bug description

Before the cobalt v11 update, remuxed files had (remux) suffix applied before the file extension. Now, with background processing thing, the (remux) suffix isn't being added anymore and the downloaded files have the same file name as the source file - as I use Firefox browser with auto saving on, this means that the remuxed files now have the (n) suffix before the file extension (where n = usually 1)

reproduction steps

  1. Download any video that needs remuxing
  2. Drag and Drop the video to the remux page
  3. Wait for remuxing process to finish
  4. Download the remuxed file

@wukko commented on GitHub (May 29, 2025):

as mentioned in the changelog, you don’t have to re-remux videos anymore! all videos that were processed locally should work right away.

as for the remux tab, i’ll think about adding the tag back, but it seems unnecessary.
