[avi @ 0xb7f2f2a8]Could not find codec parameters (Video: mpeg4)
videodump.avi: could not find codec parameters

Praticamente se cerco di convertire un video in 3gp me lo da sempre....

videodump.avi: could not find codec parameters

Dice che non gli hai specificato nessun tipo di pametro per il codec... Non me lo ricordo più però se è un xvid, devi mettere vcodev=xvid, se è mpeg1/2 vcodec=mpeg12 e via dicendo... Però NON ne sono sicuro.

Cercando su google ho trovato questo script... lo salvi in make3gp e poi gli fai sopra un chmod +x, poi fai make3gp file.avi. Ti serve anche ffmpeg.
