Every once in a while, a file gets uploaded that is a video but recognized by Wikimedia Commons as an audio file, which then does not play properly. The latest example for that is https://commons.wikimedia.org/wiki/File:Intraspecific-Combinations-of-Flower-and-Leaf-Volatiles-Act-Together-in-Attracting-Hawkmoth-pone.0072805.s001.ogv , taken from http://dx.doi.org/10.1371/journal.pone.0072805.s001 . It is better not to upload such files than to upload them in this corrupted state. Can we detect such corruption on our end? The file above played OK in VLC but triggered the following error message from Movie Player: "Python (v2.7) requires to install plugins to play media files of the following type: video/x-gst-fourcc-mp2v decoder".
