Not show remaining time



It is a very weird issue. You can easily reproduce this issue by setting source of MediaPlayer by:
  • removed -
(Note that the above source url will be expired soon. In this case, please comment and I will provide new source url.)

MediaPlayer did not show remaining time and the timeline bar was not scrollable .

Please help me to solve this issue.

Thank you in advance!

This will happen if phonesm has trouble finding the duration of the stream. For HLS, this means sane durations on all the segments and a #EXT-X-ENDLIST tag.

If you take a look in the debug Output window when playing the stream, do you see any errors or warnings?

(I saw this issue too late to grab a copy, but perhaps you could attach or PM a copy of the stream .m3u8?)

Hi henric,

I pm you with the new source url.

Please check you pm.

There is a segment with zero duration, which trips some safety checks in HlsPlaylistSegmentManager.cs. This might be enough to get things working for you:

This hasn't been tested and I need to dig into the code a bit further to make sure that this will not cause other problems before checking this into the main tree.

Let me know what happens if you get a chance to test it.

Hello henric,

Thank you very much for you support.

I have tested the above change, it worked with the video I sent you. I will do more tests to ensure it work properly for another videos and will let you know if I find any problems.

Best Regards
