Re: [Savonet-users] Getting liquidsoap to output using external aacplusenc + using several harbors

Hi,

Thanks, your two examples worked great.

But I discovered two more problems now.

1) I used to have a crossfade after a rotate() for music and jingles
but before any switch or live, and it used to work. But now, I get an
error :
Error when initializing source at line 99 char 15 - line 102 char 2:
cannot unify two dependent clocks: cross_5074[],
?(5b85c5ee:0)[cross_5074[]].
However, it does work if I put my crossfade BEFORE the rotate, that is
to say, when it has to crossfade between tracks of only one playlist.

Here is a code sample :
radio = crossfade(start_next=0.7, fade_in=0.2, fade_out=0.2,musique)
radio = rotate(weights=[2,1],[radio,jingles])
This works.

radio = rotate(weights=[2,1],[musique,jingles])
radio = crossfade(start_next=0.7, fade_in=0.2, fade_out=0.2,radio)
This gives the error.


Also, I noticed that if I have, say :
playlist_1 = rotate(weights=[2,1],[musique,jingles])
playlist_1 = crossfade(start_next=0.7, fade_in=0.2, fade_out=0.2,playlist_1)
playlist_2 = rotate(weights=[2,1],[musique2,jingles])
playlist_2 = crossfade(start_next=0.5, fade_in=0.2, fade_out=1.0, playlist_2)
This gives another error, : "an operator cannot belong to two clocks."

I guess that this is because I can't reuse the source "jingles" in two
different crossfades... but how do I bypass this problem ? I've
thought of having the following :
jingles2 = jingles
playlist_2 = rotate(weights=[2,1],[musique2,jingles2])
playlist_2 = crossfade(start_next=0.5, fade_in=0.2, fade_out=1.0, playlist_2)
But this fails with the same error.

Am I forced to have the following ?
jingles = playlist(jingles.m3u)
jingles2 = playlist(jingles.m3u)


Also, these two playlists are for a switch, so I've thought of putting
the crossfade AFTER the switch... then I have no error, but liquidsoap
falls back to my "security" file (I have a fallback like
fallback([live, playlist, security]), as if the playlist became
suddenly unavailable...


OK, this was just the first problem.

The second one is even more problematic, but easier to explain : i

In my playlists, I have a bunch of m4a files, but although I compiled
liquidsoap with faac/faad support, m4a files are handled by mad, who
fails at efficiently playing them, just passing to liq a short
high-pitched audio glitch (sounds awful). I think the problem also
happens with live sources (shoutcast with aac+ sent to a harbor). How
should I avoid this ?
