G.722 payload export to .wav

[umut orhan]

Hi all,

I hope that this is the right discussion list and sorry for possible inconveniences in advance.

I wonder whether the G.722 to .wav exporting is handled within the current wireshark release or is planned to be handled in near future. If not, do you think that a plugin or a feature for this issue is worth anything?

Best regards,
Umut

Hi,
The problem with codecs is that they might be patented or require
licenses to use.

Would it make sense to hand this off to an external player, e.g. VLC? It looks
like you can feed it RTP data:

Yes that might be interesting, another thougt is if it would be possible
to save Video and Voice in .3gp format and
Play it in Quicktime.

Hi,

as I know, G.722 has just expired patents and is freely available.

The C source code could be found in ITU-T G.191
http://www.itu.int/rec/T-REC-G.191/en

I am not 100% sure about licencing if we can use this source code in
Wireshark, it is why I have not released codec plugin with this G.722
codec.

Plugin source code (without ITU-T code) is attached.

Codec plugin mechanism is implemented just in RTP player. It is not used
in RTP saving now.

best regards,
Tomas

Here's the response I got to my query to licensing<at>fsf.org. Should we
ask to have it added to the queue?

Post by Kukosa, Tomas
Is there an opinion of the "free software" status of the "ITU-T software
tools General Public License"? I could not find it referred to in
http://www.fsf.org/licensing/licenses/index_html
An example of thie license is included as "Annex B" of "ITU-T G.191
SERIES G: TRANSMISSION SYSTEMS AND MEDIA, DIGITAL SYSTEMS AND NETWORKS
International telephone connections and circuits – Software tools for
transmission systems"

This appears to be nearly a copy of the GNU GPLv2 with "GNU" and "FSF"
replaced by "ITU-T", and with the patent provisions removed, and a few
other miscellanous changes. Is there anything on the ITU web site that
indicates their intent?

Anyway, my unofficial opinion is that it is a free software license that
is incompatible with the GNU GPL, since both are copylefts.

I can't render an official opinion and that would take *much* more study
by lawyers and others, so if you need that, all we can do is put it on
the list and get to it when possible.

Hope this helps. Best regards,
karl<at>gnu.org
