Beste Leden,
Ik heb FFmpeg op centos laten installeren met het volgende:
# FFmpeg
# FFmpeg-PHP (optional)
# Mplayer + Mencoder
# flv2tool
# Libogg + Libvorbis
# LAME MP3 Encoder
Na het testen blijkt mpeg filmpjes niet worden afgespeeld, er wordt wel een flv file aangemaakt maar zonder inhoud 0.
Zou iemand een een blik willen werpen op het volgende wie weet zien jullie wel iets?
