Convert video format from flv to avi

最近由於需要將一些視頻由flv格式轉化為avi格式，為了自動化轉換，我寫了如下指令碼：

#!/bin/bashFFCMD='/cygdrive/c/work-dir/ffmpeg/ffmpeg.exe'  # path to ffmpe tools#check output directory existif ! test -d $2;then  mkdir $2fi#convert flv to avifor f in $(ls $1/*.flv);do  if test -f $f  then    echo -e "\nConverting $f"    FILENAME=$(basename $f | cut -d '.' -f 1)    #echo $FILENAME    $FFCMD -i $f -r 25 -b 750k -y $FILENAME.avi 2>> log.txt    mv -f $FILENAME.avi $2  else      echo -e "\nSkipping $f - not a regular file";  fidone  #Usage##You can convert the all of flv files in flv-folder/ to avi file located in out-avi-folder/ by following command#$./convert-flv-2-avi.sh flv-folder/  out-avi-folder/

 

對於視頻/音訊轉換，一般都會用到ffmpeg這個工具，詳情可以參考：http://www.ffmpeg.org/
