Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

it s not a oneliner !

and why not put directly the script ? You can put the link to pdf in the comment eventually isn't ?

ok I put it here :

#!/bin/sh

#

# Example script to encode video in various test formats for streaming

# by jaromil and xname

#

# commands used:

#### H.264 + MP3

# mencoder -oac mp3lame -lameopts vbr=0:br=128:mode=0

# -ovc x264 -x264encopts bitrate=$bitrate

#### XVID + MP3

# mencoder -oac mp3lame -lameopts vbr=0:br=128:mode=0

# -ovc xvid -xvidencopts bitrate=$bitrate

#### THEORA + VORBIS

# ffmpeg2theora --audiobitrate 128 --samplerate 44 -a 8

# --videobitrate $bitrate --videoquality 8

#### MPEG4

# mencoder -oac mp3lame -lameopts vbr=0:br=128:mode=0

# -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=$bitrate

if [ -z $1 ]; then

echo "usage: $0 [ h264 | xvid | theora | mpeg4 ]"

exit 1
