Re: [GnomeMeeting-list] Re: current H.263 support

Hi,

Thanks for the quick response. I still, however, have some
questions:

I have done that. In addition I have read the details at

http://www.voxgratia.org/docs/h263_codec.html

When I put the openh323-1.15.3 in place with the FFMPEG
library and called the polycomm using gnomemeeting 1.2.1 the
polycomm reported it was receiving a H.261 stream.

So I moved the FFMPEG library out of the way and started
gnomemeeting again and saw the message

Cannot find libavcodec.so as required for RFC2190 H.263 video codec.
This function may appear to be installed, but will not operate correctly.
Please put the file libavcodec.so into one of the following directories:
 /usr/lib/pwlib
 This list of directories can be set using the PWLIBPLUGINDIR environment

This indicated to me that I did have things set up properly in
the first place. 

So I put he FFMPEG library back into place but still the
polycomm reports that gnomemeeting 1.2.1 is sending a H.261
stream.

So my questions are:

- can gnomemeeting 1.2.1 send a H.263 stream when
  openh323-1.15.3 is built with  
  
  ./configure --enable-rfc2190avcodec 

 and the FFMPEG library is in place?

- if so, can I force H.263?

- if not, will a newer version of gnomemeeting from CVS work?
  Can I force H.263?

Can I use the RPMS at

http://snapshots.seconix.com/redhat/fedora_core_3/i386/

It appears that the version in the snapshot wants opal:

[root oregano ~]# rpm -Uvh
gnomemeeting-snapshot-2005.07.08-CVS.i386.rpm
 error: Failed dependencies:
        libopal_linux_x86_r.so.2 is needed by gnomemeeting-snapshot-2005.07.08-CVS.i386
        libpt.so.1.9.1 is needed by gnomemeeting-snapshot-2005.07.08-CVS.i386
        opal >= 1.15.2 is needed by gnomemeeting-snapshot-2005.07.08-CVS.i386
        pwlib >= 1.8.3 is needed by gnomemeeting-snapshot-2005.07.08-CVS.i386

So does this mean that the RPM snapshot is the "opal" version
and will not have video support?

I would like to, but I need video. We are trying to use
Gnomemeeting with the VRVS reflector network to deliver
videoconferencing for a meeting. See

http://www.vrvs.org/

http://www.lsc-group.phys.uwm.edu/OSG/

If I can get it to work then I will have time after the
meeting to try out gnomemeeting-opal.

Cheers,

Scott
