Hello! Is it possible to make openam play outgoing message after sending PROGRESS (before CONNECT) and send CONNECT after playing outgoing message to record incoming audio? Thanks.

OpenMCU doesn't mix video
by Adrien Rudulier 22 Jul '08

22 Jul '08

I don't know what happened but openMCU doesn't mix video for me. I was fiddling around getting H.263 at 4CIF to work with PVX and once I got that to work, openMCU no longer mixes video. Everything is fine until the 3rd endpoint connect. The 3rd endpoint then receives the video of a different endpoint and all the video freezes. The video resumes at fullscreen when any endpoint disconnects. I tried removing h323plus, ptlib, and openMCU from my system and reinstalled them with the most recent versions from sourceforge. I was wondering if anybody else is having this problem. __________________________________________________________________ Be smarter than spam.

H.323 Clients
by Adrien Rudulier 16 Jul '08

16 Jul '08

I was wondering if anyone is using an H.323 client with H.263 at 4CIF connecting to openMCU. Also, does MyPhone2 use plugins? Has anybody got MyPhone2 working with H.263? Any response is greatly appreciated. -Adrien __________________________________________________________________ Connect with friends from any web browser - no download required. Try the new Yahoo!

Fw: OpenMCU 4CIF Issues
by Adrien Rudulier 07 Jul '08

07 Jul '08

Simon, I read on a forum that Polycom uses the i263 codec library. It also said that it uses the YUY2( YUV422 ) color space model. I have been trying to convert the decoded YUV422 stream into the YUV420P stream via ptlib but I am having troubles with the YUY2toYUV420PSameSize function in vconvert.cxx crashing during the first execution. Do you have any thoughts on this? ----- Original Message ---- From: Simon Horne <s.horne(a)packetizer.com> To: Adrien Rudulier <rudz04(a)yahoo.ca>; h323plus(a)lists.packetizer.com Sent: Friday, July 4, 2008 6:12:23 PM Subject: RE: [h323plus] OpenMCU 4CIF Issues Adrien BitRate and FrameRate reversed in PacPhone? That a display issue. Well I better fix that. :-) The issue is in the ffmpeg decoder library. From past discussions it a setting issue in the library however the person who found the issue never contributed it back to the project. A contribution to fix the issue from anyone would be very most welcomed.

Do you think the error with PVX and OpenMCU is in the ffmpeg decoder, an un-expected header, or some other reason?

Thank you. Some H.323 endpoint use in-band signalings method such as NetMeeting, while other endpoint such as Polycom PVX use rfc2833 to transfer DTMF. But I don't know how get DTMF info from PVX's audio RTP packets. The code rfc2833.cxx in h323plus seems can not work with PVX. Hello bian the uso of tones, and other in-band signalings depends of the CODEC support, u must read the documentation about the codec u are using if suport in-band signaling. for example G.729 dont suport in-band tones and fax. tip: http://en.wikipedia.org/wiki/G.711 (at botton of page are the others G7xx.x) ___________________________________________________________ 雅虎邮箱，您的终生邮箱！ http://cn.mail.yahoo.com/

hello, Anybody know how rfc2833(DTMF) is used in H.323 system? I have read source code of rfc2833.cxx in h323plus. But it seems that it can not interoperate with PVX. regards. bian ___________________________________________________________ 雅虎邮箱，您的终生邮箱！ http://cn.mail.yahoo.com/
