Fwd: OpenMCU now supports up to 16CIF mixer
by Taranpreet Anand 27 Feb '08

27 Feb '08

Hi I have a sample application which supports QCIf, CIF and 4CIF. I have used it with the stable version of OpenMCU 2.2.3 which worked fine for CIF and QCIF. For 4CIF, I've downloaded the latest code from CVS. And as you have mentioned about altering the frameSize variable in the constructor of the OpenMCU class , I've done the requisite. OpenMCU::OpenMCU() : OpenMCUProcessAncestor(ProductInfo) { endpoint = NULL; #if OPENMCU_VIDEO frameSize = H323Capability::cif4MPI; #endif } But with this change, OpenMCU crashes as soon as the invitation for conferencing is sent out. The sample application works fine for 4CIF in case of peer to peer connection. Can you please help me out with this? Thanks Taranpreet Help save paper - do you need to print this email ?

H.pres status

Hi, One of the emerging standards that attracts me is H.presence - and I see from the 1.20.2 distribution of h323plus that the recent draft of AVD-3293 is included. However, whilst the code stubs are built by the parser, those stubs don't appear to be included when building the h323plus library. Adding their inclusion to src/Makefile in the H323_H460 section and rebuilding fails with what appear to be fundamental errors (copied at http://pastebin.ca/911251). Have I missed something obvious? I'm trying to build in an Ubuntu 7.10 environment with g++ 4.1.3. Also, I note that the stubs present in CVS under /extensions/h460/h460.presence are different from those bundled in h323lib-proper. Is there some magic documented somewhere that would enable me to build the testapp under the extensions tree? Sorry if this is all a bit "n00b"-like -- I'm new to h323plus. Feel free to kick me towards a readme somewhere that I most likely have missed! Thanks in advance for any input you can offer, Mark. -- "I don't care to belong to a club that accepts people like me as members" - Groucho

Runtime Optimized libraries

After looking in our beloved (hated by others) Wikipedia, in the link http://en.wikipedia.org/wiki/AMD_Performance_Library, I found that the AMD contributed to an open source version of the library, based on Apache License v2. So, for ones that *need* of an open source code (or want to learns about CPU intrinsics) instead of free use but closed souce (APL) see and contribute to the project http://framewave.sourceforge.net. I'll continue to port ptlib colours conversions and the h.323 video codecs to the APL version. After this I'll see if make the same to the Framewave version. PS.: I'm working to made the video split of OpenMCU a little more managed, in a week or two I'll send the files ;) -- ----- Jogue RPG, alimente o lado criativo!

OpenMCU now supports up to 16CIF mixer
by Simon Horne 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

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.

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.
