Source: smplayer
Version: 21.8.0-1

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
smplayer could not be built reproducibly.

This is because it embedded a timestamp in the smplayer.appdata.xml
file. Strangely, this line was commented out (from an XML parser's
perspective, that is), but it still renders the build unreproducible:

   -    <!-- <release version="21.8.0" date="2022-11-25"/> -->
   +    <!-- <release version="21.8.0" date="2021-10-24"/> -->

Patch attached that uses SOURCE_DATE_EPOCH.
