* When `--embed-subs` and `--write-subs` are used together, the subtitles are written to disk and also embedded in the media file. You can use just `--embed-subs` to embed the subs and automatically delete the separate file. See [#630 (comment)](https://github.com/yt-dlp/yt-dlp/issues/630#issuecomment-893659460) for more info. `--compat-options no-keep-subs` can be used to revert this
* `certifi` will be used for SSL root certificates, if installed. If you want to use system certificates (e.g. self-signed), use `--compat-options no-certifi`
* yt-dlp's sanitization of invalid characters in filenames is different/smarter than in youtube-dl. You can use `--compat-options filename-sanitization` to revert to youtube-dl's behavior
+* yt-dlp tries to parse the external downloader outputs into the standard progress output if possible (Currently implemented: `aria2c`). You can use `--compat-options no-external-downloader-progress` to get the downloader output as-is
For ease of use, a few more compat options are available:
* `--compat-options all`: Use all compat options (Do NOT use)
* `--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`
+* `--compat-options 2021`: Same as `--compat-options 2022,no-certifi,filename-sanitization,no-youtube-prefer-utc-upload-date`
+* `--compat-options 2022`: Same as `--compat-options no-external-downloader-progress`. Use this to enable all future compat options

-All public classes with a name ending in `IE` are imported from each file. This respects underscore prefix (e.g. `_MyBasePluginIE` is private) and `__all__`. Modules can similarly be excluded by prefixing the module name with an underscore (e.g. `_myplugin.py`)
+All public classes with a name ending in `IE`/`PP` are imported from each file for extractors and postprocessors repectively. This respects underscore prefix (e.g. `_MyBasePluginIE` is private) and `__all__`. Modules can similarly be excluded by prefixing the module name with an underscore (e.g. `_myplugin.py`)
+
+To replace an existing extractor with a subclass of one, set the `plugin_name` class keyword argument (e.g. `MyPluginIE(ABuiltInIE, plugin_name='myplugin')` will replace `ABuiltInIE` with `MyPluginIE`).
+Due to the mechanics behind this, you should exclude the subclass extractor from being imported separately by making it private using one of the methods described above.
