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.
This method, testImages(Collection<Image>), will use first the default image
collection test in DefaultTests and then will check that each image URL
contains the string yt.
The JavaDoc of the class has been also updated to reflect the changes made in
it (it is now more general).
Two new methods have been added in ExtractorAsserts to check if a collection is
empty:
- assertNotEmpty(String, Collection<?>), checking:
- the non nullity of the collection;
- its non emptiness (if that's not case, an exception will be thrown using
the provided message).
- assertNotEmpty(Collection<?>), calling assertNotEmpty(String, Collection<?>)
with null as the value of the string argument.
A new one has been added to this assertion class to check the contrary:
assertEmpty(Collection<?>), checking emptiness of the collection only if it is
not null.
Three new methods have been added in ExtractorAsserts as utility test methods
for image collections:
- assertContainsImageUrlInImageCollection(String, Collection<Image>), checking
that:
- the provided URL and image collection are not null;
- the image collection contains at least one image which has the provided
string value as its URL (which is a string) property.
- assertContainsOnlyEquivalentImages(Collection<Image>, Collection<Image>),
checking that:
- both collections are not null;
- they have the same size;
- each image of the first collection has its equivalent in the second one.
This means that the properties of an image in the first collection must be
equal in an image of the second one.
- assertNotOnlyContainsEquivalentImages(Collection<Image>, Collection<Image>),
checking that:
- both collections are not null;
- one of the following conditions is met:
- they have different sizes;
- an image of the first collection has not its equivalent in the second one.
This means that the properties of an image in the first collection must
be not equal in an image of the second one.
These methods will be used by services extractors tests (and default ones) to
test image collections.
This new method, defaultTestImageList(List<Image), will check that the image
list is not null.
For each image, it will test that its URL is secure and its height and width
are more than or equal to their relevant unknown constants in the Image class
(HEIGHT_UNKNOWN and WIDTH_UNKNOWN).
These three new methods, added in MediaCCCParsingHelper,
getImageListFromImageUrl(String), getThumbnailsFromStreamItem(JsonObject) and
getThumbnailsFromLiveStreamItem(JsonObject) (the last two are based on a common
method, getThumbnailsFromObject(JsonObject, String, String)), return an empty
list if the case no image URL could be extracted.
Images returned have their height and width unknown and a resolution level
depending on the image key of the JSON API response.
Bandcamp images work with image IDs, which provide different resolutions.
Images on Bandcamp are not always squares, and some IDs respect aspect ratios
where some others not.
The extractor will only use the ones which preserve aspect ratio and will not
provide original images, for performance and size purposes.
Because of this aspect ratio preservation constraint, only one dimension will
be known at a time.
The image IDs with their respective dimension used are:
- 10: 1200w;
- 101: 90h;
- 170: 422h;
- 171: 646h;
- 20: 1024w;
- 200: 420h;
- 201: 280h;
- 202: 140h;
- 204: 360h;
- 205: 240h;
- 206: 180h;
- 207: 120h;
- 43: 100h;
- 44: 200h.
(Where w represents the width of the image and h the height of the image)
Note that these dimensions are theoretical because if the image size is less
than the dimensions of the image ID, it will be not upscaled but kept to its
original size.
All these resolutions are stored in a private static list of ThumbnailSuffixes
in BandcampExtractorHelper, in which the methods to get mutliple images have
been added:
- getImagesFromImageUrl(String): public method to get images from an image URL;
- getImagesFromImageId(long, boolean): public method to get images from an
image ID;
- getImagesFromImageBaseUrl(String): private utility method to get images from
the static list of ThumbnailSuffixes from a given image base URL, containing
the path to the image, a "a" letter if it comes from an album, its ID and an
underscore.
Some existing methods have been also edited:
- the documentation of getImageUrl(long, boolean) has been changed to reflect
the Bandcamp images findings;
- getThumbnailUrlFromSearchResult has been renamed to
getImagesFromSearchResult, and a documentation has been added to this method.
The method replaceHttpWithHttps of the Utils class has been also used in
BandcampExtractorHelper instead of doing manually what the method does.
