I spent the greater part of today adding remote control support to the Miro Fullscreen project. I thought I'd do a write up on it because there are a lot of pieces involved and it took me ages to figure it out and I'm paranoid I'll forget.
- I'm doing this on Ubuntu Intrepid (8.10). If you want to translate this to your favorite distribution, feel free to add any notes in the comments.
- If you're using OSX or Windows and want to know how to get things working there, I have no idea how to do it and that's not going to be covered here.
- I used a StreamZap remote and didn't try it with other remotes.
- This is a set of notes; it's not a good essay and I'm definitely not an expert.
I installed three packages:
sudo apt-get install lirc python-pylirc gnome-lirc-properties
lirc has a web-site at http://lirc.org/. I had no idea what I was looking at while wandering aimlessly through that site. I think the important pages are these:
- http://www.lirc.org/html/configure.html - covers the
- http://lirc.sourceforge.net/remotes/streamzap/lircd.conf.streamzap - covers the codes for the StreamZap; there are other code pages at http://lirc.sourceforge.net/remotes/
The only useful site I could find for this project was at http://pylirc.mccabe.nu/. It says that Paul Hummer took over the project and moved it to http://pylirc.ironlionsoftware.com/, but that's a dead link. I found Paul's blog at http://theironlion.net/blog/. He uses tagging on his blog, but there's only one article tagged as pylirc2 at http://theironlion.net/tag/pylirc2/. I couldn't find anything useful about pylirc, the project, its status, or what's going on. Paul suggests he was going to add LIRC support to Entertainer, but it doesn't look like he ever did that.
Anyhow, so I ended up going with the documentation on http://pylirc.mccabe.nu/ and that seemed to work out ok.
I don't know if I really needed
The .lircrc file
So you install the three (or two--depending on whether gnome-lirc-properties is really needed) packages and you create a
.lircrc file like this:
begin prog = mirofullscreen button = MUTE config = n end begin prog = mirofullscreen button = VOL_UP config = Up end begin prog = mirofullscreen button = VOL_DOWN config = Down end begin prog = mirofullscreen button = UP config = Up end ...
where prog is the string you pass to
pylirc.init, button comes from the remote control lirc file and config is the string you add handling for in your application.
the Python code
The sample code at http://pylirc.mccabe.nu/?/article/articleview/Documentation/1426&themex=public gave me enough of an idea on how it worked to implement the code in Miro Fullscreen.
Hope that's useful to someone at some point.
