You build the plugin codecs in the plugin directory. They are separate files. Look for *_ptplugin.so

Apply this patch

Hi,

      I have found that v4l2 plugin is already built.And I have used the variable PTLIBPLUGINDIR to point it to the directory containing plugin.
But still, I am unable to get Video transfers.
When I started debugging, I found that the simph323 application program flow is being hanged up at the function call
PVideoInputDevice::GetDeviceCapabilities(devices[0],inputDriverName,&caps) 
in main.cxx file.
Can you please help me in giving correct options while executing the application.
or any other suggestions to get Video transfers

Below are the options I am giving presently

$ ./simph323 -l -n -u listener -i 192.1.4.1 -x 6000 -v V4L2

$ ./simph323 -n -u caller -i 192.1.4.2 -x 5000 -v V4L2 listener@192.1.4.1:6000


My system is X86 , running ubuntu 10.04

Abdul Moiz

Video is enabled via plugins, Build the plugins and place them in the same directory as the application.

You can also use the environmental variable PTLIBPLUGINDIR to point to the directory where the video/audio plugins are.

Hi,

          I am using simph323 application (i.e running two instances one as caller and the other as listener) and able to transfer only "Audio".
Is it possible to transfer "Video" and "Data" also using simph323 application and if so how to give the command line options for the 2 instances (i.e caller and listener)
Or else can anybody suggest me if there is any better application/example to transfer Audio,Video and Data simultaneously.

There are no specific ALSA examples.

However there are a number of same applications contained in the Applications download from the website.

Hi simon,

         Thanks for your response.

    I am a beginner in this field.
I am looking for sample examples/applications which establishes H.323 call and tranfers video,audio and data across 2 systems.
Can you please tell me where can I find the latest sample applications (for Video,Audio and Data) or the related information/document for development of such applications

Oh323tut is getting quite old but here are some tips to get and set the
Audio Driver and Device Name    

Get the drivers
PStringArray names = PSoundChannel::GetDriverNames();

Get the devices
PString DefaultAudioDriver = names[0];
PStringArray playDevices =
PSoundChannel::GetDeviceNames(DefaultAudioDriver,PSoundChannel::Player);
PStringArray recDevices =
PSoundChannel::GetDeviceNames(DefaultAudioDriver,PSoundChannel::Recorder);

Enumerate the devices
for (PINDEX i = 0; i < playDevices.GetSize(); i++) {
       cout << playDevices[i] << endl;
}

To set the driver call these functions
PBoolean H323EndPoint::SetSoundChannelPlayDriver(const PString & name)
PBoolean H323EndPoint::SetSoundChannelRecordDriver(const PString & name)

To set the device call these functions
PBoolean H323EndPoint::SetSoundChannelPlayDevice(const PString & name)
PBoolean H323EndPoint::SetSoundChannelRecordDevice(const PString & name)

Hi,

        I have downloaded the source code of "h323plus core"(version:1.23.0)
and "PTlib"(version:2.10.1) from the link:

http://www.h323plus.org/source/

     on my X86 Desktop system running ubuntu 10.04


   I have followed the tutorial given at link

http://toncar.cz/openh323/tut/index.html

   I am able to compile both the source codes without any problems.

  Then I have downloaded and compiled "oh323tut" (version 1.1-1) source code
from the link below:

http://toncar.cz/openh323/tut/files.html

  I have got simph323 installed on my system using

  $ sudo apt-get install simph323


 Now when I try to run oh323tut application and simph323 application (in
separete terminals) using the commands below:

$ ./oh323tut -f audio.wav -n -u 320
$ simph323 -n -u 321 320@127.0.0.1:1820

   I am getting the following problem:

 H323> Could not open sound device Default - Check permissions or full
duplex capability.


  Can anybody please help to  solve the above problem.
