Any news for armhf support of airtime?

Albert FR

do you talk about arm support ?

ktsouk

yes arm hard float

Albert FR

not for the moment
but you can try to install it with this (tiny) tutorial :

thanks for the info.

With 2.3.1 installed, the problem seems to be with the liquidsoap script and/or liquidsoap itself

airtime-liquidsoap start:

Starting Liquidsoap: Error in encoding format at

/usr/lib/airtime/pypo/bin/liquidsoap_scripts/ls_lib.liq, line 200, char 58-61:

quality should be in [(-0.2)..1].

Done.

Maybe Martin knows what to tweak.

Albert FR

what said yours logs files ?

ktsouk

Well i just changed the float numbers for the quality with 0 for the vorbis/ogg quality as a work-around.

I edited

/usr/lib/airtime/pypo/bin/liquidsoap_scripts/ls_lib.liq -> from line 200 (it is float numbers so i guess its liquidsoap :)

But 0 = 64 kb/s and 1 is 499kb/s(on bbb)

So, I guess I must find a way to output a 128kb/s ogg stream.

ktsouk

Well it seems the default value for vorbis/ogg is 112kb/s

Just edit /usr/lib/airtime/pypo/bin/liquidsoap_scripts/ls_lib.liq in lines 218 & 220 and erase the quality parameter.

(I will test some music and post back)

Albert FR

that's not my question

what said /var/log/airtime/... ?

ktsouk

I don't know to which log file of all /var/log/airtime/* you are referring to. Right now the /var/log/airtime/pypo-liquidsoap/ls_script.log says clock.wallclock_main:2] We must catchup n seconds! where n is n + ~0.25 every second.

And I never listened to any audio, except from noise from icecast2 (ogg-file=vorbis/ogg 64kb/s -> liquidsoap-output=mono vorbis/ogg 64kb/s).

Can one of these puppies ;)) generate the 1.21 gigawatts necessary to... encode two streams at once?

Howdy, Stranger!
