Need help with cross-compiled pianobar

seaniko7 · 10-21-2011, 12:06 AM

I've managed to cross-compile pianobar for Kindle 3, but I need some support with ALSA stuff.

When it begins to stream music :

Quote:

ALSA lib pcm.c:2014:(snd_pcm_open_conf) Invalid type for PCM front definition (id: front, value: cards.pcm.front)
ao_alsa WARNING: Unable to open surround playback. Trying default device...

message appears; sound is messy. It plays for about 5 sec and then it shows read/write error.

I would be very grateful if somebody helped me. :)

Ok, I got rid of error messages by updating ALSA libraries and utils.

Sadly it's still crackling.

I think the Kindle was a bit picky about sample rates. It needs some certain ones. I don't know pianobar enough, however, to give tipps how to use certain ones.

I tried to get pianobar to work as well, try "nice -n10 pianobar"

i got better success that way

As I recall, K3's do that, its a built-in feature.

Build and run on one of your K5s - you should have better luck.

Nearly all of the audio/video stuff twobob did was for the K5 (for just this reason).

OK, I'm still working on it. I can run it from ssh but I want to be able to run it from kterm - so I'm working on that. Also there are some warnings about undefined symbols... BUT I can login and hear music.

My setup in case you are curious:
I have a partition on my laptop with debian ARM & qemu so I can chroot into it.
This way I can apt-get anything debian has, including source or just git tools or whatever.
Then I compile the program using the readme or whatever...
Then I have a script that packages it with the dependent libraries.
I then move it to the Kindle and ssh in and try it.

This program is weird because it calls for ffmpeg libraries that I tried to build but after 6 hours I gave up so I found a hint about using wheezy-backports for the libraries instead. Then pianobar built in like 20 seconds. Still working on the whole package.

edit: posted a working file in the other thread.
