H.263 VIDEO FREEZE when connect 3 endpoints
by Pablo Sotomayor 14 May '10

14 May '10

I just notice another problem with H263 video. When using openmcu with polycom pvx clients, the video is ok when 2 endpoints are connected, when i connect a third pvx software, the video freezes but the audio keep ok. Openmcu and endpoint seems like send receiving data/audio/video. When i connect a fourth pvx endpoint, it shows the frozen video and audio is ok. stats of send/receive data shows traffic too. When i disconnect the second and third endpoint, the video unfreeze and i got video on 4th endpoint. Any help with this H263 issues will be appreciated. Pablo

H.263 + Polycom VSX 7000 + VSX 5000 + PVX
by Pablo Sotomayor 11 May '10

I've been testing the 1.2.2 version of h323plus since last friday and got some H.263 problems. On the testing lab we have a quad-core xeon dell poweredge server running ubuntu 10.04. I installed from ubuntu repositories some system dependencies like ffmpeg, ffmpeg-devel (0.52), libx264, libx264-devel (85), libxvidcore4, libxvidcore-dev, libtheora, etc. From libopalvoip sourceforge files i got ptlib 2.66. From h323plus sourceforge cvs repo, got h323plus and applications. I compiled ptlib, set the PTLIBDIR env variable. Then i compiled h323plus and plugins and set the respective env variables too. Then i compiled openmcu. I run openmcu with loglevel 4 or 5, and i can see all the audio/video codec plugins loading. Focusing on the H263 codec testing, i remove h261 and h264 plugins. Running openmcu only with h263 plugin, i can connect polycom vpx an pacphone endpoints at a openmcu conference room with audio and video support. Audio G711ALaw and H263 CIF video. When i connect the polycom VSX 7000, the openmcu seems like sending/receiving network traffic, but the VSX 7000 show 0K/s on video receve rate on call statistics screen. At the other side, on Polycom PVX software, i can see the video incomming from vsx 7000. Im doing something wrong? There is some polycom configuration that i forgot? Im testing with some Polycom VSX 7000A, VSX 7000A(128) and Polycom VSX 5000 with 8.03, 8.53 and 8.71 firmware versions. Is that a plugin/codec or unexpected header issue? Pablo

H.264 hardware acceleration
by Pablo Sotomayor 10 May '10

It is possible for the openmcu to take advantage of some hardware h264 acceleration devices like these tiny usb dongles (http://www.fastvdo.com/SmartCapture/) or bigger devices like playstation3 runnung linux or the apple iphone/ipad devices? Pablo
