i have a large video file, 500+ MB, so i cant upload it to flickr, so to reduce the size i split it into 2 files. the command shows the splitting for the first file, from 0-4 minutes. ss is start time and t is duration (how long you want the output file to be).

NOTE: when i made the second half of the video, i got a *lot* of lines like this:
frame= 0 fps= 0 q=0.0 size= 0kB time=10000000000.00 bitrate= 0.0kbit
just be patient, it is working =)
if you haven't already done so, install lame and flac:
sudo apt-get install lame flac
if you still get a permissions error using sudo, then nano the file:
sudo nano -w /sys/block/sdb/queue/rotational
and change 1 to 0

why would you want to convert mp3's to ogg? 1 reason is because ardour doesn't support mp3 files because of legal issues. this is really the only reason you would do this, unless you have really bad hearing and also want smaller file sizes, because converting from one lossy format to another isn't a good idea.
cd to the folder containing the wav files and convert them all to ogg format.
in my sample output i use the -a and -l flags to set the author and album title.
to get the oggenc program in ubuntu linux run:
sudo apt-get install oggenc
cd to the folder containing the wav files, then convert them all to flac. yeah baby!
in ubuntu, to get the flac program just:
sudo apt-get install flac
flac file input formats are wav, aiff, raw, flac, oga and ogg
search ubuntu's remote package source repositories for a specific program to see which package contains it
