While reading all of these IR threads another way of handling IR occurred to me that pretty much eliminates the need for LIRC and configuration files in default cases. The best way to make everything "just work" is to eliminate it. The first observation is that the IR profile of various devices are well known. Most devices profiles are in the published One-for-All database. These device profiles consist of vendor/device/command triplets. There is one triplet for each command like play, pause, 1, 2, 3, power, etc. The second observation is that universal remotes know how to generate commands for all of the common devices. Let's define evdev messages for IR than contain vendor/device/command triplets. I already posted code for doing that in my original patch set. These messages are generated from in-kernel code. Now add a small amount of code to MythTV, etc to act on these evdev messages. Default MythTV, etc to respond to the IR commands for a common DVR device. Program your universal remote to send the commands for this device. You're done. Everything will "just work" - no LIRC, no irrecord, no config files, no command mapping, etc. Of course there are details involved in making this work. MythTV will have to have a config option to allow it to emulate several different DVR devices so that you can pick one that you don't own. It should also have choices for emulating the common devices defined for the remotes included with various Linux video board like the Hauppauge remote. For apps that haven't been modified you will have to run a daemon which will capture vendor/device/command evdev events and convert them into keystroke commands than work the menus. You'll need a config file for this and have to write scripts. Instead I'd just go modify the app the respond to the IR events, it is easy to do. Long run, we define a MythTV IR profile, mplayer profile, etc and get these into the IR database for universal remotes. Now MythTV can stop emulating another vendor's device. For the default MythTV case no external support will need to be installed if the protocol decode engines are in the kernel. The raw data will come in, run through the engines, and pop out as evdev messages with a vendor/device/command triplet. Devices that decode in hardware will just send vendor/device/command triplets. -- Jon Smirl jonsmirl@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
