repro steps: open a media file that is at least 35 minutes long seek the media file (using the player you opened it with) to past 33:20 observe the seek bar in mediacontroller. this is most likely caused by QML's limit of 2000000000 length for ints, and mpris's use of very precise positions.
*** This bug has been marked as a duplicate of bug 377623 ***
While this is technically a duplicate issue, the resolution of #377623 did not cover the position, which is what this issue is about. I'd like to provide new reproduction steps though: 1) Open a file in a media player and seek it to 34 minutes 2) Try to seek the file using the Plasma media player 3) The media player seek bar resets to 00:00 I've also found that pushing past the point of 36 minutes seems to reset the Plasma media player back to 00:00
Created attachment 114791 [details] Changing the position to a double the same way the length was changed to a double fixes the media player
Thanks for the investigation. Is the patch from comment #3 the correct diff, or the reverse diff going from the fixed version to the current version?
It is in reverse, my bad. I wrote it in a hurry and ended up swapping the operands.
Thanks for your patch! Indeed changing the property to double should fix this since we had a similar overflow issue with the "Length" property that was also changed to a double. Can you please upload that patch to Phabricator [1] for review, as patches on the bug tracker often get overlooked? You'll find more information on our wiki [2]. Thanks!

Git commit 1bb02b98cfedfd6b51ac8de0c34a5778659433f7 by Kai Uwe Broulik, on behalf of Arsen Arsen. Committed on 06/09/2018 at 08:29. Pushed by broulik into branch 'Plasma/5.12'. [Media Player] Change int to double for positions In previous versions of Plasma, media player had an overflow bug in positions, leading to the player resetting to 00:00. This only affects files longer than around 33 minutes 20 seconds.
