看影片(支援 *.avi *.wmv)
mp3 我用 CD 轉了不少
影片...沒有
想從 YouTube 上抓一些卡通給他看...
要將 YouTube 影片檔抓下來，google 一下就有很多的教學與網站提供這樣的服務
我找到 http://kej.tw/flvretriever/ 這個網站
將 YouTube 影片網址貼上，就會出現影片真實位址的連結(*.flv格式)
下載後自行改名，並加上 flv 的副檔名，就可以用您的媒體播放軟體播了
(我有裝 codecs: http://opensuse-community.org/Restricted_Formats )
要轉成 avi 格式，我找到 http://www.linux.com/articles/56642 提供的
flv2avi.sh (感謝 Manolis Tzanidakis) 轉貼在此：
#!/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:autoaspect"
;;
-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
將上面的文字檔存成 flv2avi.sh
記得加上執行權限(chmod +x flv2avi.sh)
放在 ~/bin (或 /usr/local/bin)
$ flv2avi.sh -divx VIDEO_FILE.flv
就會將 VIDEO_FILE.flv 轉成 VIDEO_FILE.avi
我花了很長的時間(因為跟程式不熟)，從到處的 bash script 範例中抄來抄去(主要是鳥哥的網站)
拼湊出下面的 script
希望將以上步驟簡化，看可不可以教會我兒子自己動手做...
(事實證明他還是只會叫老爸幫他...)
好像是可以用啦，但寫得很難看，希望路過的大哥幫忙提供意見

#[1]Thanks Manolis Tzanidakis for flv2avi.sh
#You can get the script flv2avi.sh from http://www.linux.com/articles/56642
#or contact Author : manolis_AT_tzanidakis_DOT_gr
將上面的文字檔存成 get_youtube2avi.sh
一樣 chmod +x get_youtube2avi.sh
放在 ~/bin 或 /usr/local/bin 中
記得 flv2avi.sh 要先裝好
執行
$ get_youtube2avi [YouTube影片網址]
預設使用 YouTube title 相同的名稱，存放在 ~/影片 資料夾中
有興趣可以試試看
下面是執行的過程：
