Craig I missed this...Wow! Sorry I must of missed typed. Sorry openh323. H323plus uses much of the same code base and front end api ie H323EndPoint::OpenVideoChannel (which was the context of the comment) etc as openh323. Existing OpenH323 applications like YATE and GnuGk still work with h323plus. Opal interface has evolved differently over time. It is true h323plus plugin video api has its roots in Opal which were ported over a few years ago. For sometime after that the api's were identical which I helped maintain but things deviated over time. It happens. There was no malice or inference intended. Don't think for one minute I'm claiming anything over anything. In 2007 a decision was made that forced a split in the develop paths (and ultimate demise) of OpenH323. A group of developers went a different path and few chose another direction. We all come from the same origins. OpenH323... Sorry Craig if there was any claim or inference it was not intended. You kept OpenH323 alive for many years and both communities should be very thankful of the tremendous effort you put in sometimes in the most difficult of circumstances I'm certainly am sorry for my poor judgment in wording offended.

Opal and H323Plus both derive from OpenH323. Any claims to the contrary are a mistake or flamebait. On the subject of video plugins, Opal had video plugins before either OpenH323 or H323Plus. I know this because I wrote the code in Opal to support a customer who paid for it. The H323Plus developers chose to make their video plugins similar to Opal, but not the same. I imagine this is because they chose their own development path from the original OpenH323 code base, rather deriving from the already extant Opal design. In any case, the video codec plugin work in H323Plus appeared after the corresponding Opal code had already been deployed, so any claim that Opal was derived from H323Plus even in this specific area are not supported by the evidence.

unavailable H.264 plugin and missing H.263 CIF4/16 capabilities
by Vladimir Fekete 24 Feb '11

24 Feb '11

Hello Simon, few days ago, you told us you confirm, that H.264 works (with h.239) for H323plus project. I was able to compile x264, ffmpeg and the plugin itself, however, when I put it into correct directory with all the dll files, none of the example applications can see it (but they see for example h261vic plugin located in the same directory as h264 plugin). I also tried to use trace (with application 'simple') and I see that capabilities are loaded, but not the H.264. MSVC says for debug version of myphonet, that the symbols from h264 dll were loaded and dll is in use (did not say what symbols). Hence I'd like to ask you - the file plugin-config.h which is located in two directory above H.264 project (as plugin-config.h.in) was changed to proper header file by ./configure command or you changed (created) it by hand ?(for windows) (my suspicion is, that symbols are not properly exported from the dll, but I don't know how to verify it) - are you aware of any reason why properly compiled h.264 dll and helper would not work with recent h323plus and ptlib ? I'm obviously missing something and I really would like to make it run (with h323plus for start and in the end with OPAL) To all, yes, you were right, the H.263 distortions and damage I saw are "problem" of OPAL, since h323plus myphone2 has no problem with it and I can see nice H.263 CIF picture. However, and this is true for opal and h323 plus, I'm unable to use higher resolutions e.g. CIF4, CIF16 and the custom one (capability for it is missing). So I'd like to ask : - is h323plus or OPAL capable of CIF4 and CIF16 with given codec(s) 263/264? (e.g. without necessity to drastically change the code), if so, could you, please, point me to any hint how to make it run (lines of code with comment, anything) - when we can expect OPAL will transform the h.263 and h.264 to it's plugin format ? (I would do it by myself, but first I have to see it running with h323plus, so I get time to look at the plugin format of opal and how to do it - unless some good soul wont outrun me) Many thanks ! Best regards, Vladimir Fekete

Robert Older cheaper webcams really behavior quite poorly. For instance 1. They support formats which only can be transformed to RGB24 (and nothing else) in DirectShow filters so then with good webcams you have to filter out and only use the formats that are known to transform to RGB24. (When it all should just work with YUV so there is no need to convert in PTLIB) 2. a couple I have seen supply undersize (or corrupt) image buffer when starting up hence why the directshow output device automatically throws the first few frames away. 3. They fall over when trying to set a video frame size within the camera limits but not exactly as they support. So you are limited to exact sizes. ie like 4CIF. Some webcam may support sizes above 4CIF but not 4CIF exactly (quite common). Some webcams you can adjust the output pin to get the size others the video will just simply fail without any warning. This is why the PVideoInputDevice::GetDeviceCapabilities was introduced so with the plugin you could choose a video size/rate the webcam did support thereby avoiding having to scale/crop etc. Thankfully the latest generation of webcams perform much better like the Microsoft LifeCam Cinema which gives reliable 720p@30 or the new Logitech C910 which provides 1080p@30 (with USB3) with the current DirectShow driver in PTLIB. But still we need to support these older webcams without hardcoding or maintaining a bad list.

