QMediaPlayer can't play mp3 mounted over CIFS
I'm building a simple media player using QMediaPlayer on Linux. I'm trying to play a QMediaPlaylist of files mounted via CIFS. Whenever I start the player, the first six items on my Playlist get a "Warning: no decoder found for type ...". After skipping the first six items everything works like a charm, even if I later jump to the beginning of the playlist.
Also this problem only occurs after a fresh boot of my computer. If I restart my application after having it skip the first six entries, everything works normally.
Any hints how I could work around this problem?