The default avatar picture was used when no profile picture was found, but it
was removed and split in multiple images.
Thumbnails' size is not known, as this data is not provided by the API.
This method, getThumbnailsFromPlaylistOrVideoItem, has been added in
PeertubeParsingHelper and returns the two image variants for playlists and
videos.
Four new static methods have been added in PeertubeParsingHelper to do so:
- two public methods to get the corresponding image type:
getAvatarsFromOwnerAccountOrVideoChannelObject(String, JsonObject) and
getBannersFromAccountOrVideoChannelObject(String, JsonObject);
- two private methods as helper methods: getImagesFromAvatarsOrBanners(String,
JsonObject, String, String) and getImagesFromAvatarOrBannerArray(String,
JsonArray).
These new public and static methods, added in SoundcloudParsingHelper,
getAllImagesFromArtworkOrAvatarUrl(String) and
getAllImagesFromVisualUrl(String) (which call a common private method,
getAllImagesFromImageUrlReturned(String, List<ImageSuffix>, List<Image>)),
return an unmodifiable list of JPEG images containing almost every image
resolution provided by SoundCloud except the original size and the tiny
resolution (for artworks and avatars, as the image size is 20x20 for artworks
and 18x18 for avatars, so very close to or equal to the t20x20 resolution):
- for artworks and avatars:
- mini: 16x16;
- t20x20: 20x20;
- small: 32x32;
- badge: 47x47;
- t50x50: 50x50;
- t60x60: 60x60;
- t67x67: 67x67;
- large: 100x100;
- t120x120: 120x120;
- t200x200: 200x200;
- t240x240: 240x240;
- t250x250: 250x250;
- t300x300: 300x300;
- t500x500: 500x500.
- for visuals/user banners:
- t1240x260: 1240x260;
- t2480x520: 2480x520.
Duplicated code in two methods of SoundcloudParsingHelper
(getUsersFromApi(ChannelInfoItemsCollector, String) and
getStreamsFromApi(StreamInfoItemsCollector, String, boolean)) has been merged
into one common private method, getNextPageUrlFromResponseObject(JsonObject).
Splitting YoutubeMusicSearchExtractor's InfoItemExtractors into separate
classes (YoutubeMusicSongOrVideoInfoItemExtractor,
YoutubeMusicAlbumOrPlaylistInfoItemExtractor and
YoutubeMusicArtistInfoItemExtractor) allows to simplify
YoutubeMusicSearchExtractor,improves reading and applying changes to InfoItems
(no more losing at least quarter of a line due to indentations).
These InfoItems, in which the image changes have been applied, don't extend the
YouTube ones anymore, as most methods were overridden and the few ones that are
not don't apply in YouTube Music items responses, so it was useless to extend
them.
The code of YoutubeMusicSearchExtractor have been also improved a bit.
Unmodifiable lists of Images are returned, parsed from a given YouTube
"thumbnails" JSON array.
These methods will be used in all YouTube extractors and InfoItems, as the
structures between content types (videos, channels, playlists, ...) are common.
The goal of this utility class is to simply store suffixes which need to be
appended to image URLs, in order to get images at the suffix resolution.
This class contains four properties: the suffix (as a string), the height,
the width (as integers) and the estimated resolution level of the image
corresponding to the one represented by the suffix.
Objects of this serializable class contains four properties: a URL (as a
string), a width, a height (represented as integers) and an estimated
resolution level, which can be constructed from a given height.
Possible resolution levels are:
- UNKNOWN: for unknown heights or heights <= 0;
- LOW: for heights > 0 & < 175;
- MEDIUM: for heights >= 175 & < 720;
- HIGH: for heights >= 720.
Getters of these properties are available and the constructor needs these four
properties.
The addition of this support required to turn the isCarouselHeader boolean into
an enum containing all supported channel headers named HeaderType.
Also assert that the page has been fetched where needed to avoid
NullPointerExceptions when the channel page has been not fetched and remove the
getChannelHeaderJson method in YoutubeChannelExtractor, method for which its
code has been moved to its sole usage after the new headers support changes.
The non-null assertion was made on the exception message instead of the string
to check, causing a NullPointerException if the string to check was null.
Note that this introduces a "Raw use of parameterized class 'InfoItemsPage'" warning, but it can be ignored since the type missing would be <InfoItem>, and StreamInfoItem extends InfoItem
Only the first content filter of the ListLinkHandler instances provided is
used when collecting all channel tabs of the ListLinkHandler list, as channel
tabs implementations only use one content filter per ListLinkHandler instance.

