Hola,

Nose que pasa que cuando convierto un video con el ffmpeg de .avi, .mpg, etc a .flv al pasarse pierde el audio :S, he probado todo tipo de comandos, aqui les dejo algunos:

Código:

/usr/local/bin/ffmpeg -i /mnt/videos/27.avi -acodec mp3 -ar 22050 -ab 32 -f flv -s 320×240 /mnt/flvideos/27.flv

/usr/local/bin/mencoder /mnt/videos/27.avi -ovc lavc -oac mp3lame -o /mnt/flvideos/27.flv


/usr/local/bin/ffmpeg -i /mnt/videos/27.avi -ar 22050 -ab 32 -f flv -s 320x240 /mnt/flvideos/27.flv


/usr/local/bin/ffmpeg -i /mnt/videos/27.avi -s 396×324 -ar 22050 /mnt/flvideos/27.flv


/usr/local/bin/ffmpeg -i /mnt/videos/27.avi -ab 56 -ar 22050 -b 500 -s 320×240 /mnt/flvideos/27.flv

Y nada..alguna posible solución/codigo alternativo???

Un saludo!
