title: FFmpeg convert .mov to .ogv
body: <p>I have some troubles converting my .mov to a .ogg file using FFmpeg.</p>
  
  <p>This command should work, right?</p>
  
  <pre><code>ffmpeg -i test.mov -s 640x320 -vcodec libtheora -acodec libvorbis out.ogv
  </code></pre>
  
  <p>It gives me this output</p>

  <p>It seems right, right?</p>
  
  <p>But the movie is only about 1 second long. 
  Why is that?</p>
  
  <p>I do not have access to ffmpeg2theora, so please dont suggest that :)</p>
