Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.

ffmpeg cannot open a simple microsoft wav file exported with Audacity
18 février 2014, par sebpiqI have exported a sound file to microsoft wav using Audacity.
I am trying to open this file with ffmpeg :ffmpeg -i steps-stereo-16b-44khz.wav /tmp/test.ogg
and here's the ouput I get :

steps-stereo-16b-44khz.wav: could not find codec parametersIf I export the same file to .ogg or .aiff, no problem, the following works fine :

Any idea what could be wrong ?
A link to my wav file so you can try to reproduce.
NB my final goal is to slice the audio file. I know I can export file directly to .ogg with audacity. This is just a test case.
EDIT
Getting file info with another program like sox, works well :
sox --info steps-stereo-16b-44khz.wav
