Development Rules
|
||||||
|
|
||||||
|
## CRITICAL RULE: Never Upload Full Video Files
|
||||||
|
|
||||||
|
**Status**: MANDATORY - NEVER VIOLATE
|
||||||
|
|
||||||
|
### Rule Definition
|
||||||
|
- **NEVER** allow users to upload full video files (MP4, AVI, MOV, MKV, FLV, WMV, WEBM) to the server
|
||||||
|
- **ALWAYS** extract audio on the browser BEFORE uploading
|
||||||
|
- Only audio files (MP3, WAV, M4A, etc.) should be uploaded to the server
|
||||||
|
|
||||||
|
### Why This Rule Exists
|
||||||
|
1. **Bandwidth Efficiency**: Video files are 10-100x larger than extracted audio
|
||||||
|
2. **User Experience**: Faster uploads = better UX
|
||||||
|
3. **Server Resources**: Reduces server storage and processing load
|
||||||
|
4. **Cost**: Minimizes data transfer costs
|
||||||
|
|
||||||
|
### Implementation Requirements
|
||||||
|
- Browser-side audio extraction is MANDATORY for video files
|
||||||
|
- Use ffmpeg.wasm or equivalent WebAssembly solution
|
||||||
|
- If browser extraction fails, show error message - DO NOT fall back to uploading full video
|
||||||
|
- Server-side extraction is NOT acceptable as a workaround
|
||||||
|
|
||||||
|
### Current Status
|
||||||
|
- ❌ Browser extraction via ffmpeg.wasm: BLOCKED (CORS/CORB issues)
|
||||||
|
- ⚠️ Temporary workaround: Guide users to extract audio locally using ffmpeg CLI
|
||||||
|
- 🔄 TODO: Find working ffmpeg.wasm CDN or alternative solution
|
||||||
|
|
||||||
|
### Acceptable Solutions (In Priority Order)
|
||||||
|
1. ffmpeg.wasm from working CDN (no CORS/CORB issues)
|
||||||
|
2. Local ffmpeg.wasm with complete wasm binaries
|
||||||
|
3. Alternative WebAssembly video processing library
|
||||||
|
4. User-extracted audio files only (with clear instructions)
|
||||||
|
|
||||||
|
### NOT Acceptable
|
||||||
|
- ❌ Uploading full video files to server
|
||||||
|
- ❌ Server-side extraction as primary solution
|
||||||
|
- ❌ Removing this rule without explicit approval
|
||||||
|
|
||||||
|
## RULE: Show Model Download Progress
|
||||||
|
|
||||||
|
**Status**: MANDATORY
|
||||||
|
|
||||||
|
### Rule Definition
|
||||||
|
- **ALWAYS** show download progress when loading Whisper models
|
||||||
|
- Display percentage and/or file size being downloaded
|
||||||
|
- Models can be 150MB-500MB+ and take significant time to download
|
||||||
|
|
||||||
|
### Why This Rule Exists
|
||||||
|
1. **User Experience**: Users need to know the app isn't frozen
|
||||||
|
2. **Transparency**: Large downloads should be visible
|
||||||
|
3. **Expectations**: Users can estimate wait time
|
||||||
|
|
||||||
|
### Implementation Requirements
|
||||||
|
- Use progress callback from transformers.js pipeline
|
||||||
|
- Display progress percentage in status element
|
||||||
|
- Show "Downloading model: X%" or similar message

# Media to Text Converter
|
||||||
|
|
||||||
|
Convert audio files to text locally or in the browser.
|
||||||
|
|
||||||
|
## Browser Usage
|
||||||
|
|
||||||
|
Open `index.html` in Chrome or Edge:
|
||||||
|
- **Upload Audio**: Select an audio file (MP3, WAV, M4A, etc.) for transcription
|
||||||
|
- **Live Recording**: Click "Start Recording" to record and transcribe live audio
|
||||||
|
|
||||||
|
## Local Usage (Python)
|
||||||
|
|
||||||
|
For transcribing audio files using Python.
|
||||||
|
|
||||||
|
Install dependencies:
|
||||||
|
```bash
|
||||||
|
pip install -r requirements.txt
|
||||||
|
```
|
||||||
|
|
||||||
|
Transcribe a file:
|
||||||
|
```bash
|
||||||
|
python transcribe.py audio.mp3
|
||||||
|
```
|
||||||
|
|
||||||
|
## Server Mode
|
||||||
|
|
||||||
|
Run Flask server for API access:
|
||||||
|
```bash
|
||||||
|
python server.py
|
||||||
|
```
|
||||||
|
|
||||||
|
Server runs on http://127.0.0.1:5000
|
||||||
|
|
||||||
|
**Note**: Server only accepts audio files (not video) per project rules.
