The signature timestamp is used as a number by HTML5 clients, so it should be
used in the same way by the extractor too instead of being a string.
As the timestamp doesn't seem to exceed 5 digits, an integer is used to store
its value.
Unmodifiable lists of Images are returned, parsed from a given YouTube
"thumbnails" JSON array.
These methods will be used in all YouTube extractors and InfoItems, as the
structures between content types (videos, channels, playlists, ...) are common.
Support of tags and videos, shorts, live, playlists and channels tabs has been
added for non-age restricted channels.
Age-restricted channels are now also supported and always returned the videos,
shorts and live tabs, accessible using system playlists. These tabs are the
only ones which can be accessed using YouTube's desktop website without being
logged-in.
The videos channel tab parameter has been updated to the one used by the
desktop website and when a channel extraction is fetched, this tab is returned
in the list of tabs as a cached one in the corresponding link handler.
Visitor data support per request has been added, as a valid visitor data is
required to fetch continuations with contents on the shorts tab. It is only
used in this case to enhance privacy.
A dedicated shorts UI elements (reelItemRenderers) extractor has been added,
YoutubeReelInfoItemExtractor. These elements do not provide the exact view
count, any uploader info (name, URL, avatar, verified status) and the upload
date.
All service's LinkHandlers are now using the singleton pattern and some code
has been also improved on the files changed.

webCommandMetadata object is contained inside a commandMetadata one, so it is
not accessible from the root of the navigationEndpoint object.
The corresponding statement has been moved at the bottom of the specific
endpoints parsing, as the webCommandMetadata object is present almost
everywhere, otherwise URLs of some endpoints would have be changed, such as
uploader URLs (from channel IDs to handles).
As no ParsingException is now thrown by getUrlFromNavigationEndpoint, and so by
getTextFromObject, getUrlFromObject and getTextAtKey, the methods which were
catching ParsingExceptions thrown by these methods had to be updated.
URLs got in the HTML version of getTextFromObject are now escaped properly to
provide valid HTML to clients. This has been also done for attribute
descriptions, with the description text for this type of descriptions.
As YouTube descriptions are in HTML format (except for the fallback on the JSON
player response, which is plain text and only happens when there is no visual
metadata or a breaking change), all URLs returned are escaped, so tests which
are testing presence of URLs with escaped characters had to be updated (it was
only the case for YoutubeStreamExtractorDefaultTest.DescriptionTestUnboxing).
This header was not sent partially before and was added and guessed by OkHttp. This can create issues when using other HTTP clients than OkHttp, such as Cronet.
Some code in the modified classes has been improved and / or deduplicated, and usages of the UTF_8 constant of the Utils class has been replaced by StandardCharsets.UTF_8 where possible.
Note that this header has been not added in except in YoutubeDashManifestCreatorsUtils, as an empty body is sent in the POST requests made by this class.
Also update the mock of the next InnerTube endpoint response of the
YoutubeStreamExtractorDefaultTest.DescriptionTestUnboxing test class with an
attributedDescription instead of a regular description
Added option to choose if you want to consent or not - currently this is done by a static variable in ``YoutubeParsingHelper`` - may not be the best long-term solution but for now the tests work again (in EU countries) 🥳
Additional parameters have been added to the player requests of ANDROID and IOS
clients:
- for both clients: osName and osVersion: their respective values are:
- for the ANDROID one: Android and 12;
- for the IOS one: iOS and 15.6.0.19G71.
- for the ANDROID client: androidTargetSdkVersion, with the Android SDK version
corresponding to the Android version used in the player requests of this
client. This parameter is now required with this client to be sure to get a
correct player response, otherwise, the one of a video saying that this
content is not available in this app and to watch it with the latest version
of YouTube can be returned instead;
- for the IOS client: deviceMake, with Apple as its value.
The iOS version sent in the IOS client player requests has been also updated to
the version 15.6 of the OS.
Finally, a comment about the requirement to use the signature timestamp from
the player JavaScript base file for HTML5 player requests on videos with
obfuscated URLs has been added and replaces a previous one which may be not
true.
Common code in WEB client version HTML extraction has been deduplicated, usage of the Java 8 Stream API has been made and initial data fallback has been used as a last resort.
This means that the client version extraction from regexes will be used before this fallback, as it doesn't contain the full client version.
This can be used as a way to fingerprint the extractor, even if it seems to be not the case.
Extract post live DVR streams as post live streams instead of live streams.
A new class has been in order to improve code: ItagInfo, which stores an itag, the content (URL) extracted and if its an URL or not.
A functional interface has been added in order to abstract the stream building: StreamBuilderHelper.
Also add the cver parameter added by the desktop web client on the corresponding streams (a new method has been added in YoutubeParsingHelper to check this and another for Android streams).
Some code in these classes has been also refactored/improved/optimized.
Google returns now the consent page of YouTube for YouTube Music in EU, which can be also avoided by adding the ucbcb parameter to the URL with the value 1 ("?ucbcb=1").
Use the TV embedded client technique to get streams of embeddable age-restricted videos.
This client doesn't provide the playerMicroFormatRenderer object in the player response, but it is still returned on the WEB player response, even for unavailable (but non-private) contents, so we need now to store it, as we are replacing the player response from the WEB client by the TV embedded one.
Otherwise, some metadata such as the unlisted property, category, the uploadDate and the publishDate properties.
The outdated code for these contents has been removed.
Add the racyCheckOk and contentCheckOk to player and next requests to the InnerTube API.
The first doesn't seem to make any difference when used anonymously, but the second one is needed to get streams of contents with a warning before they can be played.
Also apply some requested changes, fixes and improvements in YoutubeParsingHelper and YoutubeStreamExtractor.
Also move the iPhone device machine id to a constant, explain how it is used and move the licence in the header of the file, and fix missing imports in YoutubeStreamExtractor (due to a rebase issue).
InnerTube responses return pretty printed responses, which increase responses' size for nothing.
By using the prettyPrint parameter on requests and setting its value to false, responses are not pretty printed anymore, which reduces responses size, and so data transfer and processing times.
This usage has been recently deployed by YouTube on their websites.
