yt-dlp --cookies /root/cookies.txt -x --audio-format mp3 -o "song.%(ext)s" --remote-components ejs:github "https://youtu.be/pXXJPSR7ugQ"

Assistant

I’ve tried every automated method available to me to fetch the YouTube video (or its audio) at the links you’ve given:

- yt-dlp with cookie injection (/root/cookies.txt)
- --remote-components ejs:github flag
- Alternative extractors (android, iOS, mweb, generic)
- Alternative front‑ends (yewtu.be, piped.video, inv.nadeko.net, etc.)
- Browser‑based navigation and interaction with online converter sites (Typito, YTMP3, etc.)

All attempts return the same error: **“Sign in to confirm you’re not a bot” / LOGIN_REQUIRED** (HTTP 403/429). Even when I manage to load a YouTube page in the browser, the session is immediately redirected to a Chrome “New Incognito Tab” page, indicating that the request is being intercepted before the video page can be rendered.

Because I cannot retrieve the source audio/video, I’m unable to perform the trimming step (10:35 → 13:51) automatically.

---

### How we can move forward

1. **You provide the file** – If you download the audio (or video) from YouTube by any means you prefer (e.g., a browser extension, a desktop tool such as yt-dlp on your own machine, or a manual converter site), you can upload it here, and I’ll immediately trim the segment **10:35‑13:51** using ffmpeg and return the result as a downloadable attachment.

2. **Alternative source** – If the same track is available on another platform (SoundCloud, Bandcamp, etc.) that doesn’t trigger the bot‑detect block, share that link and I’ll try to download from there.

3. **Local command** – If you have yt‑dlp and ffmpeg on your own machine, you can run:
``bash
yt-dlp -x --audio-format mp3 -o "song.%(ext)s" "https://youtu.be/6IGMxIg_AjI?is=MzkBLULXRxifLB1D"
ffmpeg -ss 00:10:35 -to 00:13:51 -i song.mp3 -c copy trimmed.mp3
`
and then share trimmed.mp3 with me if you need any further processing.

Once I have the source file (in any common audio/video format), I’ll use ffmpeg` to cut the requested interval and deliver the trimmed clip.

Please let me know how you’d like to proceed!

show me how to formate the command for commandline using the cookies file

Assistant

Here’s the exact syntax you need to tell **yt‑dlp** to load a Netscape‑format cookies file and then download/extract the audio you want.

### 1. Basic command (download‑only, keep original container)

``bash
yt-dlp --cookies /root/cookies.txt "https://youtu.be/6IGMxIg_AjI?is=MzkBLULXRxifLB1D"
`

### 2. Extract audio to MP3 (the -x / --extract-audio flag)

`bash
yt-dlp \
--cookies /root/cookies.txt \ # ← path to your cookies.txt (Netscape format)
-x \ # extract audio only
--audio-format mp3 \ # convert to mp3 after download
-o "song.%(ext)s" \ # output template (song.mp3 will be created)
"https://youtu.be/6IGMxIg_AjI?is=MzkBLULXRxifLB1D"
`

### 3. Trim the downloaded MP3 to the interval you want (10:35 → 13:51)

After the audio file is on disk (song.mp3), you can cut it with **ffmpeg**:

`bash
ffmpeg -ss 00:10:35 -to 00:13:51 -i song.mp3 -c copy trimmed.mp3
`

* -ss = start time
* -to = end time (exclusive)
* -c copy = stream‑copy (no re‑encode, so it’s instant and lossless)

### 4. One‑liner (download + extract + trim) – if you prefer to do it all in a single shell line

`bash
yt-dlp --cookies /root/cookies.txt -x --audio-format mp3 \
-o "song.%(ext)s" "https://youtu.be/6IGMxIg_AjI?is=MzkBLULXRxifLB1D" \
&& ffmpeg -ss 00:10:35 -to 00:13:51 -i song.mp3 -c copy trimmed.mp3
`

---

#### What the cookies file should look like

yt‑dlp expects a **Netscape HTTP Cookie File** (the format browsers export). A minimal example:

`
# Netscape HTTP Cookie File
# This file is generated by yt-dlp. Do not edit.

.youtube.com TRUE / FALSE 0 PREF f4=4000000&tz=UTC&hl=en
.youtube.com TRUE / TRUE 1798827538 VISITOR_INFO1_LIVE iMS9ljNWXeg
...
`

* Lines starting with # are comments and are ignored.
* Each data line has seven tab‑separated fields:
domain flag path secure expiration name value

If you already have /root/cookies.txt in that format, just point yt‑dlp at it with --cookies /root/cookies.txt as shown above.

---

### Quick checklist before you run

1. **Cookies are fresh** – YouTube rotates its auth cookies frequently. If you see the “Sign in to confirm you’re not a bot” error, export a new cookies file from your browser (Chrome/Chromium → Settings → Privacy → Cookies → Export) and replace /root/cookies.txt.
2. **File permissions** – Make sure the file is readable by the user running yt‑dlp (chmod 600 /root/cookies.txt is typical).
3. **yt‑dlp version** – Keep it up‑to‑date (pip install -U yt-dlp`) because YouTube’s anti‑bot measures change often.

That’s all you need to format the command line with a cookies file. Let me know if you run into any specific error and we can troubleshoot the exact output!

The audio has been downloaded, extracted to MP3, and trimmed to the requested segment (10:35 – 13:51). The resulting file **trimmed.mp3** (~3 MB) has been sent to your Discord home channel as an attachment.

You can download it directly from there. Let me know if you need any further processing (e.g., different format, volume adjustment, etc.).

I’ve saved a reusable skill called **youtube-audio-trim** (under the devops category) that captures the exact steps we just used:

1. **Export a fresh YouTube cookies file** (Netscape format) from your logged‑in browser and store it somewhere, e.g. /root/cookies.txt.
2. **Run the skill** (or just follow the commands it contains) for any YouTube URL:
``bash
# Download audio only, convert to mp3
yt-dlp --cookies /root/cookies.txt -x --audio-format mp3 -o "song.%(ext)s" "YOUR_YOUTUBE_URL"

# Trim to the desired interval (HH:MM:SS or MM:SS)
ffmpeg -ss START_TIME -to END_TIME -i song.mp3 -c copy trimmed.mp3
`
Example for 10:35 → 13:51:
`bash
ffmpeg -ss 00:10:35 -to 00:13:51 -i song.mp3 -c copy trimmed.mp3
`

You can also run the two commands together as a one‑liner:
`bash
yt-dlp --cookies /root/cookies.txt -x --audio-format mp3 -o "song.%(ext)s" "YOUR_YOUTUBE_URL" \
&& ffmpeg -ss START_TIME -to END_TIME -i song.mp3 -c copy trimmed.mp3
`

The skill also includes troubleshooting tips (refreshing cookies if you see “Sign in to confirm you’re not a bot”, using --remote-components ejs:github for JavaScript challenges, etc.).

Whenever you need to repeat this process for a new YouTube link, just load the skill with:
`bash
skill_view(name='youtube-audio-trim')
``
…or simply recall the steps above. Let me know if you’d like me to run it on a new link now!
