Justin,
I'm not a linux guy, or a that well versed on ICES, but, I went thru the
code (stream.c) and just kinda nosed around the broadcast part. When we
look at distros that this uses, it may be the correct version of the
package, but it might actually be a supporting package, like curl or
something like that. If you look at the code attached below, it shows there
might be some kind of memory leak that needs to be taken care of. This is
in the sdsc stream description, which if I'm right, uses shout. (#include
<shout/shout.h>)
Maybe the error you're finding is because you have special chars, or bad
chars, and the version of shout you're using isn't right. When I look at
the code below (sorry, can't read machine language to guess what you put
into pastebin). Have you taken a chance to set your logging to a high level
to see what the error log says? That may shed some light as to what the
error could be.
But if you go thru the log and check out the errors, and then go back and
look at the stream.c file that's included in the source, you could search on
the error code, find where it's blowing up, and then try to figure out what
library it's using when it does. There may be a different version of that
library for each different processor.
if(encoding)
{
if(inmod->metadata_update)
inmod->metadata_update(inmod->internal, &sdsc->vc);
sdsc->enc = encode_initialise(stream->channels, stream->samplerate,
stream->managed, stream->min_br, stream->nom_br,
stream->max_br,
stream->quality, &sdsc->vc);
if(!sdsc->enc) {
LOG_ERROR0("Failed to configure encoder");
stream->died = 1;
shout_free (sdsc->shout);
sdsc->shout = NULL;
return NULL; /* FIXME: probably leaking some memory here */
}
sdsc->enc->max_samples_ppage = sdsc->stream->max_samples_ppage;
}

Hey All,
Happy New Year! I have a question regarding EZStream for Windows. I saw in
one of the examples, I could use a script, such as a playlist.pl. Is it
possible to use a custom .exe file, or a vbs/wsh script instead?
Thanks,
Doc

Hi all,
I was really hoping to get a bit of help from this. I've since gone to
ezstream to try and accomplish the same goal, but ices2 is so simple to use
I would really like to stay with that instead.
Can anyone help me debug this memory leak? I can't use valgrind to try and
debug because it throws an "Illegal Instruction" whenever I try to run it.
:(
Happy New Year!
