# Supported File Types for Upload

The SocialSyncs CLI now correctly detects and uploads various media types.

## How It Works

The CLI automatically detects the MIME type based on the file extension:

```bash
socialsyncs upload video.mp4
# ✅ Detected as: video/mp4

socialsyncs upload image.png
# ✅ Detected as: image/png

socialsyncs upload audio.mp3
# ✅ Detected as: audio/mpeg
```

### Other Files

For file types not listed above, the CLI uses:
- MIME type: `application/octet-stream`
- This is a generic binary file type

## Usage Examples

### Upload an Image

```bash
socialsyncs upload ./images/photo.jpg
```

Response:
```json
{
  "id": "upload-123",
  "path": "https://cdn.socialsyncs.co/uploads/photo.jpg",
  "url": "https://cdn.socialsyncs.co/uploads/photo.jpg"
}
```

### Upload a Video (MP4)

```bash
socialsyncs upload ./videos/promo.mp4
```

Response:
```json
{
  "id": "upload-456",
  "path": "https://cdn.socialsyncs.co/uploads/promo.mp4",
  "url": "https://cdn.socialsyncs.co/uploads/promo.mp4"
}
```

### Upload and Use in Post

```bash
# 1. Upload the file
RESULT=$(socialsyncs upload video.mp4)
echo $RESULT

# 2. Extract the path (you'll need jq or similar)
PATH=$(echo $RESULT | jq -r '.path')

# 3. Use in a post
socialsyncs posts:create \
  -c "Check out my video!" \
  -m "$PATH" \
  -i "tiktok-123"
```

### Upload Multiple Files

```bash
# Upload images
socialsyncs upload image1.jpg
socialsyncs upload image2.png
socialsyncs upload image3.gif

# Upload videos
socialsyncs upload video1.mp4
socialsyncs upload video2.mov
```

## What Changed (Fix)

### Before (❌ Bug)

```bash
socialsyncs upload video.mp4
# ❌ Was detected as: image/jpeg (WRONG!)
```

The problem: The CLI defaulted to `image/jpeg` for any unknown file type.

### After (✅ Fixed)

```bash
socialsyncs upload video.mp4
# ✅ Correctly detected as: video/mp4

socialsyncs upload audio.mp3
# ✅ Correctly detected as: audio/mpeg

socialsyncs upload document.pdf
# ✅ Correctly detected as: application/pdf
```

## Troubleshooting

### "Upload failed: Unsupported file type"

Some platforms may not accept certain file types. Check the platform's documentation.

**Solution:** Convert the file to a supported format:

```bash
# Convert video to MP4
ffmpeg -i video.avi video.mp4

# Then upload
socialsyncs upload video.mp4
```

### File Size Limits

Different platforms have different file size limits:

- **Twitter/X**: Max 512MB for videos
- **Instagram**: Max 100MB for videos
- **TikTok**: Max 287.6MB for videos
- **YouTube**: Max 128GB (but 256GB for verified)

### "MIME type mismatch"

If you renamed a file with the wrong extension:

```bash
# ❌ Wrong: PNG file renamed to .jpg
mv image.png image.jpg
socialsyncs upload image.jpg  # Might fail

# ✅ Correct: Keep original extension
socialsyncs upload image.png
```

## Testing File Upload

```bash
# Set API key
export SOCIALSYNCS_API_KEY=your_key

# Test image upload
socialsyncs upload test-image.jpg

# Test video upload
socialsyncs upload test-video.mp4

# Test audio upload
socialsyncs upload test-audio.mp3
```

## Error Messages

### File Not Found
```
❌ ENOENT: no such file or directory
```

**Solution:** Check the file path is correct.

### No Permission

```

**Solution:** Check file permissions:
```bash

```

### Invalid API Key
