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.
This IllegalStateException, almost not reproducible, indicates that another SimpleCache instance uses the cache folder, which was so trying to be created at least twice.
Moving the SimpleCache creation in PlayerDataSource should avoid this exception.
The VideoDetailFragment will now get video streams dynamically instead of storing them as a field, so the good codec can be chosen by ListHelper.
To select a stream to play, user has now to select the quality in the list of available qualities and then press the new OK button in the alert dialog.
Detailed changes:
- External players:
- Add a message instruction about stream selection;
- Add a message when there is no stream available for external players;
- Return now HLS, DASH and SmoothStreaming URL contents, in addition to progressive HTTP ones.
- Player:
- Support DASH, HLS and SmoothStreaming streams for videos, whether they are content URLs or the manifests themselves, in addition to progressive HTTP ones;
- Use a custom HttpDataSource to play YouTube contents, based of ExoPlayer's default one, which allows better spoofing of official clients (custom user-agent and headers (depending of the client used), use of range and rn (set dynamically by the DataSource) parameters);
- Fetch YouTube progressive contents as DASH streams, like official clients, support fully playback of livestreams which have ended recently and OTF streams;
- Use ExoPlayer's default retries count for contents on non-fatal errors (instead of Integer.MAX_VALUE for non-live contents and 5 for live contents).
- Download dialog:
- Add message about support of progressive HTTP streams only for downloading;
- Remove several duplicated code and update relevant usages;
- Support downloading of contents with an unknown media format.
- ListHelper:
- Catch NumberFormatException when trying to compare two video streams between them.
- Tests:
- Update ListHelperTest and StreamItemAdapterTest to fix breaking changes in the extractor.
- Other places:
- Fixes deprecation of changes made in the extractor;
- Improve some code related to the files changed.
- Issues fixed and/or improved with the changes:
- Seeking of PeerTube HLS streams (the duration shown was the one from the stream duration and not the one parsed, incomplete because HLS streams are fragmented MP4s with multiple sidx boxes, for which seeking is not supported by ExoPlayer) (the app now uses the HLS manifest returned for each quality, in the master playlist (not fetched and computed by the extractor));
- Crash when loading PeerTube streams with a separated audio;
- Lack of some streams on some YouTube videos (OTF streams);
- Loading times of YouTube streams, after a quality change or a playback start;
- View count of YouTube ended livestreams interpreted as watching count (this type of streams is not interpreted anymore as livestreams);
- Watchable time of YouTube ended livestreams;
- Playback of SoundCloud HLS-only tracks (which cannot be downloaded anymore because the workaround which was used is being removed by SoundCloud, so it has been removed from the extractor).
These previews will be only available for images cached in the cache used by Picasso.
The Bitmap of the content is compressed in JPEG 90 and saved inside the application cache folder under the name android_share_sheet_image_preview.jpg.
The current image will be, of course, always overwritten by the next one and cleared when the application cache is cleared.
