I would like to remotely control the volume (vol+, vol- and mute) of embedded Adobe Flash players (BBC iPlayer, youTube).  In Windows I can do that by sending the Hauppauge Irremote.ini commands {app(0xa0000)} {app(0x90000)} and {app(0x80000)} respectively.  How can this be done in Linux using lirc?  Pls advice.
