I am trying to implement gapless media player. I create a list of MediaPlaybackItem's and add them to an instance of MediaPlaybackList. The media playback items are created for files, uploaded on a server, using MediaSource.CreateFromUri().

So far so good, but when I play the media, there is a clearly audible pause when playing transitions from one item to another. I want to avoid this.

According to the documentation:

Items in a MediaPlaybackList are rendered using gapless playback.

However, the gap is there. I tried to set 'MediaPlaybackList.MaxPrefetchTime' but it did nothing.

Is there a way I can implement gapless playing using MediaPlaybackList?

CodePudding user response：

Indeed, the gap was caused because of the delay while opening the stream of the next MediaPlaybackItem from the Uri source.

What I did is to call OpenAsync() on each media playback item before starting the player:

foreach (var item in mediaItems)
{
    _ = item.Source.OpenAsync();
}

This is a oversimplified example, where I do not await the async methods and therefore do not trap potential errors. Since I do not want to have a delay while the songs are opened, the best way would be to make a list of all async methods, and wait for them using 'Task.WhenAll' in a separate task.
