Abbiamo rilasciato la versione 1.0.2 di RAISMTH che fissa alcuni bug segnalati dagli utilizzatori, tra i quali il supporto per i proxy http
Download: https://addons.mozilla.org/it/firefox/addon/raismth/

L'estensione adesso legge le impostazioni proxy di FF e nel caso sia specificato un proxy HTTP,
crea la variabile d'ambiente http_proxy che viene interrogata da mplayer all'avvio dello stream.

Ovviamente per riuscire a vedere qualcosa, è necessario che il proxy server sia "prestante" e configurato correttamente!
Nei test effettuati utilizzando un proxy server gentilmente messo a disposizione da kowalsky, un transparent proxy senza particolari configurazioni,
è stato possibile visualizzare sia i canali mms che quelli smooth, con ottime prestazioni.

Di seguito alcuni test effettuati con altri proxy servers IT:

PROXY SRV IP     PORT   SMTH OK         MMS OK  STATO
217.19.149.213   3128   ok smth         ko mms  veloce
80.22.33.138     8080   ok smth         ko mms  lento
195.96.159.36    8080   ok smth         ko mms  veloce
89.188.136.116     80   ko smth         ko mms  veloce
151.12.58.204      80   ok smth         ko mms  veloce

Come si può vedere nessuno dei proxy servers testati lascia passare il traffico mms..mentre con quasi tutti funziona lo smooth streaming..

Di seguito un estratto dei logs dell'ext ottenuti abilitando l'opzione debug e utilizzando il proxy server http://151.12.58.204:80
