[OT] New chan_h323 now Asterisk will not load
by Mark Best 17 Nov '09

17 Nov '09

First off sorry if this is a bit off topic. I've changed the Asterisk code from BOOL to PBoolean and chan_h323 compiles, but now Asterisk 1.6.0.17 crashes when I attempt to start it. There is no /var/log/asterisk/full log to check. I moved the chan_h323.so out of the /usr/lib/asterisk/modules/ folder, but it's still crashes. Anyone have any experience with this sort of thing? Does a different version of 1.6/1.4 work better than another?

H264 Plugin in H323plus
by ooi khai chin 17 Nov '09

17 Nov '09

Hi All, currently, I had been compiled the h264plugin from opal project, together with libx264,avcodec and any stuff to make it work. when, I do a conference on both side using my own codec in MyPhone2, It work fined. The problem occur when I communicate with other voip software like polycom, VCON... In the polycom(PVX 8.0.2) media statistic, it show both side info as below: People Tx People Rx ------------------------------------------------------- Video Protocol: H.264 H.264 Video Rate: 320 320 Video Rate Used: 319 84 Video Frame Rate: 15 0 Video Packet Lost: 0 0 Video jitter: 0 2 Video Format: QVGA ----- Audio Protocol: G.711U G.711A Audio Rate: 64 64 Audio Packets Lost: 0 0 Audio Jitter: 0 0 The frame rate and video format got problem... Do I need to specify video format and video frame rate in H323plus (generic capability), Any Idea??? Thanks.

Re: [h323plus] ast_h323.h:104: error: 'BOOL' has not been declared

First I tried a newer version of Ptlib. It appears Ptlib 2.7 isn't compatible with h323plus 1.21.0. I then tried Ptlib 2.6.6 which compiled with h323plus 1.21.0, but Asterisk still gave the 'BOOL' make error. I then moved forward to finding and replacing in the Asterisk code. Globally replacing the code didn't work, but finding and replacing just 'channels/h323/ast_h323.cxx' & 'channels/h323/ast_h323.h' seemed to do the trick.

H323plus v 1.22 and ptlib 2.6.5
by Sebastian Peschko 13 Nov '09

13 Nov '09

I wonder if someone can help out here. I am having trouble with Asterisk Crashes caused by libpt and openh323 where I am using Asterisk 1.6.2rc5 and h323plus v1.19.0Beta7 and ptlib v1.12.0. In this config when compiling the 2 packages and then doing a make in the asterisk H323 directory it automatically activates the chan_h323 in the Menuselect options of Asterisk and allows me to compile asterisk with h323plus support. The problem I am having is that I am registering with a Nortel H323 GateKeeper and when this looses the registry for some or other reason as a backup I send the calls using a Gateway directly to the Nortel PBX. With this configuration in v1.4.23 it was working perfecttly with openh323 v1.18.0 and pwlib v1.10.3. The problem came when because of issues with openmfcr2 I needed to upgrade to 1.6 for the embedded openr2 support. For this reason I am no trying to compile Asterisk 1.6.2.0rc5 with the latest h323plus v1.22.0 and ptlib 2.6.5. At the moment once these 2 packages are compiled it does not allow me to activate or select chan_h323 in the Asterisk "make menuselect". How can this be activated? I hope someone can help. Sebastian

Guys Just a quick note. http://www.packetizer.com/ipmc/h323/whatsnew_v7.html It has been nearly 3 years from my first submission to final approval on H.460.23/.24 but finally it's done. H.323 now has a standard complete NAT traversal solution. Simon

simph323 - could not open sound device

I am trying to get simph323 to work, but I having some trouble w/ the audio. Running h323plus-v1_21_0 with ptlib-2.4.5 on Linux.

Looking at ptlib/common/sound.cxx PSoundChannel it is baseChannel->PChannel::IsOpen() which returns FALSE For a quick test I changed the line to baseChannel->IsOpen() which makes it jump that hurdle and simph323 connects with the other h323 end and sound bits are exchanged. Here is the thing that puzzles me! I am using the same version of ptlib with opal (e.g. simpleopal) and don't see this problem. Code is build and run on the same machine. Any thoughts? mat

Opal H.264 plugin with OpenMCU and H323plus
by Prasad 06 Nov '09

06 Nov '09

Hi, I have taken latest code for ptlib, h323plus, avplugins from h323plus and H.264 plugin from opal. I manged to have video call on OpenMCU with H263. I found it has dependency on specific version of libavcoded, 0.4.7. For H264 I compiled the code and put the .so in $PWLIBPLUGINDIR, also I put libx264 in $LD_LIBRARY_PATH. But somehow H.264 codec is not getting loaded. The libraries are getting linked on start of openmcu but I cant see capabilities being added in OpenMCU traces. Is there any specific version of libx264 needed? I tried with version 78 and 67. Also, H264 requires avcoded too. Is this needed to be built with option --enable-libx264 ? -- Prasad
