When track is changed during playback, `playbackPositionUs` may be in middle of a chunk and `loadPositionUs` should be the start of that chunk. In this situation `loadPositionUs` can be less than the current `playbackPositionUs`, resulting into negative `bufferedDurationUs`. It translates to having no buffer and hence we should send `0` for `bufferedDurationUs` when creating new instances of `CmcdData.Factory`.

ExoPlayer SmoothStreaming module
Provides support for SmoothStreaming content in ExoPlayer.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-exoplayer-smoothstreaming:1.X.X'
where 1.X.X is the version, which must match the version of the other media
modules being used.
Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
Adding a dependency to this module is all that's required to enable playback of
SmoothStreaming media items added to ExoPlayer in its default configuration.
Internally, DefaultMediaSourceFactory will automatically detect the presence
of the module and convert a SmoothStreaming MediaItem into a SsMediaSource
for playback.
Similarly, a DownloadManager in its default configuration will use
DefaultDownloaderFactory, which will automatically detect the presence of
the module and build SsDownloader instances to download SmoothStreaming
content.
For advanced playback use cases, applications can build SsMediaSource
instances and pass them directly to the player. For advanced download use cases,
SsDownloader can be used directly.
