View source for VLC HowTo/Transcode multiple videos

== Idea ==
The idea is to use VLC to do some batch work to encode or transcode multiple files one after each other, without having to care about it. 

You may want to transcode all your videotheque to another format to play them on an [[IPod]], a [[Play on Zune|Zune]], a PS3 or a [[Play on Xbox|Xbox]].

== Codecs / Muxers ==

You have to choose the correct codecs for the device you want to transcode for.

We choose here [[H.264]] with [[AAC]] in a [[MPEG-2#TS|MPEG-2/TS]] muxer as an example.

== Command Lines ==

=== Windows ===

 for %%a in (*.VOB) do "C:\Program Files\VideoLAN\VLC\vlc" -I dummy -vvv %%a --sout=#transcode{vcodec=h264,vb=1024,acodec=mp4a,ab=192,channels=2,deinterlace}:standard{access=file,mux=ts,dst=%%a.mpg} vlc:quit

=== Unix / Linux ===

 vcodec="h264"
 acodec="mp4a"
 bitrate="1024"
 arate="192"
 ext="mpg"
 mux="ts"
 vlc="/usr/bin/vlc"
 fmt="VOB"
 dst="/home/user/"
 
 for a in *$fmt; do
 $vlc -I dummy -vvv "./$a" --sout "#transcode{vcodec=$vcodec,vb=$bitrate,acodec=$acodec,ab=$arate,channels=6}:standard{mux=$mux,dst=\"$dst$a.$ext\",access=file}" vlc:quit
 done
