PTimedMutex::Wait patch
by Nir Soffer 17 Feb '09

17 Feb '09

In PTimedMutex::Wait(const PTimeInterval & waitTime), when pthread_mutex_timedlock is not available or broken (it is broken on our arm platform), the code always sleeps before checking the finish time, which is incorrect. For example, if you call Wait(0), and fail to acquire the lock, you will sleep for 10 milliseconds before you get back the retrun value. This is a bigger issue if you use H323EndPoint::FindConnectionWithLock: PWaitAndSignal mutex(connectionsMutex); H323Connection * connection; while ((connection = FindConnectionWithoutLocks(token)) != NULL) { // XXX this will block for 10 milliseconds if the lock can not be acquired! // TryLock calls Wait(0) which sleeps for 10ms on failure switch (connection->TryLock()) { case 0 : return NULL; case 1 : return connection; } // Could not get connection lock, unlock the endpoint lists so a thread // that has the connection lock gets a chance at the endpoint lists. connectionsMutex.Signal(); PThread::Sleep(20); connectionsMutex.Wait(); } return NULL; The code try sleep for 20 milliseconds while the connectionsMutex is unlocked, letting the other thread that hold the connection a chancee to use the endpoint lists, but for each 30 milliseconds cycle, it keeps the endpoint lists locked for 10 milliseconds. Attached a trivial fix. Best Regards, Nir Soffer

hi you can close audio channel as a mute function. and restart channel on unmute through connection object.

mute/unmute
by Marcus Frenkel 12 Feb '09

12 Feb '09

Hi, First, I would like to thank Packetizer for continuing the open h323 development. Ptlib/h323plus have big set of functions, but I'm not able to find the right one I need. Is there any function to mute/unmute the input sound device while the call is in progress? Any help is greatly appreciated. Marcus

New in this release are executables for NetBSD and Solaris x86. To compile GnuGk 2.2.7 you can use OpenH323 Atlas (OpenH323 1.18.0 / PWLib 1.10.3) or the latest H323Plus release. For high volume installations Atlas is the preferred library. Please see http://www.gnugk.org/compiling-gnugk.html for details on compiling.

swap audio record & player device
by Eleoson Gonzales 01 Dec '08

01 Dec '08

Hello, I would like to use a bluetooth controlled mobile. basically if you connect the mobile to your pc the pc's speaker & mic will become the mobile's speaker & mic. Therefore, I will need to swap the recorder & player device so that h323plus will encode the speaker's audio (player device) and send it to remote endpoint, and decode the microphone's audio (record device) and send it to the local mobile phone. thanks in advance! regards, Eleoson

The CVS code is neutral, compiles in any POSIX compliant system. You will need to inform to the 'configure' program the default system output folder and set proper enviroment variables, some systems need a little more tricks on the config.in file, but not the case of Debian.
