Thanks to all for the feedback. <br>
Given other's experience, I tested with Linux-FC14 and it works
for me too.<br>
It must be a CentOs 6 specific issue. Most likely a decoder is
missing, because it isn't strictly Open Source. RH is very
accurate in providing only purely OS software. Sometimes it's a
nuisance.<br>
I'll investigate.<br>

It's not because of "open source"-ness, but due to patents. The
H.264 codec is heavily patented in the United States and other
countries and requires an expensive license fee to use:<br>

<a class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Patent_licensing">http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Patent_licensing</a><br>
<br>
Free browsers such as Firefox only provide H.264 playback
capability, if the underlying OS has the codec installed. So, it
only works in Windows and Android, because Microsoft and Google have
paid the license fees for distributing the codec with the OS.<br>
<br>
If you want to support free operating systems, it's better to also
provide WebM or Ogg/Theora versions of the video:<br>

<a class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/Theora">http://en.wikipedia.org/wiki/Theora</a><br>
<br>
Unfortunately, there are some very popular devices (e.g. the iPhone
and the iPad) that *only* support H.264 and that don't allow you to
install other codecs, so if you want the best compatibility, you
need two versions for every video - one H.264 and one WebM or
Ogg/Theora :(<br>
