How to get the entire content Duration of a MediaItem, not just the clip length?

[REQUIRED] Question

I have a list of MediaItems with different start positions.

MediaItem mediaItem = new MediaItem.Builder()
    .setUri(trackUri)
    .setClipStartPositionMs(startPos)
    .setClipEndPositionMs(C.TIME_END_OF_SOURCE)
    .build();

When a particular MediaItem is being played, the Player is just returning the duration of the clip, not the total length of the track. Is there a way where I can get the total length of the track, not just the clip length?

@pavan245 - For only changing the start clip position, my solution posted above will work. For the end position, marking this as a duplicate of #3163 as per Toni’s response above.

If you’re only changing the start clip position then I think you can retrieve the entire content duration like:

@Override
public void onTimelineChanged(Timeline timeline, @TimelineChangeReason int reason) {
  if (!timeline.isEmpty()) {
    long durationMs = timeline.getPeriod(0, new Period()).getDurationMs();
  }
}

Note that you can also retrieve the timeline from Player.getCurrentTimeline. @pavan245 - Does that work for you?

The same trick does not work if you set an end clip position, however. This may not be relevant to your use case, but is something we should think about. @tonihei - Do you understand why that’s not the case? If both start and end are clipped, I think I’d expect the period and window to look like:

<----------- original content ----------->
<-------------- period ------------------>
            <----- window ----->

where-as it seems they look like:

<----------- original content ----------->
<-------------- period -------->
            <----- window ----->

I tried changing ClippingTimeline.getPeriod to do what I expected, but then playback doesn’t transition to the ended state once the clip end point is reached. Which also seems unexpected to me.
