OpenMCU Web page not saving data
by Adrien Rudulier 16 Oct '08

16 Oct '08

OpenMCU's webpage isn't saving the configuration data when I change a value. I did a clean ubuntu install with cvs/svn versions of ptlib, h323plus and openmcu. Does anyone know off the top of their head whether it's a problem with openMCU or should I go talk to the guys at OpalVoip about ptlib? -Adrien __________________________________________________________________ Be smarter than spam.

Noticeable Audio Delay
by Adrien Rudulier 29 Jul '08

29 Jul '08

When I connect to OpenMCU, there is a noticeable audio delay of about 1 second after the video. I was wondering if either OpenMCU or H323plus have a syncronization mechanism. __________________________________________________________________ Instant Messaging, free SMS, sharing photos and more...

SetMaxBitRate Problem
by mohammad alam 25 Jul '08

25 Jul '08

Simon I am using SetMaxBitRate in my code to control data flow in Network. I am using codec.SetMaxBitRate(1024 * x); in OpenVideoChannel(...................... Earlier when I was using Openh323 it was functional. Now I cant control codec BitRate through this API. Do I have to make any changes in Plugins.?? Alam

Re: [h323plus] OpenMCU doesn't mix video

Just to let everybody know, I found the bug in openMCU. When the 4CIF patch was applied, the return value of MCUSimpleVideoMixer::ReadSrcFrame was changed from TRUE to FALSE. -Adrien ----- Original Message ---- From: Adrien Rudulier <rudz04(a)yahoo.ca> To: h323plus(a)lists.packetizer.com Sent: Tuesday, July 22, 2008 3:46:45 PM Subject: [h323plus] OpenMCU doesn't mix video 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. ________________________________ Looking for the perfect gift?Give the gift of Flickr! __________________________________________________________________ Yahoo!

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.

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?
