[icecast] Stream with Ices2 sound very metallic

Hi,

I don't know why, but the stream generated by ices sounds very metallic,
compared to the radio, and compared to a
stream of the same quality with darkice.

I tried different parameters, but it doesn't change.

My parameters are :
<input>
<module>oss</module>
<param name="rate">44100</param> <!-- samplerate -->
<param name="channels">2</param> <!-- number of
channels -->
<param name="device">/dev/dsp</param> <!-- audio device
-->
</input>
<instance>
                       
<reconnectdelay>3</reconnectdelay><reconnectattempts>9</reconnectattempts>
 <maxqueuelength>80</maxqueuelength>
 <encode>
         <quality>0</quality> <!-- for Full or partial VBR -->
         <samplerate>22050</samplerate>
         <channels>2</channels>
        <managed>1</managed> <!-- Full bitrate management -->
         <nominal-bitrate>30000</nominal-bitrate>
        
<minimum-bitrate>00000</minimum-bitrate><maximum-bitrate>30000</maximum-bitrate>
        
<minimum-bitrate>00000</minimum-bitrate><maximum-bitrate>30000</maximum-bitrate>
  </encode>
<downmix>0</downmix>
 <resample><in-rate>44100</in-rate><out-rate>22050</out-rate></resample>
<resample><in-rate>44100</in-rate><out-rate>22050</out-rate></resample>
</instance>

(only one resample line...)

I'm using all the  newer code from xiph.org cvs reepository.

(from last week)

Does someone has an idea ?

Thanks

This is extremely unlikely - if you're using the same settings with darkice,
it should sound the same (unless darkice is ignoring some of your settings), 
they both use precisely the same encoding library.

As a general note - setting maximum bitrate to the same as nominal is not a 
particularly good idea, it'll seriously hurt quality to do so.

I'm not sure this it the problem, because whatever the encoding if (managed
or not),
the problem is there.
To listen to the problem:
http://www.stalig.com/radio_ices.ogg	The ices stream in a file (a few seconds)
http://www.stalig.com/radiofree.ogg  	The darkice stream in a file (a few
seconds)

Looking at the content of the ogg files, we can see there are using the same
vorbis lib
even if i comment the bit rates and set the managed flag to 0, the problem is
there.

Strange...

[icecast] problem with make

i am trying to build icecast2 from cvs and make seems to be broken. 
it seems to be autogen'ing instead of making. I checked the code out 
tonight. 
 
I am running  
RH7.3  
make 3.79.1 
autoconf 2.5.3 
 
and I have been able to compile in the past but not on this machine. 
If anyone has any suggestions I would appreciate it. 
 
Thanks, 
 
jason

[icecast] Stream with Ices2 sound very metallic

Hi all,
in fact, I found that this feature is not implemented yet...

the vorbis setup returns : 
OV_EIMPL        The bitstream makes use of a feature not implemented in this 

<p>But, is it possible for the ices developpers to change
encode.c:encode_initialise
to display the vorbis return code?
        int ret = vorbis_encode_setup_managed(&s->vi, channels, rate,
                            max_br>0?max_br:-1, nom_br,
min_br>0?min_br:-1);

        if (ret) {
            LOG_ERROR6("Failed to configure managed encoding for "
                    "%d channel(s), at %d Hz, with bitrates %d max %d
"
                    "nominal, %d min. Error code=%d", channels, rate,
max_br, nom_br, min_br,ret);
            vorbis_info_clear(&s->vi);
            free(s);
            return NULL;
        }
    } else
    {
        int ret = vorbis_encode_setup_vbr(&s->vi, channels, rate,
quality*0.1);

        if (ret) {
            LOG_ERROR4("Failed to configure VBR encoding for %d channel(s),
"
                    "at %d Hz, quality level %f. Error code=%d",
channels, rate, quality,ret);

<p><p>It is helpfull. Then we may just need to add a function in
vorbis to display the error message
corresponding to the error code.
Perhaps I can do it, but I don't see how to apply as a developper.

What feature? This return value just means that the bitrate(s) or quality 
level you asked for is not supported at this sample rate/number of channels. 

Right now, none of those setup functions will ever return anything other than 
success or OV_EIMPL, so your proposed patch doesn't actually help (and also 
it wouldn't even compile, had you thought to test it).

There's no 'application process' to become a developer - you just
contribute
changes/improvements/fixes, and we incorporate them. If you do so enough, 
you'll generally be invited to become a core member of the development team.
