  • #/bin/sh in one line

    27 juillet 2012, par GoodGuyGreg

    I'm working on some Haskell project using FFmpeg. I need to batch create from a media folder with MP4 files and create screenshots from all of them. I got the code and am using it on a terminal in Unix. It works, but how do I make it in one line to be executed in system "xxxx" in Haskell ?

    If not using several system"xx"...

    #/bin/sh
    
for i in $(ls *.mp4)
    
do
    
    ffmpeg -i $i -vframes 7 -y -ss 10 -s 150x150 -an -sameq -f image2 -r 1/5  $i%1d.jpg
    
done

    I tried :

    import System.Cmd
    
function = do{system "#/bin/sh";
    
system "for i in $(ls *.mp4)";
    
system "do";
    
system "ffmpeg -i $i -vframes 7 -y -ss 10 -s 150x150 -an -sameq -f image2 -r 1/5  $i%1d.jpg";
    
system "done";}

    but it gives a error :

    -vframes: No such file or directory
    
/bin/sh: Syntax error: "done" unexpected

  • why I can't compile x264 or ffmpeg downloaded from git

    4 avril 2013, par Monjura Rumi

    It has been just a few days that I am using x264, ffmpeg and trying to take help from codes in git. I am always having some peculiar problem. It seems like no one or few people faced such problems. Here is one of those problems. If I download x264 or ffmpeg using git then I could not compile that source code. At first terminal will show ./configure: Permission denied. Then If I change permission of configure file using chmod 755 command then it will show ./configure: /bin/bash^M: bad interpreter: No such file or directory. To build x264 and ffmpeg I have followed this link https://github.com/lince/libffmpeg-c/wiki. My attempt to compile x264 has failed. Can you please tell me how can one use source code downloaded from git ?
