Hello, I have tried out lirc today with the remote control of my TV card. LIRC
is working fine, after some trial and error, then i wanted to test it on
mplayer.
Mplayer generally works with lirc, but it still has certain issues.
When starting up mplayer with lirc enabled, there initially comes following
message:
> Playing DieFabelhafteWeltDerAmelie.avi
> Cache fill: 0.00% (0 bytes) Error while reading cmd fd 5 : 2 = No such
> file or directory
> Error on cmd fd 5
> Detected AVI file format!
I haven't had a closer look on the mplayer, but I assume, that this error has
got nothing to do with the cache, but is being generated by another thread ;)
Well, that's only the first message, then the video loads up, everything
actually works fine, as it seems .. but in the background following message
is being created over and over again:
Error while reading cmd fd 5 : 0 = Success 2/ 2 0% 0% 0.0% 0 0 41%
Error on cmd fd 5
Error while reading cmd fd 5 : 0 = Success 3/ 3 0% 0% 0.0% 0 0 41%

And so on .. I think you get the idea. (I have modified the source code a bit
to also print out the errno and not only the corresponding string ... it is
located in input/input.c line 562 of the mplayer 0.90pre9 source code.)
I also fired up gdb and tried to collect some more data for you:

I hope this helps.
The commands i assigned are working, at least some .. that means seeking, mute
etc. works when i press the appropriate buttons on the remote control, the
only thing that also does not work is seeking backwards using lirc ... i
checked with "ircat mplayer" - there it is printing the correct command, and
seeking forwards works, just not backwards.
I doubt it is related with the problem at the top, but I apologize for not
doing any further research, my time is also very limited.