These changes should help to detect tests as tests, when running a subset of
tests or all tests.
They should be also implemented in these interfaces' implementations (new and
existing ones).

Support of tags and videos, shorts, live, playlists and channels tabs has been
added for non-age restricted channels.
Age-restricted channels are now also supported and always returned the videos,
shorts and live tabs, accessible using system playlists. These tabs are the
only ones which can be accessed using YouTube's desktop website without being
logged-in.
The videos channel tab parameter has been updated to the one used by the
desktop website and when a channel extraction is fetched, this tab is returned
in the list of tabs as a cached one in the corresponding link handler.
Visitor data support per request has been added, as a valid visitor data is
required to fetch continuations with contents on the shorts tab. It is only
used in this case to enhance privacy.
A dedicated shorts UI elements (reelItemRenderers) extractor has been added,
YoutubeReelInfoItemExtractor. These elements do not provide the exact view
count, any uploader info (name, URL, avatar, verified status) and the upload
date.
All service's LinkHandlers are now using the singleton pattern and some code
has been also improved on the files changed.

This new ListLinkHandler, ReadyChannelTabListLinkHandler, should help saving
clients data, energy and time by helping to reduce duplicate requests.

This change advertise to clients that channel tabs' link handler factories can
return an UnsupportedOperationException when a tab provided to them is
unsupported.
This commit introduces the following breaking changes:
- Three new classes have been added:
- ChannelTabExtractor, class extending ListExtractor<InfoItem>, which
extracts InfoItems from a channel tab;
- ChannelTabInfo extending ListInfo<InfoItem>, which extracts InfoItems from
a ChannelTabExtractor and returns them as a ChannelTabInfo;
- ChannelTabs, an immutable class containing all supported channel tabs.
- StreamingService implementations must implement new methods returning a
channel tab LinkHandlerFactory (getChannelTabsLHFactory) and a
ChannelTabExtractor (getChannelTabExtractor);
- ChannelExtractor inherits Extractor instead of ListExtractor<StreamInfoItem>
and ChannelInfo inherits Info instead of ListInfo<StreamInfoItem>;
- ChannelExtractor and ChannelInfo have now getters and/or setters of tabs.

- Enhance documentation;
- Fix the regular expression fallback on HTML embed watch page;
- Use HTML scripts tag search first instead of the regular expression approach,
now used as a last resort;
- Compile regular expressions only once, in order to improve the performance of
subsequent extraction calls when clearing the cache;
- Provide original exceptions when fetching or parsing pages on which the base
JavaScript's player could be found failed, allowing clients to detect network
errors when they are the cause of the failures for instance;
- Remove delegate method which was not taking a video ID and hardcoding one, as
we can provide the video ID in all cases or do not provide a video ID at worse;
- Rename and make extraction methods package-private, as they are not intended
to be used publicly.
These breaking internal changes have been applied where needed, in
YoutubeJavaScriptExtractorTest and YoutubeStreamExtractor (in which an unneeded
initStsFromPlayerJsIfNeeded call have been removed).
- Fix testCheckAudioStreams test of
YoutubeStreamExtractorDefaultTest.AudioTrackLanguage test class, by updating
the excepted audio track name test to use the updated English audio track name
(audio track type info has been added on the video tested);
- Fix YoutubeStreamExtractorDefaultTest.PublicBroadcasterTest test class by
using a different video from a French and German public broadcast channel, as
the channel Dinge Erklärt – Kurzgesagt is not affiliated with a public
broadcast channel anymore;
- Fix YoutubeStreamExtractorLivestreamTest test class, by updating the excepted
name of the livestream to the current one.
These parameters are the only ones currently known to bypass 403 HTTP issues
related to failure of passing Android client integrity checks, as the ones of
stories (and the base of the shorts ones) do not work anymore, which may be
related to end of this format on the service.