Modifying Q.931 IEs in setup PDU
by Paul Chitescu 23 Feb '11

23 Feb '11

Hello all! While trying to add code in Yate to set some important parameters - for the telephony business - I noticed my changes are overwritten by OpenH323 / H323Plus. I reimplemented H323Connection::OnSendSignalSetup() and changed the Q.931 fields in setupPDU. Unfortunately the following code (in h323.cxx) undoes my changes: if (!OnSendSignalSetup(setupPDU)) return EndedByNoAccept; // Do this again (was done when PDU was constructed) in case // OnSendSignalSetup() changed something. setupPDU.SetQ931Fields(*this, TRUE); setupPDU.GetQ931().GetCalledPartyNumber(remotePartyNumber); Is there any solid reason why setupPDU.SetQ931Fields(*this, TRUE) is called? Its default parameters are overwriting the type, plan, presentation and screening of the numbers. I also need to set separate type of number on caller and called party numbers. My plan is to patch OpenH323 / H323Plus to delete the extra SetQ931Fields(). Do you see any unintended consequences of such a change? Regards, Paul Chitescu

Re: [h323plus] [Opalvoip-devel] error H.263
by Simon Horne 22 Feb '11

Jan You are correct . To match to a bandwidth the encoder must know frame size and rate. The plugin support is very much h323plus specific. You can calculate the frame size/rate by using the internal table or can use a supplied list of supported frame sizes/rates. These can be manually coded from largest to smallest or retrieved from the video input device. DirectShow for instance supports retrieving the list of supported sizes and rates via calling PVideoInputDevice:: GetDeviceCapabilities(). These can be passed to the codec via calling PLUGINCODEC_CONTROL_SET_FORMAT_OPTIONS. In h323plus the function to do this is H323VideoCodec::SetSupportedFormats. The function returns the default frame size and rate for the given bitrate that is supported by the input device. Then you can set the input device with the returned frame size /rate in the MyH323Endpoint::OpenVideoChannel. See Applications/SimplePlus for example of how that is done. The bandwidth (and level\MBPS etc) values for the X264 Encoder is set by PLUGINCODEC_CONTROL_SET_CODEC_OPTIONS which is called after the local and remote capabilities have been merged in h323plus. Then there is flowControl which does basically the same thing. You pass to the plugin a bitrate value via PLUGINCODEC_CONTROL_FLOW_OPTIONS it then returns a supported frame size/rate (internal or supplied earlier) then you pass these value to the input device via calling PVideoInputDevice:: FlowControl(). The architecture of Opal has deviated a lot from its h323plus roots and I think there is a lot more things to consider to getting this to work with it.

Re: [h323plus] error H.263
by Vladimir Fekete 14 Feb '11

14 Feb '11

Hello Robert, 1) I went directly to plugins/video/H.263 ffmpeg/ directory (after I compiled ptlib and opal) 2) downloaded http://www.voxgratia.org/bin/libavcodec-0.4.7-windows.bin.zip as is written in readme file and unzipped it into plugins/video/H.263 ffmpeg/ffmpeg 3) I've opened the 'h263ffmpeg_2005.vcxproj' file and saved solution which VS2010 created for this project 4) Build it 5) No errors - result is ../../Debug/h263ffmpeg_pwplugin.dll (and the rest things such as .pdb file) Best regards, Vladimir P.S> this is resubmitted, because last time I just replied to Robert and did not used the other addresses as well. Sorry about that.

lost rtp packets and using jitter for video session
by Igor Pavlov 08 Feb '11

08 Feb '11

Hi, On connection speed greater than 384 kbps I have many lost rtp packets. If I switch off decoding of incoming video packets, than number of lost packets decreases. That is why I would like to try use jitter on video stream. I changed call of OpalMediaFormat() constructor inside OpalVideoFormat constructor in such way that needsjitter member become TRUE. But It is not working, not decoding any data. How can I use Jitter for my purpose and in general - can I do it? Igor Pavlov
