 ===== Conversion de format =====
+Bons articles:

 Pour WEBM:
@@ Ligne 11: / Ligne 14: @@
 Pour FLV:
-  avconv -i the_video.mp4 -ar 44100 the_video.webm
+  avconv -i the_video.mp4 -ar 44100 the_video.flv
 Beaucoup (extrêmement) plus rapide que WEBM. Obligé d'indiquer audio_rate (-ar) sinon ne se lance pas, erreur : //Could not write header for output file #0 (incorrect codec parameters ?): Function not implemented//
 ===== Web player =====

+====Pour le web====
+We need to encode our video with several different codecs so **that every browser can play** the one it likes. Codecs are a way to compress digital media. There are dozens of video codecs, but the ones you should know about for web videos are **H.264, vp8, and theora**. Each type of encoded videos is housed in a different type of container. Again, there are dozens of video containers, but for web videos you only need to know about **mp4, webm, and ogg**.
