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.
- Remove useless concatenation on the downloader path;
- Remove unneeded public test modifier;
- Update license header;
- Specify the service class tested instead of the generic class.
- Switch to the new domain used by YouTube for search suggestions,
suggestqueries-clients6.youtube.com, and add the xhr query parameter with the
t value, to allow getting responses without requiring trim;
- Use the Java 8 Stream API to collect search suggestions and improve invalid
response detection by checking whether the content type of the response
returned is JSON;
- Move the licence header at the top of the file.
When a description is missing, no description should be returned, even the ones
indicating there is no description. This behavior is represented by a null
return instead.
Also update PeertubeAccountExtractorTest to reflect these changes.
The tested comment has been removed, so it couldn't be found in the comments
list.
This comment has been replaced by a new one from the current comments of the
video.
Also, in the parent class PeertubeCommentsExtractorTest, final has been used as
much as possible and for-each loops of lists have been replaced by their
forEach method or the Stream API, in order to simplify code.
As the "No views" string is returned in the case there is no view on a video, a
number cannot be parsed in this case, so -1 was returned.
This string is now detected in all methods to get the view count of a stream.
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).
As like count is now returned by the extractor, we need to assert a positive
minimum like count, which is close to the actual value, in order to avoid test
failures due to lower like counts than the ones excepted.
- Remove unused imports;
- Replace wildcard imports by single class imports;
- Suppress "HTTP links are not secured" warnings from IDEA IDEs;
- Replace removed video jZViOEv90dI by an existing video, 9Dpqou5cI08 (the
corresponding test has been of course renamed).
- 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.
