Ubuntu howto: converting .FLV to MPG

sudo apt-get install ffmpeg

ffmpeg -i video.flv -ab 56 -ar 22050 -b 500 -s 320x240 video.mpg

finally to make your life easier just put it a script file to excute later

mkdir ~/scripts;
echo 'ffmpeg -i $1 -ab 56 -ar 22050 -b 500 -s 320x240 $1.mpg' > f2mpg.sh;
mv Flv2Mpg.sh ~/scripts

now whenever you want to convert FLV file to mpg just shot the

 ~/scripts/f2mpg.sh Flv_video_file_name.flv

for further information check 

man ffmpeg

    I only get
    [flv @ 0x82c5740]Unsupported video codec (4)

    So, is there anyway to
    a) adjust your solution
    b) use another converting solution
    c) get totem, vlc or mplayer to play the file
    d) get another player to play the file

    all solutions must be for Linux of course, preferably Ubuntu…

    Can you give yourself a name? and please paste the error here.
    maybe you should follow the instructions here.

    Larsson,
    Weird, it should work; anyway please try

     file video.flv

    it should return

    video.flv: Macromedia Flash Video

    else it would be a different video format with incorrect .FLV extension

    actually I just tried to install ffmpeg on new ubuntu installation and I
    just had to install

    ffmpeg libdc1394-13 libimlib2

    and it worked just fine

    ffmpeg -i video.flv -ab 56 -ar 22050 -b 500 -s 320x240 vide o.mpg

Seems that stream 1 comes from film source: 1000.00 (1000/1) -> 30.00 (30/1)
Input #0, flv, from 'video.flv':

Stream #0.0: Audio: mp3, 22050 Hz, mono
Stream #0.1: Video: flv, yuv420p, 320x239, 1000.00 fps
Output #0, mpeg, to 'video.mpg':
Stream #0.0: Video: mpeg1video, yuv420p, 320x240, 30.00 fps, q=2-31, 500 kb/s

    so finally if the file video.flv return a correct macromedia format then the solution would be beyond my experience how ever I’ll try to digg for a solution

    Jade,
    I’m not that expert but I found similar problem and solution at ffmpeg-user mailing list the guy had similar problem and they helped him to get it solved.

    Quicksilver_Johny,
    First go through this guide
    if it didn’t work after installing the restricted format then it’s not supported :(

  15. Roy Says:

    Here’s a small tweak for your script that cleans up the final filename a little:

    #!/bin/bash
    OLD=$1
    NEW=`basename $OLD .flv`
    ffmpeg -i $OLD -ab 56 -ar 22050 -b 500 -s 320×240 $NEW.mpg

    hmm, well I don’t know but I’ll go through the documentations again and see if I can come up with a script that convert and give explanation when there is a problem.

    You may need to update your version of ffmpeg. I compile ffmpeg from source on ubuntu every so often. I use ffmpeg to convert youtube and google flash videos from to 3gp and mp4 clips on MyMobileClips

  25. Dusty Rancourt Says:
    October 26th, 2006 at 7:38 AM

    This is marvelous, thank you. One suggestion, if I may, though — your script as-is fails on file names with spaces. A small modification fixes this:

    echo ‘ffmpeg -i “$1″ -ab 56 -ar 22050 -b 500 -s 320×240 “$1.mpg”‘ > f2mpg.sh

    Thank you so much for this excellent solution. I am most grateful!

  26. linux enthusiast Says:
    October 30th, 2006 at 6:57 AM

    here is my conversion script you can only do one video at a time
    the flv converts to mpg and keeps the original file name.

    #!/bin/bash

    output=`ls *.flv -1|cut -f1 -d”.”`
    ffmpeg -i *.flv -ab 56 -ar 22050 -b 500 -s 320×240 $output.mpg
    rm *.flv
    exit

  27. linux enthusiast Says:
    October 30th, 2006 at 7:05 AM

    also you can only have one flv in the folder at a time
    you should put the script in /usr/bin make a folder just for converting video put a shortcut to the script(inside the folder) that runs in the terminal drag one flv into the folder and click your shortcut
    voila you have an mpg and the flv gets deleted. sorry for 2 post just wanted to make it easy on someone else.Took a while to get this right i’m not a bash expert.

  28. Jake Says:
    December 17th, 2007 at 3:33 PM

    Why not simply add a command to your .bashrc instead of making a script?
