Hi Salvatore,<br>
<br>
VLC is ok, the problem is that you are not using it for what it was
designed for, video streaming has nothing to do with real time
communications.<br>
<br>
You can try to get better results by tweaking the following ffmpeg
parameters in vlc for H263:<br>
<br>
<ul>
<li> <b>qmin=<quantizer></b> allows to set the minimum
quantizer scale;
</li>
<li> <b>qmax=<quantizer></b> allows to set the maximum
quantizer scale;
</li>
<li> <b>qscale=<quantizer scale></b> allows to specify a fixed
quantizer scale for VBR encodings;
</li>
<li> <b>i-quant-factor=<quantization factor></b> allows to set
the quantization factor of I frames, compared to P frames;
</li>
</ul>
Set qmin=qmax=qscale=31 and <b>i-quant-factor=1 </b>to get the
minimum quality possible (and minimum bandwidth). Anyway, using VLC you
are going to get a much lower quality compared with an encoder prepared
for CBR and RTC. <br>
<br>
Best regards<br>

Yes, I know the vb parameter can set the video bandwidth but it doesn't
work. If I change vb then I capture the packets from Wireshark the
total video bandwidth doesn't change. I think that there is a problem
with VLC.<br>
My question: is if possible that a video of 1.25 Mbits without
compression will reduced to 350 Kbits mean value with a peaks of 500
Kbits (H263p codec)?I think that value is too high...<br>
<br>
The video bandwidth of eyebeam, bria or ekiga is lower than VLC
although the softphones send animated video. <br>
<br>
Thank<br>
