批量将rmvb转为avi
#ipod touch可用for i in *.rmvb; do mencoder -vf harddup -oac mp3lame -lameopts vbr=3 -ovc xvid -xvidencopts fixed_quant=4 -of avi $i -o `echo $i | sed -e
‘s/rmvb$/avi/’`; done
批量将DVD转为avi
for i in *.VOB; do mencoder -oac mp3lame -lameopts aq=7:vbr=2:q=6 -srate 44100 -ovc xvid -xvidencopts fixed_quant=4 -of avi $i -o `echo $i | sed -e
‘s/VOB$/avi/’`; done
批量将任何格式的电影转为ogv
#sudo apt-get install ffmpeg2theora #firefox3.5或chrome直接支持播放，无需安装任何解码器，注意不支持rmvb，rmvb会出现a/v不同步问题for i in *; do
ffmpeg2theora –optimize –deinterlace $i; done
批量将rmvb格式的电影转为ogv
#!/bin/bashfor i in *; do mkfifo "/tmp/$i" mencoder -quiet -vf harddup -ovc raw -oac pcm -o "/tmp/$i" "$i" & ffmpeg2theora –optimize –deinterlace
"/tmp/$i" -o "`echo $i | sed ‘s/\(.*\)\..*$/\1/’`.ogv" rm "/tmp/$i"done
利用gst来转换任意电影为ogv
#!/bin/bash
for i in *; do gst-launch-0.10 filesrc location="$i" ! decodebin name=demux \ { oggmux name=mux ! filesink location="`echo $i | sed ‘s/\(.*\)\..*$/
\1/’`.ogv" } \ { demux. ! queue ! audioconvert ! vorbisenc ! queue ! mux. } \ { demux. ! queue ! ffmpegcolorspace ! videorate ! theoraenc ! mux. } done
批量转换任意文件为ipod touch使用的mp4
