The C code on Github is just the converter that runs on the PC, to 
convert your video to .dvo format which plays on the Spectrum. The 
player itself is done in assembler: http://divideo.zxdemo.org/player.asm

It is possible to code C for the Speccy using Z88DK -
http://www.z88dk.org/forum/ - although that's not an option for a video 
player, where you need to 1) keep everything as fast as possible and 2) 
know exactly what it's doing at the clock cycle level (so that you can 
update the audio at the right times).
