Hi,
This is why I thought of this "hack" using on_end... it would not guarantee
that there is no more non-blank afterward, but if there's a blank during,
say, the last 5 seconds of a file, it is likely we can safely eat it and
won't lose much. So I was thinking of something like :
output = on_end(5.,[eat_blank(source)], source)
But I don't know if on_end works that way, and can't figure out a working
syntax for on_end. If I try it the way described above, I get the following
error :
At line 61, char 18-19:
this value has type
float
but it should be a subtype of
(_,_)->_
I don't even know what's "a subtype of (_._)->_".
Of course in any case this would mean a 30 second blank at the end of a file
wouldn't be eaten, but such a case is unlikely to happen.
So do you think on_end could be used to limit the time of a track during
which a processing is in effect ? And if yes, how should I write the line ?
(Using 1.0.0-beta+svn (trunk/liquidsoap@rev8237) if that can help).
Azrael.
