As the title of the stream indicates, this is a live stream and ExoPlayer's SSAI media source currently removes the duration for live streams. I'm not entirely sure, but this may have been accidental and I can look into adding it back.

I have rechecked this issue on the latest version. But there seems to be another problem going on.
The version can be seen on the image I attached, duration is showing a negative value.
I'm not sure exactly how to reproduce it, but I think you can reproduce this error by following the steps below:

1. Open the content HLS Live: Big Buck Bunny (mid) 3 ads [10/10/10s]
2. After the Ad is finished playing, you seek it back to position 0. (Or seek it to the end position, then seek it to position 0 again).
3. You can see duration is showing negative value.

You can also see the problem in the video I attached.

Can you please check this problem ? Thank you.

What you circled in the screenshot is the current position, not the duration. The duration is the 01:10 next to it. The position may become negative in a live stream if you seek back or pause and then fall out of the live window. This may mean that future loads may fail, but playback is likely to continue initially with the data that has already been buffered.

Oh, sorry, my bad, I mean the current position, not the duration.

The position may become negative in a live stream if you seek back or pause and then fall out of the live window. This may mean that future loads may fail, but playback is likely to continue initially with the data that has already been buffered.

Sorry, but this problem can be fixed ?
