Change square bitmap transformation strategy: change the bitmap transformation strategy when a 1:1 aspect ratio is
enabled to not stretch the bitmap but rather crop it.
On Android 11/12, the way the whole thumbnail was used for the
notification icon was not ideal, however the setting to toggle a 1:1
(as it states in settings) resulted in distortions.
Fix this by simply cropping the bitmap.
Also update the 1:1 mode strings to remove mentions of scaling or
distortions, as those no longer apply.
A custom HlsPlaylistParserFactory cannot be used anymore to play HLS streams.
This needs to be replaced by a custom HlsDataSourceFactory, which returns a ByteArrayDataSource (where the bytes of this DataSource correspond to the bytes of the playlist string) and a specified DataSource for other request types.
This model has two limitations:
- if media requests are relative, the URI from which the manifest comes from (either the manifest URI (preferred) or the master URI (if applicable)) must be returned, otherwise the content will be not playable, as it will be an invalid URL, or it may be treat as something unexpected, for instance as a file for DefaultDataSources;
- if the playlist is a master playlist, endless loops should be encountered because the DataSources created for media playlists will use the master playlist response instead of fetching the corresponding playlist. With the current model of HlsDataSourceFactory, there is no possibility to distinguish the playlist type or the URI that is requested.
If ExoPlayer provides a way to create HlsMediaSources with an HlsPlaylist in the future, it should be used instead of this solution.
This ensures to not remove streams from the StreamInfo lists themselves, and so to not have to create list copies.
The toast shown in RouterActivity, when there is no audio stream available for external players, is now shown, in the same case, when pressing the background button in VideoDetailFragment.
