OpenMCU now supports up to 16CIF mixer
by Simon Horne 19 Feb '08

19 Feb '08

To all OpenMCU now supports either CIF, 4CIF or 16CIF video mixer. This means if endpoints are about to support HD and large frame sizes then they can send and receive at those frame sizes with the MCU with H.263. By default it is still CIF but you can change the size by altering the frameSize variable in the constructor of the OpenMCU class. Simon

Optmized version os libs
by Marcos Fábio Jardini 18 Feb '08

18 Feb '08

To not spend work in reinventing the wheel I want to know if there are people working in the codecs and PColourConverter classes using the AMD Performance Library. AMD is providing the APL lib in Linux, Windows and Solaris flavours, and they version of GNU GCC 4 for RH and SuSe. (http://developer.amd.com) I'm woking in a project for use in internet2, so I'll 'spend' some time in create of a RAW YVU420 codec, but reading the APL manuals they provide suport for H.264 :). If some have interest or already in the same effort.... If someone already have a RAW codec or already using the APL please can share some hints on sourceforge forums of this project, I'll be pleased. Other question I have is how to add the H.263 video capability in H323Plus, I'm new to the H.323 and openH323 implementation and I am a bit lost with the modifications in H323plus. ** When the work is done I'll ask to put the code or the link it to the internet (it's a project sponsored by the government for a public university so, I think I'll have no problems in sharing the codes produced/modified) -----

Ok, but what if I want to set, for example, qcifMPI to another value?? Is it possible? BTW, have you got any idea of what it is going wrong with the video bandwidth management? As I said before, I can send you Wireshark traces, if you need them.

H.460.18/19 support now in h323plus
by Simon Horne 12 Feb '08

12 Feb '08

Guys Just a quick note H.460.18/19 client support has now been added to h323plus. The source code and a very basic sample app have been added to the extensions/h460 directory in the CVS http://h323plus.cvs.sourceforge.net/h323plus/extensions/h460/h460.18/ It compiles with h323plus v1.20.1 available from the h323plus website and has been tested against Tandberg gatekeepers. Both GnuGk (default) and H.460.18/19 NAT methods work without conflict so you should be able to support both the standard H.460.18/19 and the GnuGk methods in your applications without any problems.

Simon, Maybe the problem is that the funtionality that was implemented in the old H323_H263Codec::Read() method has gone away, isn't it? It seems that in that code was implemented the adaptivepacketdelay feature. Is right? ----- Mensaje original ---- De: Simon Horne <s.horne(a)packetizer.com> Para: JF NP <jfnp090274(a)yahoo.es>; H323plus <h323plus(a)lists.packetizer.com> Enviado: martes, 12 de febrero, 2008 10:44:16 Asunto: RE: [h323plus] MyPhone 0.4 Released DIV { MARGIN:0px;} If memory serves me right the openH323 version never handled I-Frames.

If I don´t move the camera, it sends about 50 kbps (the configured video bandwidth), but if I move the camera, to force sending I-Frames, the bandwidth increases until reaches more than twice the configured bandwidth. The same test works fine with the previous version of openh323 and MyPhone. What's happening? If you need them, I can send you Ethereal traces.

This function also overrides H323VideoCodec::SetMaxBitRate() since H323PluginVideoCodec is a descendent of H323VideoCodec so the problem most likely is in the plugin codec not setting the max bit rate. I suggest you look at the H.263 plugin codec perhaps there is something missing.
