The problem is the generic information on profile and level are not being read from the plugin and exchanged. The same problem exists with MPEG4 plugins.

Currently working on a fix.

Hello Chin

H264 (and other resolutions above 4CIF and like vga, wvga etc) is not part of H323 stack. One way to use it is with the extended video capability, them both end-points can agree on a specific and possible proprietary CODECs.

2009/11/17 ooi khai chin ooikhaichin@yahoo.com:

Hi All, currently, I had been compiled the h264plugin from opal project, together with libx264,avcodec and any stuff to make it work.

when, I do a conference on both side using my own codec in MyPhone2, It work fined.

The problem occur when I communicate with other voip software like polycom, VCON...

In the polycom(PVX 8.0.2) media statistic, it show both side info as

below:

People Tx     People Rx

Video Protocol:                H.264           H.264 Video

Rate:

320              320 Video Rate Used:             319              84 Video Frame Rate:           15                0 Video Packet

Lost:

0                 0 Video jitter:                      0                 2 Video Format:              QVGA         -----

Audio Protocol:            G.711U       G.711A Audio

Rate:

64                  64 Audio Packets Lost:      0                    0 Audio Jitter:                   0                   0

The frame rate and video format got problem...

Do I need to specify video format and video frame rate in H323plus (generic capability), Any Idea???

Thanks.
