YouTube now returns a Shorts tab for InteractiveTabbedHeader gaming channels,
which contains Shorts about the game of the topic channel but are not uploaded
on the game topic channel.
As this tab is already supported by the extractor, fetching a gaming topic
channel now returns a tab instead of none.
Channel name and channel URL of these Shorts needs to be set to null in a
separate commit, as Shorts on this tab do not have the topic channel as their
uploader.
The API keys are not used anymore by official clients in almost all cases
(still used by the Android app until it gets a configuration) for all requests
we made.
Clients and device OS versions have been bumped to their latest stable version
known.
Methods and fields related to API keys have been renamed or deleted if they're
no longer relevant.
YouTube provides that meta info panel when users search for really sensitive content like suicide (e.g. "blue whale").
It contains:
- an encouragement as title (e.g. "We are with you")
- a phone number as action
- details about how to call the phone number (e.g. availability)
- an url pointing to the website of an association
Also add a test that just checks if a meta info is properly extracted
This test only tests that search results are returned, when no content filters
are provided and crisis resources blocking search results should be returned.
Searches with blocking crisis resources and content filters should work too, as
the bypass has been implemented for them.
As search parameters to bypass crisis resources blocking search results have
been implemented, they need to be added to search tests, in order to pass
them.
The subscriber count is now lower than the expected count as some people
unsubscribed to the Sports system channel. The expected count has been so
lowered.
YouTube doesn't return anymore a suggestion for the query "algorythm", but does
for the query "on board ing" ("on boarding"). This search query is now used and
had to be URL-encoded.
URL encoding in the complete YoutubeSearchExtractorTest test class uses now
extractor's Util class instead of Java's URLDecoder class directly.
YouTube is rolling out or A/B testing a new date format returned inside player
responses, which are precise to the second instead of the day.
This commit makes the StreamExtractor tests use these more precise dates.
This commit fixes the testRelatedItems test method by:
- accepting consent in the test class, in order to extract mixes in
recommendations;
- removing assertion of a music mix inside the recommendations, as YouTube
doesn't seem to return such mixes anymore, at least for the video used in the
test class.
Replace the video used in this test class with another one publicly available
and update the corresponding expected test values.
The test class's mocks will be updated in a different commit.
- Change CarouselHeader test channel to Sports system one, as the Coachella one
doesn't return this channel header anymore;
- Fix InteractiveTabbedHeader test by checking whether the test's channel
description is not empty instead of containing some words, as it is changing
frequently.
Video's title and tags have been changed by its uploader, so they have to be
updated.
Also make some package-private constants private, as they are not used outside
of the class, and remove unneeded test overrides.
This query parameter for which its value is set to false was not added to two
requests made in test classes of YoutubeMixPlaylistExtractorTest.
Also remove an unneeded ParsingException exception throwing declaration in a
test method.
This commit is introducing breaking changes.
For clients, everything is managed in a new class called
YoutubeJavaScriptPlayerManager:
- caching JavaScript base player code and its extracted code (functions and
variables);
- getting player signature timestamp;
- getting deobfuscated signatures of streaming URLs;
- getting streaming URLs with a throttling parameter deobfuscated, if
applicable.
The class delegates the extraction parts to external package-private classes:
- YoutubeJavaScriptExtractor, to extract and download YouTube's JavaScript base
player code: it always already present before and has been edited to mainly
remove the previous caching system and made it package-private;
- YoutubeSignatureUtils, for player signature timestamp and signature
deobfuscation function of streaming URLs, added in a recent commit;
- YoutubeThrottlingParameterUtils, which was originally
YoutubeThrottlingDecrypter, for throttling parameter of streaming URLs
deobfuscation function and checking whether this parameter is in a streaming
URL.
YoutubeJavaScriptPlayerManager caches and then runs the extracted code if it
has been executed successfully. The cache system of throttling parameters
deobfuscated values has been kept, its size can be get using the
getThrottlingParametersCacheSize method and can be cleared independently using
the clearThrottlingParametersCache method.
If an exception occurs during the extraction or the parsing of a function
property which is not related to JavaScript base player code fetching, it is
stored until caches are cleared, making subsequent failing extraction calls of
the requested function or property faster and consuming less resources, as the
result should be the same until the base player code changes.
All caches can be reset using the clearAllCaches method of
YoutubeJavaScriptPlayerManager.
Classes using JavaScript base player code and utilities directly (in the code
and its tests) have been also updated in this commit.
Also remove some public test methods modifiers, add missing Test annotations on
old Junit 4 tests (and update them if needed), and use final in some places
where it was possible.
BandcampChannelExtractorTest.testLength has been removed as the test is always
true.
This method, testImages(Collection<Image>), will use first the default image
collection test in DefaultTests and then will check that each image URL
contains f4.bcbits.com/img and ends with .jpg or .png.
To do so, a new non-instantiable final class has been added: BandcampTestUtils.
Also remove some public test methods modifiers, add missing Test annotations on
old Junit 4 tests (and update them if needed), and use final in some places
where it was possible.
