The version you have worked on a series of Sharp Zaurus handhelds, don't 
remember if your version was one of them. Anyway due to lack of Sharp 
Zaurus hardware none of the developers is currently actively maintaining 
this port.

The videolan team is looking for someone who actively wants to maintain 
this the port of VLC to the Sharp Zaurus PDA's. Perferably someone which 
has the hardware. His role would be compiling and packaging libraries 
needed by VLC and VLC itself. The Videolan team would like the resulting 
packages to be put on the VLC Sharp Zaurus download page. Just sent an 
e-mail to vlc-devel at videolan.org.

Might be a fb driver or QT issue, but cannot be sure without access to 
the hardware.

Probably outside, but the version you got is *very* old, drivers and 
hardware changed since then.

Can you view the mpeg file on your desktop?

These versions are very old and probably conflict with some API's on 
your current Sharp Zaurus. This will result in very strange behaviour.

You need to compile ffmpeg for that, with --enable-shared --enable-pp 
--enable-release, but be sure to compile every library that is needed by 
ffmpeg before compiling ffmpeg itself.

See above.
