By default irsend take the default lircd configuration file. But irrecord save the recorded remote on a specific file :(
What I want to achieve is from a web interface launch the remote recording and once done be able to play a remote command with irsend by specifying the file where it was saved.
I'll have multiple remotes and don't want to take the irrecord file and merge it into the default lirc config.
On the doc http://www.lirc.org/html/irsend.html they say nothing about changing the file used.
