This is an python API which allows you to get the transcripts/subtitles for a given YouTube video. It also works for automatically generated subtitles, supports translating subtitles and it does not require a headless browser, like other selenium based solutions do!

## CLI
Execute the CLI script using the video ids as parameters and the results will be printed out to the command line:
```
youtube_transcript_api <first_video_id> <second_video_id> ...
```
The CLI also gives you the option to provide a list of preferred languages:
```
youtube_transcript_api <first_video_id> <second_video_id> ... --languages de en
```

If you would prefer to write it into a file or pipe it into another application, you can also output the results as json using the following line:

If a video's ID starts with a hyphen you'll have to mask the hyphen using `\` to prevent the CLI from mistaking it for a argument name. For example to get the transcript for the video with the ID `-abc123` run:
```
youtube_transcript_api "\-abc123"
```
## Proxy
You can specify a https/http proxy, which will be used during the requests to YouTube:
```python
from youtube_transcript_api import YouTubeTranscriptApi
YouTubeTranscriptApi.get_transcript(video_id, proxies={"http": "http://user:pass@domain:port", "https": "https://user:pass@domain:port"})
```
As the `proxies` dict is passed on to the `requests.get(...)` call, it follows the [format used by the requests library](http://docs.python-requests.org/en/master/user/advanced/#proxies).
Using the CLI:
```
youtube_transcript_api <first_video_id> <second_video_id> --http-proxy http://user:pass@domain:port --https-proxy https://user:pass@domain:port

Some videos are age restricted, so this module won't be able to access those videos without some sort of authentication. To do this, you will need to have access to the desired video in a browser. Then, you will need to download that pages cookies into a text file. You can use the Chrome extension [cookies.txt](https://chrome.google.com/webstore/detail/cookiestxt/njabckikapfpffapmjgojcnbfjonfjfg?hl=en) or the Firefox extension [cookies.txt](https://addons.mozilla.org/en-US/firefox/addon/cookies-txt/).
Once you have that, you can use it with the module to access age-restricted videos' captions like so.

## Warning
This code uses an undocumented part of the YouTube API, which is called by the YouTube web-client. So there is no guarantee that it won't stop working tomorrow, if they change how things work. I will however do my best to make things working again as soon as possible if that happens. So if it stops working, let me know!
