Posted: Fri Feb 12, 2010 3:39 pm Post subject: a couple of problems with IHU voip prog. |
|
|
just tested the IHU ebuild in the layman voip overlay. Perfect job.
This is exactly what I was looking for: a direct p2p phone connection. No skype , no server, no fees.
Works very well straight out of the box.
Two issues that may not be the fault of the software.
1/ I can only initiate the call from one end , this is probably due to broken firewall on router.
2/ A strong echo on one end (my end). Other direction is fine.
Very impressed.
The echo was present when I was test calling localhost and I took it to be the correct sound from the answering part of the the link. However, now on a remote call I am still getting my own voice strongly out of my audio output with about 0.25 seconds delay. Very distracting , but workable.
Anyone have any ideas on reducing the volume of the echo or why is it there at all ?

The echo turns out to be physical acoustic feedback. The other end is a laptop that needs quite a lot of mike gain to be audible. The speaker is nearer to the mike than the users head so some feedback is to expected.
The echo time is basically twice the latency of the link. This is less using UDP, more if only using TCP link. _________________ Linux, because I'd rather own a free OS than steal one that's not worth paying for.

How did you do? It seems to need qt3. I get this error when emerging on amd64: Code: | checking for Qt... ls: cannot access /lib/libqt*: No such file or directory
ls: cannot access /usr/lib/libqt*: No such file or directory
ls: cannot access /usr/local/lib/libqt*: No such file or directory
ls: cannot access /opt/lib/libqt*: No such file or directory
ls: cannot access /usr/lib/qt4/libqt*: No such file or directory
no
configure: error: QT LIBRARIES NOT FOUND. They might be in a non-standard path (then use --with-Qt-dir option), or they need to be installed. |
Thanks for the hint anyhow. _________________ Mandrake Dec 2001 · Debian "Woody" Aug 2002 · Gentoo Jan 2004 · Funtoo Oct 2009 |

did not do anything special , just used the overlay.
Code: | [ebuild R ] net-im/ihu-0.6.0 USE="-jack" 0 kB [1]
|
however I seems to have qt3 installed from an overlay.
Code: | etcat -v qt
* x11-libs/qt :
[M I] 3.3.8b-r2 (3) OVERLAY
[M ] 4.5.3 (4)
[M~ ] 4.6.1 (4)
[M ] 4.6.2 (4)
-su-4.0#

I guess that is from the voip overlay I stated.
