I just make a new media-player-info  release, which I've used to put into /srv/www.freedesktop.org/www/software/media-player-info/ , so that they end up at https://www.freedesktop.org/software/media-player-info/ .
However, that directory is now owned by root:root, so I don't have permission any more to write there. I put the tarball on https://people.freedesktop.org/~martin/ for now, but it would be nice to continue to use the "official" location.
oops, fixed now!
Awesomely fast, thanks Daniel! I put the tarball to the official location now.
