The video "Makani’s first commercial-scale energy kite" (video ID:
An8vtD1FDqs), which has this behavior, is used for the new test,
NoVisualMetadataVideoTest, added in YoutubeStreamExtractorDefaultTest.
Tests of elements who throw an exception in this case (subscriber count, like
count, uploader avatar URL) test if the ParsingException exception is thrown by
YoutubeStreamExtractor.
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
The video count is now returned for this playlist, so it isn't unknown.
The testStreamCount method of this test class asserts now that the stream count
is greater than 40.
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.
