      1. salut,

        mencoder

        1) installer mencoder

        2) créer le fichier :

        [redfox@fedora8 Bureau]$ vi flv2avi.sh

        collez-y le code suivant :

        #!/bin/sh 
        
        if [ -z "$1" ]; then
          echo "Usage: $0 {-divx|-xvid} list_of_flv_files"
          exit 1
        fi
        
        # video encoding bit rate
        V_BITRATE=1000
        
        while [ "$1" ]; do
          case "$1" in
            -divx)
              MENC_OPTS="-ovc lavc -lavcopts \
                vcodec=mpeg4:vbitrate=$V_BITRATE:mbd=2:v4mv:autoas  pect"
              ;;
            -xvid)
              MENC_OPTS="-ovc xvid -xvidencopts bitrate=$V_BITRATE:autoaspect"
              ;;
            *)
              if file "$1" | grep -q "Macromedia Flash Video"; then
                mencoder "$1" $MENC_OPTS -vf pp=lb -oac mp3lame \
                  -lameopts fast:preset=standard -o \
                  "`basename $1 .flv`.avi"
              else
                echo "$1 is not Flash Video. Skipping"
              fi
              ;;
          esac
          shift
        done


        enregistrez le fichier.

        3) rendez-le exécutable :

        [redfox@fedora8 Bureau]$ chmod 755 flv2avi.sh

        4)
        [root@fedora8 Bureau]# mv flv2avi.sh /usr/bin/

        5)
        redfox@fedora8 Bureau]$ flv2avi.sh -xvid making_a_trumpet-Yl8qfu-ojTQ.flv

          Sinon il y a avidemux qui est plus ou moins un frontend de ffmpeg et mencoder.

          Le gros avantage, c'est qu'un gosse de 6 ans pourrait l'utiliser ;)
