Getting audio tracks locales by parsing their ID or their label, should not be
done by clients, but by the extractor.
This commit adds the ability to store the Locale of an AudioStream, which is
used to compare similar AudioStreams (in the equalStats method).
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).
- Move license header at the top;
- Use an unmodifiable set for the subpaths instead of a modifiable list;
- Add missing Nonnull and Nullable annotations;
- Improve exception messages.
The yt:channelId element doesn't provide the channel ID anymore and is empty,
like the id element, so we need now to extract it from the channel URL provided
in two elements: author -> uri and feed -> link.
Also avoid a NullPointerException in getUrl and getName methods.
- Return duration of video premieres;
- Add another non-localized method to determine whether a stream is a running
livestream;
- Return view count and upload date of videos in playlists;
- Store isPremiere result;
- Remove shorts workaround code, as it was only useful on channels and shorts
have been moved into a separated channel tab;
- Improve some other code.
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.
This header was not sent before and was added and guessed by OkHttp. This can create issues when using other HTTP clients than OkHttp, such as Cronet.
Also make use of StandardCharsets.UTF_8 when getting bytes of bodies instead of the platform default's charset, to make sure to prevent some encoding issues on some JVMs.
More non-channel paths have been also added to the excluded custom name paths,
documentation and exception messages have been improved and fixed in some
places, and the licence header of YoutubeChannelLinkHandlerFactory has been
moved to its beginning and updated.
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).
Use the same possible characters for variables everywhere, in order to avoid
potential future throttling parameter decryption function name parsing issues
related to the usage of other letter(s) than b.
- Quote the function name, as it may contain special regex symbols, such as
dollar;
- Support multiple lines;
- Use what looks like the end of the function for the end of the regex (this
part is inspired from yt-dlp throttling parameter decryption regex);
- Move the throttling function body regex into a private and static constant.
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.
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.
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.
SoundCloud is currently removing this workaround completely, so there is no need to keep it, because it impacts the loading time (a HLS playlist was downloaded and parsed).
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.
SoundCloud broke the workaround used to get a single file from HLS manifests for Opus manifests, but it still works for MP3 ones.
The code has been adapted to prevent an unneeded request (the one to the Opus HLS manifest) and the HLS delivery method is now used for SoundCloud MP3 and Opus streams, plus the progressive one (for tracks which have a progressive stream (MP3) and for the ones which doesn't have one, it is still used by trying to get a progressive stream, using the workaround).
Streams extraction has been also moved to Java 8 Stream's API and the relevant test has been also updated.
Move DASH manifests creation into a new subpackage of the YouTube package, dashmanifestcreators.
This subpackage contains:
- CreationException, exception extending Java's RuntimeException, thrown by manifest creators when something goes wrong;
- YoutubeDashManifestCreatorsUtils, class which contains all common methods and constants of all or a part of the manifest creators;
- a manifest creator has been added per delivery type of YouTube streams:
- YoutubeProgressiveDashManifestCreator, for progressive streams;
- YoutubeOtfDashManifestCreator, for OTF streams;
- YoutubePostLiveStreamDvrDashManifestCreator, for post-live DVR streams (which use the live delivery method).
Every DASH manifest creator has a getCache() static method, which returns the ManifestCreatorCache instance used to cache results.
DeliveryType has been also extracted from the YouTube DASH manifest creators part of the extractor and moved to the YouTube package.
YoutubeDashManifestCreatorTest has been updated and renamed to YoutubeDashManifestCreatorsTest, and YoutubeDashManifestCreator has been removed.
Finally, several documentation and exception messages fixes and improvements have been made.
This change allows to build DASH manifests using YoutubeDashManifestCreator with the real duration of streams and prevent potential cuts of the end of progressive streams, because the duration in YouTube's player response is in seconds and not milliseconds.
When moving opus-lo into a constant, opus-lo was renamed to opus_lo and was only used if no MP3 stream was available (which was not the case before the changes in BandcampRadioStreamExtractor related to the addition of the support of all delivery methods), so these changes removed the ability to get Opus streams of Bandcamp radios.
This commit reverts this unwanted change.
- Remove all of the methods used to access caches and replace them with three caches getters
- Rename caches to shorter and more meaningful names
- Remove redundant @throws tags that just say "if this method fails to do what it should do", which is obvious
This commits reverts a new behavior introduced in this branch, which only applied the decryption if needed on streams from the WEB client.
Also fix rebase issues and documentations style in YoutubeDashManifestCreator.
These methods don't need to be overriden, as they are not excepted to be used in collections.
Also improve the toString method of this class, which contains also now clearFactor and maximumSize attributes and for each operations.
This parameter is still used to get the initialization sequence of OTF and POST-live streams, but is not returned anymore in the manifests.
It has been removed in order to avoid fingerprinting based on the number sent (e.g. when starting to play a stream close to the end and using 123 as the request number where it should be 1) and should be added dynamically by clients in their requests.
The relevant test has been also updated.
Checkstyle issues in YoutubeDashManifestCreator have been fixed, and the changes in the resolution string returned for video streams in YoutubeStreamExtractor have been reverted, as they create issues on NewPipe right now.
To do so, a copy constructor has been added in the class.
This fixes, for instance, an issue in NewPipe, in which the ItagItem values where not the ones corresponsing to a stream but to another, when generating DASH manifests.
A new class has been added to do so: YoutubeDashManifestCreator.
It relies on a new class: ManifestCreatorCache, to cache the content, which relies on a new pair class named Pair.
Results are cached and there is a cache per delivery type, on which cache limit, clear factor, clearing and resetting can be applied to each cache and to all caches.
Look at code changes for more details.
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.
Some code in these classes has been also refactored/improved/optimized.
Also fix the extraction of PeerTube audio streams as video streams, which are now returned as audio streams.
These fields can be now replaced by a getter and a setter.
New fields have been added and will allow the creation of DASH manifests for OTF and ended livestreams. There are:
- contentLength;
- approxDurationMs;
- targetDurationSec;
- sampleRate;
- audioChannels.
DashMpdParser is only working with YouTube streams, as it uses the ItagItem class.
Also improve code and comments of StreamInfo (especially final use where possible).
Stream constructors are now private and streams can be constructed with new Builder classes per stream class. This change has been made to prevent creating and using several constructors in stream classes.
Some default cases have been also added in these Builder classes, so not everything has to be set, depending of the service and the content.
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").
* Fixed obvious sonar(lint) warnings
* Abstracted some code (get*Streams)
* Used some new lines to make code better readable
* Chopped down brace-jungle in some methods
* Use StandardCharset (Java 8 4tw)
