mencoder is a great program too but I have been successfully using ffmpeg to convert video files to 3gp. Will be blogging on this quite soon. Following command worked for me to convert a file to mp4 ffmpeg -i inputfile.flv -acodec copy -s 480x320 -r 30 -b 768 -ar 44100 -ab 64 -y outputfile.mp4 Remember to put -acodec copy otherwise ffmpeg uses aac which will not give you any sound. You can play around with size(-s), frame rate(-r), bitrate(-b), audio rate(-ar) and audio bitrate(-ab). -- ubuntu-in mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-in
