Myphone2 FPS problem
by ooi khai chin 15 Jan '10

15 Jan '10

Hi All, Currently, I found that when I start the myphone2 application (compiled from myphone2 source code), the settings->device(settings dialog box) can not change to my own driver name, it show Microsoft WDM Image Capture <Win32>. I run the myphone2 exe provided, it show me my own device is "Logitech QuickCamPro 4000". If I used my own compiled version, It only show me the 10fps during conference with the other. While if I used the myphone2 exe provided(able show device "Logitech qucikCamPro 4000"). It can achieve 25-30fps. It happen for any video codec (H.261, H.263, H.264). Anyone, What is the problem? Thanks.

Adding H263 codec to openmcu
by Michael Bondi 11 Jan '10

11 Jan '10

Hi all and Happy 2010! This may have been asked before, but I cannot help myself but to ask again. I have compiled ptlib 2.4.5 and h323plus 1.21 and openmcu 2.2.5 on a Debian 5 machine. I am able to connect and hear the tones and message for connecting but am unable to get video on the screen. I have tried compiling h323plus with only the 0.4.7 ffmpeg libavcodec.so placed in a directory /root/codec and compiled with ./configure --enable-rfc2190avcodec=/root/ffmpeg switch, all compiles fine, but still no h.263 video. Is there any more I need to do here? Also, I am getting confused where to unpack and install the a/v plugins from file http://www.h323plus.org/source/download/plugins-v1_21_0.tar.gz Thanks Mike

H264 PLUGIN in H323plus
by ooi khai chin 24 Dec '09

Hi All, In my situation, I have set my marker to 1 when it is the last partial frame, And it able to display on the remote endpoint every frame I sent. The problem is it just delay around 5s for all frame picture. Why? I already do some testing on my x264 encoder, it can encode frame with acceptable speed, So it wouldn't be encoder problem. Thanks.

Peer Element support in H323plus
by Hossein Aminaiee 13 Dec '09

13 Dec '09

Hi, We are trying to implement a gatekeeper with border element supported, such as the one in Tenor-Axx gatekeepers. I am curious to know whether it is supported by H323plus project or not. We have implemented the gatekeeper functionality with GnuGK and the platform is based on the latest version of Asterisk. Any advise is appreciated in advance. Thanks, Hossein Aminaiee

GPL awareness week
by Jan Willamowius 07 Dec '09

07 Dec '09

Hi, as most of you probably know, the GNU Gatekeeper is covered by the GNU Public license (GPL v2). Using GnuGk commercially is fine and it is also no problem to include it into commercial offerings as long as long as the proper credit is given and the modified source code is made available. Usually this works out fine, but sometimes a vendor needs a friendly reminder. So I would like to start a "GPL awareness week" where we all keep an open eye which products include the GNU Gatekeeper and check if they give credit and if the source code is available. I started a page to publish the code patches from vendors who bundle GnuGk at http://www.gnugk.org/gnugk-bundle.html If you know more applications that ship with GnuGk or have questions about the licensing details, please contact me off list. Let make sure everybody who uses GnuGk knows about it and enjoys the full benefits that the GPL guarantees! Regards, Jan -- Jan Willamowius, jan(a)willamowius.de, http://www.gnugk.org/

H264 PLUGIN in H323Plus
by ooi khai chin 07 Dec '09

Hi All, Currently, I would like to know how a NAL unit is organized inside an encoded data. Then, I read about the H.264 documentation, it mention about how to organize the NAL unit is outside of specification. So, anyone know any information or details on how the NAL organized? Thanks.

H264PLUGIN in H323plus
by ooi khai chin 02 Dec '09

Hi All, Currently, my H.264 encoded data is generated from hardware, not using software encoder libx264. And that hardware API only return me the whole encoded data buffer, and it's total size. So, is there anyway to extract, format the whole encoded data into NAL slice(less than 1.4KB) manually? Thanks.

H264 PLUGIN In H323Plus
by ooi khai chin 02 Dec '09

02 Dec '09

Hi All, I read about the RFC3984 for H.264, one of the type it can support is fragmentation Unit Mode(FU). In FU mode, the packet must add FU indicator(1 byte) and FU Header (1 byte). Indicator format F|NRI|TYPE Header format S|E|R|TYPE my question is why we need to include the NAL type twice in RTP packet of this (FU)mode? Thanks.
