* youtube-dl tries to remove some superfluous punctuations from filenames. While this can sometimes be helpfull, it is often undesirable. So yt-dlp tries to keep the fields in the filenames as close to their original values as possible. You can use `--compat-options filename-sanitization` to revert to youtube-dl's behavior
For ease of use, a few more compat options are available:
+
* `--compat-options all`: Use all compat options
* `--compat-options youtube-dl`: Same as `--compat-options all,-multistreams`
* `--compat-options youtube-dlc`: Same as `--compat-options all,-no-live-chat,-no-youtube-channel-redirect`

`%XDG_CONFIG_HOME%` defaults to `~/.config` if undefined. On windows, `%APPDATA%` generally points to `C:\Users\<user name>\AppData\Roaming` and `~` points to `%HOME%` if present, `%USERPROFILE%` (generally `C:\Users\<user name>`), or `%HOMEDRIVE%%HOMEPATH%`
+
1. **System Configuration**: `/etc/yt-dlp.conf`
For example, with the following configuration file yt-dlp will always extract the audio, not copy the mtime, use a proxy and save all videos under `YouTube` directory in your home directory:
It may however also contain special sequences that will be replaced when downloading each video. The special sequences may be formatted according to [Python string formatting operations](https://docs.python.org/3/library/stdtypes.html#printf-style-string-formatting). For example, `%(NAME)s` or `%(NAME)05d`. To clarify, that is a percent symbol followed by a name in parentheses, followed by formatting operations.
The field names themselves (the part inside the parenthesis) can also have some special formatting:
+
1. **Object traversal**: The dictionaries and lists available in metadata can be traversed by using a `.` (dot) separator. You can also do python slicing using `:`. Eg: `%(tags.0)s`, `%(subtitles.en.-1.ext)s`, `%(id.3:7:-1)s`, `%(formats.:.format_id)s`. `%()s` refers to the entire infodict. Note that all the fields that become available using this method are not listed below. Use `-j` to see such fields
1. **Addition**: Addition and subtraction of numeric fields can be done using `+` and `-` respectively. Eg: `%(playlist_index+10)03d`, `%(n_entries+1-playlist_index)d`
Note that any field created by this can be used in the [output template](#output-template) and will also affect the media file's metadata added when using `--add-metadata`.
This option also has a few special uses:
+
* You can download an additional URL based on the metadata of the currently downloaded video. To do this, set the field `additional_urls` to the URL that you want to download. Eg: `--parse-metadata "description:(?P<additional_urls>https?://www\.vimeo\.com/\d+)` will download the first vimeo video found in the description
+
* You can use this to change the metadata that is embedded in the media file. To do this, set the value of the corresponding field with a `meta_` prefix. For example, any value you set to `meta_description` field will be added to the `description` field in the file. For example, you can use this to set a different "description" and "synopsis". To modify the metadata of individual streams, use the `meta<n>_` prefix (Eg: `meta1_language`). Any value set to the `meta_` field will overwrite all default values.
**Note**: Metadata modification happens before format selection, post-extraction and other post-processing operations. Some fields may be added or changed during these steps, overriding your changes.
```python
from yt_dlp import YoutubeDL
-ydl_opts = {'format': 'bestaudio'}
-with YoutubeDL(ydl_opts) as ydl:
- ydl.download(['https://www.youtube.com/watch?v=BaW_jenozKc'])
+URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
+with YoutubeDL() as ydl:
+ ydl.download(URLS)
```
Most likely, you'll want to use various options. For a list of options available, have a look at [`yt_dlp/YoutubeDL.py`](yt_dlp/YoutubeDL.py#L181).
-Here's a more complete example demonstrating various functionality:
+**Tip**: If you are porting your code from youtube-dl to yt-dlp, one important point to look out for is that we do not guarantee the return value of `YoutubeDL.extract_info` to be json serializable, or even be a dictionary. It will be dictionary-like, but if you want to ensure it is a serializable dictionary, pass it through `YoutubeDL.sanitize_info` as shown in the example above

+## Embedding examples
+
+### Extracting information
```python
import json
import yt_dlp
+URL = 'https://www.youtube.com/watch?v=BaW_jenozKc'
+
+# ℹ️ See help(yt_dlp.YoutubeDL) for a list of available options and public functions
+ydl_opts = {}
+with yt_dlp.YoutubeDL(ydl_opts) as ydl:
+ info = ydl.extract_info(URL, download=False)
+
+ # ℹ️ ydl.sanitize_info makes the info json-serializable
+ print(json.dumps(ydl.sanitize_info(info)))
+```
+### Download from info-json
+
+```python
+import yt_dlp
+
+INFO_FILE = 'path/to/video.info.json'
+
+with yt_dlp.YoutubeDL() as ydl:
+ error_code = ydl.download_with_info_file(INFO_FILE)
+
+print('Some videos failed to download' if error_code
+ else 'All videos successfully downloaded')
+```
+
+### Extract audio
+
+```python
+import yt_dlp
+
+URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
+
+ydl_opts = {
+ 'format': 'm4a/bestaudio/best'
+ # ℹ️ See help(yt_dlp.postprocessor) for a list of available Postprocessors and their arguments
+ 'postprocessors': [{ # Extract audio using ffmpeg

+ 'preferredcodec': 'm4a',
+ }]
+}
+
+with yt_dlp.YoutubeDL(ydl_opts) as ydl:
+ error_code = ydl.download(URLS)
+```
+### Adding logger and progress hook
+
+```python
+import yt_dlp
+
+URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
class MyLogger:
def debug(self, msg):
print(msg)
-# ℹ️ See the docstring of yt_dlp.postprocessor.common.PostProcessor

+ 'progress_hooks': [my_hook],
+}
+
+with yt_dlp.YoutubeDL(ydl_opts) as ydl:

return [], info
-# ℹ️ See "progress_hooks" in the docstring of yt_dlp.YoutubeDL
-def my_hook(d):

- print('Done downloading, now converting ...')
+with yt_dlp.YoutubeDL() as ydl:
+ ydl.add_post_processor(MyCustomPP())
+ ydl.download(URLS)
+```
+### Use a custom format selector
+
+```python
+import yt_dlp
+
+URL = ['https://www.youtube.com/watch?v=BaW_jenozKc']
+
def format_selector(ctx):
""" Select the best video and the best audio that won't result in an mkv.

# formats are already sorted worst to best
formats = ctx.get('formats')[::-1]
best_audio = next(f for f in formats if (
f['acodec'] != 'none' and f['vcodec'] == 'none' and f['ext'] == audio_ext))
+ # These are the minimum required fields for a merged format
yield {

'format_id': f'{best_video["format_id"]}+{best_audio["format_id"]}',
'ext': best_video['ext'],
'requested_formats': [best_video, best_audio],
}
-# ℹ️ See docstring of yt_dlp.YoutubeDL for a description of the options

- }],
- 'logger': MyLogger(),
- 'progress_hooks': [my_hook],
- # Add custom headers
- 'http_headers': {'Referer': 'https://www.google.com'}
