title: Collection of video samples with different codecs
body: <p>I'm in a middle of trying to buy iptv device and of course different iptv devices supports different kind of file formats, video codecs and audio codecs.</p>
  
  <p>Can someone recommend me a collection of videos which would be encoded using different versions and different video and audio codec - as much as possible different combinations. </p>
  
  <p>I understand that supporting everything (all video and all audio codecs) is pretty much impossible - so it would be good if they are sorted in most used - least used order. For example:</p>
  
  <ol>
  <li>.avi - xvid vx.xx video codec + yyy audio codec</li>
  <li>.mkv - ....</li>
  <li>YouTube .flv format ...</li>
  <li>...</li>
  </ol>
  
  <p>But of course which codec is used and where depends of which movies you get and from where. I could perform ordering of videos on my own.</p>
  
  <p>Preferably so that videos would be as small as possible - for example 20 seconds per clip, and some video / audio which you can easily inspect - understandable video / audio. (language does not matter)</p>
  
  <p>I suspect also that this kind of collection does not exists - then it's ok to give me video clips for different codecs here, and I will collect them into one collection.</p>
  
  <p>Eventually I want to place all these clips on usb stick - come to shop and try out which of clips can be played and on which iptv-device.</p>
