A PDF file can be converted into text by the Tool belonging to the XPDF package pdftotext:

pdftotext irgendein.pdf

This instruction produces a text file with the name irgendein.txt with contents of any PDF. They can work on this file now completely normally. The parameter - layout ensures for the fact that the appearance of the PDF file is transferred as far as possible to the text file:

pdftotext -layout irgendein.pdf

If you want to transfer only certain sides from a PDF file to the text excerpt, goes with the parameter - f (for first PAGE) and - l (for last PAGE):

pdftotext -f 3 -l 7 irgendein.pdf

in this example only the pages from 3 to 7 after irgendein.txt would be taken over.

今天找到个好东西：）

先从Mencoder这个开始，将所有格式转AVI，

RMVB转AVI

mencoder 1.rmvb -oac mp3lame -lameopts preset=64 -ovc xvid -xvidencopts bitrate=600 -of avi -o rmvb.avi

RM转AVI

mencoder 1.rm -oac mp3lame -lameopts preset=64 -ovc xvid -xvidencopts bitrate=600 -of avi -o rm.avi

MPEG转AVI

mencoder mp4.mpeg -oac mp3lame -lameopts preset=64 -ovc xvid -xvidencopts bitrate=600 -of avi -o mp4.avi

MOV转AVI

mencoder qtime.mov -oac mp3lame -lameopts preset=64 -ovc xvid -xvidencopts bitrate=600 -of avi -o qtime.avi

WMV转AVI 包括WMV7到WMV9，只实验到WMV9

mencoder m7.wmv -oac mp3lame -lameopts preset=64 -ovc xvid -xvidencopts bitrate=600 -of avi -o m7.avi

RV转AVI

mencoder 1.rv -oac mp3lame -lameopts preset=64 -ovc xvid -xvidencopts bitrate=600 -of avi -o rv.avi

等等……格式，参数不变，改文件名就好了。

接下来是FFMPEG上场。

AVI转FLV

ffmpeg -i test.avi -ab 56 -ar 22050 -b 500 -r 15 -s 320x240 test.flv

抓图JPG。

ffmpeg -i 2.wmv -y -f image2 -ss 8 -t 0.001 -s 350x240 test.jpg

3GP转FLV

mencoder -vf scale=320:240 -ffourcc FLV1 -of lavf -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -ovc lavc -lavcopts vcodec=flv:vbitrate=200 -srate 22050 -oac lavc -lavcopts acodec=mp3:abitrate=56 ok\1.3gp -o ok\3gp.flv

MOV转FLV

mencoder -vf scale=320:240 -ffourcc FLV1 -of lavf -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -ovc lavc -lavcopts vcodec=flv:vbitrate=200 -srate 22050 -oac lavc -lavcopts acodec=mp3:abitrate=56 ok\qtime.mov -o ok\mov.flv

RMVB转FLV

mencoder -vf scale=320:240 -ffourcc FLV1 -of lavf -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -ovc lavc -lavcopts vcodec=flv:vbitrate=200 -srate 22050 -oac lavc -lavcopts acodec=mp3:abitrate=56 ok\1.rmvb -o ok\rmvb.flv

WMV转FLV

mencoder -vf scale=320:240 -ffourcc FLV1 -of lavf -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -ovc lavc -lavcopts vcodec=flv:vbitrate=200 -srate 22050 -oac lavc -lavcopts acodec=mp3:abitrate=56 ok\m9.wmv -o ok\m9.flv

等等等…………

以上的参数通用，只要在输入的ok\m9.wmv换成你自己相应的格式就好，绝对可以，这次测试完全OK，效果点这里，给大家看看，我近期的成果，已实现的。

裁图方面，跟以前一样的，我再贴一份。

ffmpeg -i ok\3gp.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 3gp.jpg

ffmpeg -i ok\mov.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 mov.jpg

ffmpeg -i ok\mpeg.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 mpeg.jpg

ffmpeg -i ok\mp1.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 mp1.jpg

ffmpeg -i ok\mp2.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 mp2.jpg

ffmpeg -i ok\rm.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 rm.jpg

ffmpeg -i ok\rmvb.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 rmvb.jpg

ffmpeg -i ok\rv.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 rv.jpg

ffmpeg -i ok\mp4.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 mp4.jpg

ffmpeg -i ok\avi.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 avi.jpg

ffmpeg -i ok\m7.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 m7.jpg

ffmpeg -i ok\m8.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 m8.jpg

ffmpeg -i ok\m9.flv -y -f image2 -ss 8 -t 0.001 -s 320x240 m9.jpg


以上转完FLV，有个缺陷，就是FLV播放时不能拖放，要用下面的一个软件来修复。

在服务器上自动转，用命令行的。用这个，
flvmdigui.exe 要有用户界面的，手动修复的，用这个

flvmdi.exe 使用方法:
命令提示符下输入>flvmdi inputFile [outputFile][/s] [/x] [/e] [/k]

给个例子，后面的参数不加也可以修复，比如。

flvmdi m7.flv

这样就行了。
