H264PLUGIN in H323plus
by ooi khai chin 02 Dec '09

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.

missing RTP Frames
by Igor Pavlov 27 Nov '09

27 Nov '09

Hello. I missing RTP frames, when connect with my H264 plugin on connection speed greater then approximately 256 kBps. I inserted logging of rtp frames sequencenumber in function RTP_Session::SendReceiveStatus RTP_UDP::ReadDataPDU(RTP_DataFrame & frame); after call SendReceiveStatus status = ReadDataOrControlPDU(*dataSocket, frame, TRUE); and periodicaly I have holes in sequence of numbers. At the same time I have working sniffer, and I see that RTP packet missing in my logs is present in sniffers statistics. I tryed to find the place in h323plus sources where can I miss RTP packets, but couldn't find it :( The missed group of packets (even if length of group is 1 - single packet) always ends with rtp packet which have marker=0 Help me to find out the reason why I missing packets. Because of speed?

H264 Plugin in H323Plus
by ooi khai chin 24 Nov '09

24 Nov '09

Hi All, regarding the H.241 documentation, it mention that H.264 plugin in H.323 only support single NAL mode. Then, I refer the RFC 3984, it state that single NAL mode only support type 1-23 NAL unit, no FU-A, no FU-B, ... Currently, I am using H.264 hardware encoder which used baseline profile, not libx264. My H.264 encoder(hardware) will only return the whole encoded data and it's total length, not each NAL and it's length. So, how can I make it comply to H.323 if no fragmentation is allowed in H.323? Thanks.

H264 PLUGIN in h323plus
by ooi khai chin 24 Nov '09

24 Nov '09

Hi All, For the libx264, It directly fragment the encoded data if it larger than the maxpayloadsize (1.4KB by default). If I had encoded data 5.6K. Then, it will fragment and sent out, 4 times. Is it comply to H.323 standard? Because currently other voip (polycom, Mirial...) can't display my encoded data size greater than 1.4K. Thanks.

H264 PLUGIN in H323Plus
by ooi khai chin 24 Nov '09

24 Nov '09

Hi All, Currently, my H264 plugin able to work with polycom. I found that the media statistic(polycom PVX ) only show the frame rate video format, and display the image if my sending encoded data is not more than 1.4KB. In my code, I do the fragmentation once it greater than 1.4KB(like libx264 do). However, I had read some documentations and all of them mentioned about H.241 only support the single NAL unit mode(mode 0). I wonder how this mode handle if encoded data greater than 1.4KB(usually happen)??? Any Idea? Thanks.

H264 PLUGIN in H323Plus
by ooi khai chin 23 Nov '09

23 Nov '09

Hi All, I captured the capability exchange from difference voip software like(polycom, vcon...), it show only "0.0.8.241.0.0.1", which is defined as OpalPluginCodec_Identifier_H264_Generic. 1. What is the difference with the others like (default, RFC3984 interleave, RFC3984 non interleave)? Another things is that When I use my H.264 Encoder API, it only return me the encoded data and the encoded length. 2. So, is it considered as single NAL unit? How it can be comply to H.323 since the default MTU value in H.323 is 1400bytes (like fragmentation or other)? I try to increate the MTU value, but it cause me error.

Re: [h323plus] [Openh323gk-users] PTLIB PASN_BMPString handling changes and endpoint not registered.
by Simon Horne 18 Nov '09

18 Nov '09

Guys I need to make you aware of a change that causes different registration endpoint identifier lengths to be generated based on the version of ptlib used. GnuGK 2.3.0 (ptlib 2.4.5) registrationConfirm { ... endpointIdentifier = 9 characters { 0034 0033 0039 0035 005f 0065 006e 0064 4395_end 0070 p } GnuGk 2.3.1 (ptlib cvs) registrationConfirm { ... endpointIdentifier = 10 characters { 0034 0033 0039 0035 005f 0065 006e 0064 4395_end 0070 0000 p } While this may not look too much of a problem however if you are registering a h323plus endpoint built off a later version of PTLIB (like PacPhone) on a GnuGk with an earlier version of PTLIB then your endpoint will register but will not be able to make any calls and you will get an error about endpoint not registered. This is because the gatekeeper generated a 9 character endpointIdentifer while the endpoint will send a 10 digit identifier to the gatekeeper. I have patched the latest PacPhone preRelease to resolve the problem www.pacphone.com/downloads/PacPhoneSetup230.exe I will be applying a fix to the H323plus CVS shortly. Simon

[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
by Mark Best 16 Nov '09

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

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
