MediaPlayer.PlayerCallback

public void onError(
    @NonNull MediaPlayer mp,
    @NonNull MediaItem item,
    int what,
    int extra
)

Called to indicate an error.

public void onInfo(@NonNull MediaPlayer mp, @NonNull MediaItem item, int what, int extra)

Called to indicate an info or a warning.

public void onMediaTimeDiscontinuity(
    @NonNull MediaPlayer mp,
    @NonNull MediaItem item,
    @NonNull MediaTimestamp timestamp
)

Called when a discontinuity in the normal progression of the media time is detected.

The "normal progression" of media time is defined as the expected increase of the playback position when playing media, relative to the playback speed (for instance every second, media time increases by two seconds when playing at 2x). Discontinuities are encountered in the following cases:

• when the player is starved for data and cannot play anymore
• when the player encounters a playback error
• when the a seek operation starts, and when it's completed
• when the playback speed changes
• when the playback state changes
• when the player is reset

public void onTimedMetaDataAvailable(
    @NonNull MediaPlayer mp,
    @NonNull MediaItem item,
    @NonNull TimedMetaData data
)

Called to indicate available timed metadata

This method will be called as timed metadata is extracted from the media, in the same order as it occurs in the media. The timing of this event is not controlled by the associated timestamp.

Currently only HTTP live streaming data URI's embedded with timed ID3 tags generates TimedMetaData.

public void onVideoSizeChanged(@NonNull SessionPlayer player, @NonNull VideoSize size)

Called to indicate the video size

The video size (width and height) could be 0 if there was no video, no display surface was set, or the value was not determined yet.
