  • #/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

  • ffmpeg record audio from Xvfb on Centos

    25 mai 2017, par boygiandi

    I’m trying to record audio from Xvfb. And I have some problems :

    1. What’s the different between alsa and pulse. I get confuse
    2. Server Centos have no soud card :

    arecord -l

    arecord : device_list:268 : no soundcards found...

    1. I may have many Xvfb process, how to record video and audio from specific Xvfb process. I checked this https://trac.ffmpeg.org/wiki/Capture/ALSA#Recordaudiofromanapplication but still don’t understand how it works.

    ffmpeg -f alsa -ac 2 -i hw:0,0 -acodec pcm_s16le output.wav

    I seen many command like this, but I don’t know how to get hw:0,0 ( id of sound card ? )

    Please help. Thanks

  • Executing ffmpeg from Python

    24 mars 2016, par shardulc

    I’m trying to run ffmpeg on all the WAV files in a directory to convert them to mp3. This command works fine when I run it from the command-line, on my Fedora Linux machine :

    /usr/bin/ffmpeg -i "Name With Spaces.wav" Name_With_Spaces.mp3

    where Name With Spaces.wav is a file in the current directory. However, in Python 3.2 running in the same directory :

    import os
    
files = os.listdir()
    
os.execl('/usr/bin/ffmpeg', '-i \"' + files[0] + '\"', files[0][:-4].replace(' ', '_') + '.mp3')

    gives me the error (from ffmpeg) : At least one input file must be specified. I don’t see why this isn’t working, because '-i \"' + files[0] + '\"' evaluates to -i "Name With Spaces.wav" and files[0][:-4].replace(' ', '_') + '.mp3' evaluates to Name_With_Spaces.mp3.

    I’ve tried escaping spaces, using different quotation marks, using the full path (like /home/.../music/Name\ With\ Spaces.wav), and actually replacing the arguments with the real text, but nothing works. How can I get this to work ?
