[Freeswitch-users] Video pass problem

[Mikhail Krivushin]

We use two different OSes - stable debian and bleeding edge ubuntu, but
problem live in both.
I think problem not in bleeding edge OS, but in way of processing rtp by FS.
I'm not sure, but think problem in renumerating of rtp packets in video
processing in mod_h26x.

If we have video problems with lost packets, after FS we have not this info,
its mascarade losts by renumerating. And, I suppose, decoding part cant
understand video with masacarding of lost frames.

All work fine with proxy mode, now, after small patching of old hack in
switch_rtp.c, tnx to anthm. But my billing module dont work in proxy mode
now, and I hear that proxy mode is hack for t.38.
