Re: [h323plus] Need help to run oh323tut application using ALSA

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

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****
