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.

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.
