HandBrake-0.9.1

Uscita una nuova versione di Handbrake un utilissimo programma che permette di convertire filmati dvd in MPEG-4, tra i vari formati di conversione abbiamo, MP4 con audio AAC o AVC con video H264 .

Il sito del progetto lo trovate qui: http://handbrake.m0k.org/

il software necessita per funzionare di installare diverse dipendenze eccovi le più importanti:


libavcodec (picture cropping, scaling and deinterlacing, MPEG-4 encoding)
libdvdcss (CSS decryption)
libdvdread (DVD navigation)
libfaac (AAC encoding)
lame-extras (MP3 encoding)
libmp4v2 (MP4 muxing)
libmpeg2 (MPEG-2 decoding)
libogg (OGM muxing)
libsamplerate (audio resampling)
libvorbis (Vorbis encoding)
libx264 (H264 encoding)
libxvidcore (MPEG-4 encoding)

installatele cercandole con synaptic ricordo che per ogni libreria dovete installare pure le librerie di sviluppo, quelle che finiscono con dev.
per scaricare il pacchetto aprite un terminale, digitate:

wget http://handbrake.m0k.org/rotation.php?file=HandBrake-0.9.1_i386.tar.gz

spostatelo dentro opt,scompattatelo.

sudo mv Handbrake* /opt
cd /opt
sudo tar zxvf HandBrake*

date i permessi al file HandBrakeCLI

sudo chmod a+rwx HandBrakeCLI

per agevolare l'utilizzo del software possiamo crearci un link simbolico, scriviamo da terminale:

cd
sudo ln -fs /opt/HandBrakeCLI /usr/bin

per convertire la struttura di un dvd in un file mp4 scriviamo.

HandBrakeCLI -i VIDEO_TS -o movie.mp4
