Re: [h323plus] MyPhone 0.4 Released

Hi,

I've downloaded the latest version of the plugin codecs from the CVS, and I've seen that the frames are being grabbed at 10 fps. Additional testing has showed me that the problem seems to be with the following line of code, in CMyPhoneEndPoint::OpenVideoChannel: codec.SetMaxBitRate(videoBitRate * 1024);

I think that the problem is that codec is an instance of H323VideoCodec, and the implementation of H323VideoCodec::SetMaxBitRate does nothing but an assignment. I think that what it should be called is H323PluginVideoCodec::SetMaxBitRate, which is in fact a descendant of H323VideoCodec. I've tried to do a cast from H323VideoCodec to H323PluginVideoCodec, but I get compilation erros due to the undefined class H323PluginVideoCodec, because in fact it is defined in a *.cxx file, not a *.h.

Am I correct? Or am I missing something?

Best regards,

This is strange. The bitrate is sent to the plugin codec. What codec are you using? what version of h323plus and how old is your video plugin? I updated the H.263 plugin about a month or so ago, prior to that it just ignored these settings so that might be the problem.

From the tracefile make sure the video frames are being grabbed at the right fps (for 10 fps every 100ms)

Hi, Simon:

I've downloaded the latest CVS code with the support for bitrate, fps and Adaptive packet delay. But it seems that MyPhone2 is not using the settings. Let me explain this:

1. I've configured the following vlues for video:

fps = 10, Maxbitrate =50 kbit/s. and quality = 15. Size = QCIF. 2. If I capture the video packets with Wireskark, I can see that the bitrate is about 300kbit/s.

Where is the problem? Am I missing any additional setup?

Best regards,

 looks like you are right. I have added support for bitrate, fps and also adaptive packet delay to the CVS.

Hi,

I'v been looking at MyPhone2 0.4 source code,

and I was wondering how is the videobitrate, fps, etc... managed, because I've seen that all of this parameters are read from the configuration, but they are never used.

Best regards,

Guys

I have uploaded MyPhone 0.4 installer to the

h323plus website to garnish some feedback on the upcoming 1.20 release on h323plus. Download here

http://www.h323plus.org/source/download/MyPhoneSetup04.exe

(2.12Mb)

Important Features
Native NAT traversal with GnuGk : This uses the

new GnuGk NAT module now in H323plus. You can send and receive calls behind a NAT when registered to GnuGk on the public internet. The only requirement is that you enable SupportNatedEndpoints in GnuGk. Note this is the GnuGk NAT Method http://www.gnugk.org/nat-traversal.html. It is not the standard H.460.18/19.

Built off the latest h323plus CVS. (hopefully

the baseline for v1.20)

Notes:
To run in debug mode start myphone with

commandline switches -ttttt (number of t indicate tracelevel) After Install adjust the audio and video codecs to your preferred order. G.711 & H.261 are the default.

The installer contains the full myphone2 source

code. The exe was built with vs2003. If you wish to build it with a later version of visual studio, although not tested, you will need the $ version as the express version does not seem to support MFC.

Hopefully next week if there are not too many

problems we will do the snapshot and release v1.20.

Simon
