[MPlayer-users] Lirc issues - Mplayer 0.90pre9

[Thilo Schulz]

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%

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.
