• FFMPEG failing to convert to ogv [closed]

  25 juillet 2012, par Todd R

  I have several videos I'm trying to convert to mp4, swf and ogv. I've got the mp4 and swf's working, but ogv is failing and I'm not sure why. I understand all the arguments you can pass to ffmpeg, but feel like getting the correct ones is a huge guessing game. Any suggestions on what I can change to get this to work would be much appreciated.

  Here's the command I'm using :

  ffmpeg -i /private/var/tmp/phpU5KPR7 -y -s 330X240 -acodec libvorbis -vcodec libtheora outputpath/Videos/1.ogv 2>&1

  And here are the results :

  2012-07-24T19:05:11-07:00 INFO (6): Creating ogv for 1 returned 1:
