I use winff (the GUI for ffmpeg) to convert audio/video to different formats. Yesterday I was trying to convert an flv video to 3gp (so that I could see it on my mobile phone), but it doesn't show the option to convert to 3gp. Are codecs missing in ffmpeg? Do I need to download such codecs from the repositories? Please, help.
Found a solution. Installed Mobile Media Converter which use ffmpeg and mencoder to do conversions. It also has a nice GUI. Thanks for the help.
