In the new data model currently A/B tested or deployed, the like count button
data is the same, but its path has been changed.
The extraction of the like count has been also improved, by using the multiple
accessibility data available instead of the only one which was used before.
This accessibility data has been also deprioritized, because it is language
dependent when there is no view.
Like count is always known, even for age-restricted videos, so returning -1 if
the like count extraction fails on this type of videos is not needed and hides
an extraction error: that's the reason why this return has been removed and the
exception will always be thrown, even if a video is age-restricted.
YoutubeThrottlingDecrypter is now a non-instantiable final class and non-static
attributes have been removed.
The static attributes of this class have been renamed, in order to respect the
naming specification used.
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) 🥳
If YouTube detect that requests come from a third party client, they may
replace the real player response by another one of a video saying that this
content is not available on this app and to watch it on the latest version of
YouTube. We can detect this by checking whether the video ID of the player
response returned is the same as the one requested by the extractor.
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.
This will prevent any future extractor break due to decryption failure, like it was excepted to be the case before.
Some documentation about the throttling decryption has been also improved.
