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.
Regards, Abdul Moiz

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.
Regards
