I get to know this command because my mplayer having problem playing flv downloaded from youtube. Therefore I google it and found that it is a command line can actually convert it into mpg.
To convert flv, let say myvideo.flv to myvideo.mpg, you can do this:
ffmpeg -i myvideo.flv -ar 22050 -b 500 -s 320x240 myvideo.mpgI check out man for ffmpeg, i couldn’t find at my local machine and I search from the internet, it is quite brief.
Anyway, -i is input, -ar is to set audio sample rate to 22050 Hz, -b is to make it DIVX compatible -s defines its video size.
I turn it into script so that it is easy to trigger next time.
#!/bin/sh
if [ -n "$1" -a -n "$2" ]
then
ffmpeg -i $1 -ar 22050 -b 500 -s 320x240 $2
else
echo "Usage: `basename $0` source.flv target.mpg"
fiif [-n "$1" -a -n "$2"] is actually check to see if source and destination video is not specified, then display the usage.
Copy these line into a text file call flv2mpg and change it to executable by doing this
chmod a+x flv2mpgSo next time if want to convert to mpg, just do this
./flv2mpg myvideo.{flv,mpg}

I tried doing that but it said that the file is truncated and/or corrupted… and im not really sure what to do…

And it says permission denied…

File truncated or corrupted probably means your flv, I am not sure, you didn’t mention what have you did to get this.
Same to permission denied, it probably means you haven’t chmod to the script? or other reason..

[...] -i is input file, -ar is audio rate in Hz. Just a slides of time, and you are done. And good thing about command line is you can put that into a bash script to do a batch converts.

I wanted to make an impression at a household reunion and recall the names of all of the new husband’s household members. There was one gent whom I’d asked his name and tried incredibly to bear in mind but failed repeatedly. Finally he bailed me out and said his name was Dick. Without a thought I swiftly said, “Gosh, how could I forget? You *look* like a ‘Dick’!!!”
