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.
The test added in YoutubeDashManifestCreator uses a video of the Creative Commons channel, licenced under the Creative Commons Attribution licence (reuse allowed).
Also remove public keywords of tests in UtilsTest, as suggested by SonarLint, because they are not needed with Junit 5.
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)
Mixes seems to be not given by YouTube anymore if you use a PENDING consent cookie value.
As mocks needs to updated, the test is always failing because of this change.
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.
In order to use still use mocks with the generation of random strings in player requests, we need to use YoutubeParsingHelper.setSeedForVideoTests() method in every stream test.
The iOS client is only enabled for livestreams and the Android client is now only enabled for videos, both by default.
A way to force, or not, the fetch of both clients have been added with two new static methods in YoutubeStreamExtractor.
This is done by fetching https://www.youtube.com/sw.js for YouTube and https://music.youtube.com/sw.js for YouTube Music.
Two new methods in Utils class have been added which allow to try to get a match of regular expressions in a string array, or a Pattern array, on a content, on a specific index or 0.
Also some code refactoring has been made in this class.
The cpn param, aka the content playback nonce param, is a parameter sent by YouTube web client in videoplayback requests, and for some of them, in the player request body. This PR adds it everywhere.
For the desktop/WEB client, some params were missing from the playbackContext object, which seemed (or not) to make YouTube throttle streams extracted from the WEB client. This PR adds them.
Fingerprinting on the WEB client basing on the client version used is not possible anymore, because the latest client version is extracted at the first time of a YouTube request on a session which require the extractor to fetch again the website (and this may come back the reCaptcha issues again unfortunately, but it seems there is no other way to get it).
For the Android client, the video id is now also sent as a query parameter, like a 12 characters string, in the t query parameter, in order to spoof better this client. Researches need to be done on this parameter, unique to each request, and how it is generated by clients.
This commit also fixes a small bug with the Android User-Agent string.
Some code improvements have been also made.
The boolean keyAndVersionExtracted in YoutubeParsingHelper was not set to false when resetting the client version and the key, which makes the extractor uses null on the next getting of the client version or the key if the clientVersion and the key were extracted before.
Also update client versions.
That is, basically where the overriding function was missing an annotation from the base method.
Also apply renaming of emptyDescription to EMPTY_DESCRIPTION
