how to support directshow
by JobsGuo(Guo Huayong) 10 Dec '08

10 Dec '08

Hi,all. when I compile the ptlib-v2_0_1,I find the config in ptbuildopts.h show below: ///////////////////////////////////////////////// // // DirectX Support (Windows only) // #ifndef _WIN32_WCE #define P_DIRECTSOUND 1 #undef P_DIRECTSHOW #undef P_VFW_CAPTURE #endif So I can not get the directshow support.but I can get the directsound support.I indeed install directx 9.0c.so it can find the directx file. but why it can not find the directshow? Besides,I also can not find the dshow.h. Who can help me ?thanks! 2008-11-28 JobsGuo(Guo Huayong) Mobile：13918103120 QQ ： 360480589 MSN ： ghyhust(a)hotmail.com

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

t38modem and freebsd tty error

Hello... I am trying to run t38modem on a freebsd 6.x server (also running hylafax). Apparently the t38modem binary cannot attach to the tty device. PseudoModemPty::OpenPty tcgetattr ptypa ERROR: Resource temporarily unavailable I have tried many different combinations of tty choices and args, but all fail in the same way. Am I missing something?

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.

IE element decode
by robertp 04 Nov '08

04 Nov '08

lo, i've been harnessing the Q931 class of h323plus to decode packets off the wire, however i'm a little confused as to how h323plus decodes the contents of the information elements which are contained within Q931. i assumed (apparently wrongly) that you would do a check for an element by using Q931.HasIE(), get the byte array of the IE using Q931.GetIE(), then call something like Q931.decodeUserUserIE which returns a structure of some sort which can have methods such as getConferenceGuid() called upon it. I've done the first few steps upto GetIE(), and i now have a PBYTEARRAY of the IE, but i've no idea what to do with it now to decode its contents in a workable, consistent manner. I've poured through the h323+ code, but i cant seem to find where the code deals with this problem. perhaps h323pdu plays a role ?? -- To clarify, i'm sniffing packets off the wire, i.e: mid call, so i'm not an endpoint in the call, rather a onlooker. I don't have transport objects or anything such, i just want to decode the packets and view their contents. - Thanks in advance.

bug in rtp.cxx
by robertp 28 Oct '08

28 Oct '08

line 883 of rtp.cxx is bugged, you're deleting jitter, even if the audio disable has been used for the build. This causes a build error. Also, how reliant is h323plus on the forked sections of ptlib ? Its rather annoying having to build against a customised version. Would it be at all reasonable to make a motion towards merging the ptlib found in other sources such as the ubuntu repositories, and the ptlib given on the h323plus website ? Thanks in advance. - R

Re: [h323plus] How to split audio

RE: [h323plus] How to split audioHi, dansukcu! The best way is deriving H323Codec class and override "write" function (followings for example) and then use it in OpenAudioChannel function. BOOL H323_XXX_Audio_Codec::Write(const BYTE * buffer, unsigned length, const RTP_DataFrame & /*rtpFrame*/, unsigned & written) { ... } BOOL H323_XXX_Audio_Codec::WriteRaw(void * data, PINDEX length) { ... } ... If you want to do more process of the splited audio data, you may also need to implement your own SoundChannel.
