Compilazione stremdev

ricordatevi, siccome joomla tenta di evitare lo spam sulle caselle email e il comando cvs include un' email, dei tre pezzi in cui viene separata la riga, dovete copiare il primo ed il terzo, e scrivere a manina l' indirizzo mail, avendo cura di eliminare gli spazi prima e dopo l' indirizzo mail.

 :/var/cvsroot co streamdev
mv streamdev/ ./vdr/PLUGINS/src/streamdev/

nella dir /video creare le sottodirectory

mkdir /video/plugins

mkdir /video/plugins/streamdev

e dentro a quest' ultima creare un file col nome externremux.sh e renderlo eseguibile

touch /video/plugins/streamdev/externremux.sh

chmod ugo+x /video/plugins/streamdev/externremux.sh

nano /video/plugins/streamdev/externremux.sh

e dentro mettergli il codice

infine installare mencoder

apt-get install mencoder

siccome quasi sicuramente le cose non vanno mai per il verso che vogliamo noi, dovremo fare un po' di debug, specie se ci stiamo interessando alla transcodifica del flusso tramite externalremux.sh

quindi sara' meglio capire piu' approfonditamente cosa fa' il file externalremux.sh
