**ReClip shows "Video blocked due to copyright" when its backend `yt-dlp` process returns any error containing the substring "copyright", which can stem from actual DMCA takedowns, regional restrictions, age-gating, or outdated `yt-dlp` versions.**

ReClip is a lightweight web application that wraps `yt-dlp` to fetch video metadata and downloads. When users encounter the "Video blocked due to copyright" message, the error originates from `yt-dlp`'s underlying platform extraction—not from ReClip's code itself. Understanding this flow is essential for effective troubleshooting.

## How ReClip Generates the Copyright Error Message

The error propagation follows a clear path through the codebase:

### Frontend Request to Backend

The browser sends a POST request to `/api/info` or `/api/download` with the target video URL. In [`templates/index.html`](https://github.com/averygan/reclip/blob/main/templates/index.html), the JavaScript fetch call initiates this:

```javascript
fetch('/api/info', {
    method: 'POST',
    headers: {'Content-Type': 'application/json'},
    body: JSON.stringify({url: videoUrl})
})

```

*Source: [`templates/index.html`](https://github.com/averygan/reclip/blob/main/templates/index.html) lines 87-94*

### Backend Execution with yt-dlp

[`app.py`](https://github.com/averygan/reclip/blob/main/app.py) executes `yt-dlp` as a subprocess with `--no-playlist -j <url>` to extract JSON metadata:

```python
cmd = [YTDLP_PATH, '--no-playlist', '-j', url]
result = subprocess.run(cmd, capture_output=True, text=True, timeout=30)

```

*Source: [`app.py`](https://github.com/averygan/reclip/blob/main/app.py) lines 104-108*

### Error Propagation to Frontend

When `yt-dlp` exits with a non-zero status, the backend returns the final line of stderr as a JSON error:

```python
if result.returncode != 0:
    return jsonify({"error": result.stderr.strip().split("\n")[-1]})

```

*Source: [`app.py`](https://github.com/averygan/reclip/blob/main/app.py) lines 107-109*

### Friendly Error Mapping

The frontend's `friendlyError` function in [`templates/index.html`](https://github.com/averygan/reclip/blob/main/templates/index.html) converts any error containing "copyright" into the user-facing message:

```javascript
function friendlyError(err) {
    if (err.includes('copyright')) return 'Video blocked due to copyright';
    // ... other error mappings
}

```

## Common Causes of ReClip Copyright Errors

| Cause | Description | Quick Verification |
|-------|-------------|-------------------|
| **DMCA takedown** | Platform removed the video for copyright claims | Open URL in browser—shows "Video unavailable" |
| **Region lock** | Video unavailable in your geographic location | Try VPN or `yt-dlp --geo-bypass` |
| **Age restriction** | Content requires login or age verification | Check if incognito browser view prompts sign-in |
| **Content ID blocks** | Audio/video blocked by automated Content ID | Look for "Contains copyrighted content" warnings on platform |
| **Outdated yt-dlp** | Old extractors misidentify available videos | Run `pip install -U yt-dlp` |

## Step-by-Step Troubleshooting Guide

### 1. Inspect the Raw Backend Error

Test the `/api/info` endpoint directly to see the exact `yt-dlp` message:

```bash
curl -X POST -H "Content-Type: application/json" \
     -d '{"url":"https://www.youtube.com/watch?v=EXAMPLE"}' \
     http://localhost:8899/api/info

```

Expected response showing the underlying error:

```json
{"error":"Video unavailable. This video is not available because of a copyright claim by..."}

```

### 2. Run yt-dlp Directly

Bypass ReClip entirely to isolate whether the issue is with the video or the wrapper:

```bash
yt-dlp -j "https://www.youtube.com/watch?v=EXAMPLE"

```

- If output shows `{"error":"copyright"}` or similar → **issue is with the source video**
- If output returns valid JSON metadata → **check ReClip configuration**

### 3. Update yt-dlp to Latest Version

Many "false positive" copyright detections resolve with extractor updates:

```bash
pip install -U yt-dlp

```

Verify the update:

```bash
yt-dlp --version

```

Restart ReClip after updating to ensure it uses the new version.

### 4. Test Geographic Bypass Options

For region-locked content, try `yt-dlp`'s geo-bypass:

```bash
yt-dlp --geo-bypass -j "https://www.youtube.com/watch?v=EXAMPLE"

```

Or configure ReClip to run behind a VPN/proxy by setting environment variables before starting the application:

```bash
export HTTP_PROXY="http://proxy.example.com:8080"
export HTTPS_PROXY="http://proxy.example.com:8080"
python app.py

```

### 5. Verify Video Availability Manually

Open the URL in a private/incognito browser window. If the platform shows:

- "Video unavailable"
- "Removed due to copyright"
- "This video is not available in your country"

The video cannot be downloaded regardless of ReClip configuration.

### 6. Check Browser Developer Tools

While using ReClip's web interface:

1. Press **F12** to open developer tools
2. Go to **Network** tab
3. Submit a video URL
4. Find the `/api/info` request
5. Inspect the **Response** payload for the raw `error` field

This reveals whether the backend returned the expected error format.

## Key Files for Debugging ReClip Copyright Issues

| File | Purpose | Critical Lines |
|------|---------|--------------|
| [`app.py`](https://github.com/averygan/reclip/blob/main/app.py) | Backend error generation | Lines 97-109: subprocess execution and error JSON formatting |
| [`templates/index.html`](https://github.com/averygan/reclip/blob/main/templates/index.html) | Frontend error mapping | Lines 38-44: `friendlyError()` function |
| [`requirements.txt`](https://github.com/averygan/reclip/blob/main/requirements.txt) | Dependency version control | Specifies `yt-dlp` version constraints |

## Summary

- **ReClip copyright errors come from `yt-dlp`**, not from proprietary blocking logic
- The `friendlyError()` function in [`templates/index.html`](https://github.com/averygan/reclip/blob/main/templates/index.html) triggers on any error containing "copyright"
- **First diagnostic**: Run `yt-dlp -j <url>` directly to confirm source video status
- **Most common fixes**: Update `yt-dlp` with `pip install -U yt-dlp`, or use `--geo-bypass` for regional restrictions
- **No workaround exists** for legitimately DMCA-removed videos—respect platform takedowns

## Frequently Asked Questions

### Why does ReClip show "copyright" when the video plays fine in my browser?

Your browser may have cached credentials or regional routing that `yt-dlp` lacks. Try running `yt-dlp -j <url>` directly—if it fails, the issue is authentication or geo-blocking rather than an actual copyright takedown. Some platforms serve different content to logged-in vs. anonymous users.

### How do I update yt-dlp for ReClip?

Run `pip install -U yt-dlp` in the same Python environment where ReClip runs. Verify with `yt-dlp --version`, then restart the ReClip server. Check [`requirements.txt`](https://github.com/averygan/reclip/blob/main/requirements.txt) in the repository to ensure no version pinning conflicts exist.

### Can I bypass the copyright error in ReClip?

No—ReClip has no built-in bypass mechanism. The error originates from the video platform's response to `yt-dlp`. For false positives, updating `yt-dlp` often resolves extractor issues. For genuine copyright blocks, no legitimate workaround exists.

### Where does ReClip store error logs?

ReClip logs to stdout/stderr by default. For persistent logging, redirect output when starting the server: `python app.py > reclip.log 2>&1`. The browser's developer console (F12 → Network → `/api/info` Response) shows the frontend-received error in real time.
