this first commit reduces unneeded code complexity and removes one full message-db load.
the second commit shows an alert with instructions in case a video-preview could not be generated (with high chance, also Preview will fail to play the file)
closes #1909
of course, this can be improved further, however, regarding that .webm video is not an officially supported format, this seems good enough and already a good improvement, giving the ppl an idea how to play that at all (it was not even clear to me :)
