* include/decoder_fifo.h :

Browse Source 
- Proprification des commentaires ;

* include/input.h :
- i_pts �tait un u32 mais doit �tre un s64 ;
- Question ouverte au Ptyx : pourquoi mtime_t est un u64 ?
  Est-ce que c'est mauvais de passer mtime_t en s64 ?
  Est-ce que �a fait modifier beaucoup de code ?

* input/input.c :
- Correction d'un cast ;
