[vdr] Generic input device / event support for VDR?
Has anyone tried to add support for the generic input device / event
interface to control VDR? This page for details of the input driver
support http://linuxconsole.sourceforge.net/input/input.html
The DVB card drivers send the commands from the IR remote to the event
layer and today these have to be translated into virutal key presses for
them to be picked up by VDR.
A new driver could be added to VDR to pick up these event directly,
without needing to go via the keyboard interface. This has the added
bonus that VDR doesn't need to be on the current tty to pick up the
events. Allowing you to change channels etc while using X or doing
something completely different on the terminal.
It also allows the control device to be a joystick, gamepad or anything
else supported by the input layer. In theory this makes the keyboard
driver redundant (although I think only linux-2.6 forces the keyboard to
go via the input layer).
I attached a driver which works for me. It is surprisingly easy to link
the event interface to VDR, most of the code is debug information taken
from the evtest.c example program which I used as a starting point.
Compile with "make REMOTE=EVENT" to activate this new input method &
remove your remote.conf file to get VDR to learn the new keys (assuming
you've already got your device generating input events).
