Also update the mock of the next InnerTube endpoint response of the
YoutubeStreamExtractorDefaultTest.DescriptionTestUnboxing test class with an
attributedDescription instead of a regular description
This new layout doesn't provide author thumbnails and is completely different
for metadata, so the code to get them has been refactored.
The code of learning playlists video count check has been also removed, as it
seems to be not relevant anymore (the video count seems to be returned for
these playlists with both layouts).
Finally, unneeded overrides of subchannel methods, which don't apply to the
YouTube service, have been removed.
Using the player parameters used to get stories seems to fix the issue, which
affects currently only certain countries such as UK.
This is a workaround and should be fixed in a better way (by changing the
InnerTube additional client used for videos or finding what is now required in
Android player requests).
This new structure allow us to filter easily Trending shorts and Recently
trending sections.
On the previous one, this Recently trending section is now filtered, by
checking whether sections have a title, which isn't the case for normal trends
contrary to the other ones.
This makes that the extractor returns now only the real 50 "Now" YouTube
trends.
Elements inside arrays are now extracted dynamically instead of only the ones
of the first index, using Java 8's Stream API.
The getInitialPage() method of YoutubeTrendingExtractor can now throw a
ParsingException if no selected tab (corresponding to the one of the trends
type extracted) has been found.
Finally, the licence header has been moved to the top of the file and updated.
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.
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.
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.
The ANDROID client was only fetched for video contents, where it can be useful on ended/post livestreams, if the n parameter of the WEB client cannot be decrypted, to avoid throttling issues (because the WEB client was only used before for ended/post livestreams).
It also provides an exclusive 48kbps M4A audio format in the adaptiveFormats array of the JSON player response, like other mobile clients (which can be also extracted from the response of the DASH manifest URL returned into the WEB client player's response, but the DASH manifest is not used by the extractor).
A note about non-fatality of fetching or parsing issues of the ANDROID and IOS clients has been added.
These values were only set before for video streams.
A fallback for the audio channels count has been added, in order to prevent exceptions when generating DASH manifests of audio streams: the fallback value is 2, because most audio streams on YouTube have 2 audio channels.
