[Asterisk-video] mpeg4 video and h.263

[Joe Baltes]

Eaxctly. Some of the older products like OnLan especially will never support H.264... OnLan is really 'Lost to the Sands of Time' anyway. The version ~3+ of ViaIP GWs and all current Scopia series GWs will support H.264 by default. 

Hope that helps.

	Hi,
	
	RADVISION products all support H.264.
	

Even the older ones (ViaIP 400 - part no 55580-00001)?

I did capture a trace of an h.323 call setup and only saw H.263 & MPEG4 being offered.... but then that's probably because the phone I was testing with only supported those 2 codecs.

Might try with a newer phone that supports h.264 and see what I get.

	        We have done some work on ooh323 and H.264. We can add MPE4G support if

	        Still I do not understand the need: ig you go through a RADVISION 3G
	        gateway  you will need only H.263 support that. No?
	         
	
	Yes that's right, but there is a reasonably significant improvement in video quality of you go MPEG-4
	Of course h.264 (MPEG4 Level 10) would be the best, but Radvision (AFAIK) do not support that.
	
	
	        I know that H.324m makes the provision of using MPEG4 video as codec but
	        I have not seen a single terminal that support it.
	         
	
	Nokia 6110, Motorola Razor V-series,  Nokia 6220 etc all support MPEG4.
	In fact most of the newer (<3 years) video mobile phones do.

	                Hi,
	               
	                I have built asterisk with video support and ooh323.
	               
	                Using a Radvision gateway, I can place a 3g call and play video using
	                h.323 signaling with the h.263 video codec.
	               
	                ooh323 does not support the mpeg4 codec when it negotiates terminal
	                endpoint capabilities.
	               
	                Does anyone know of a way to support the mpeg4 codec with asterisk using
	                h.323 signaling?
	               
	                Thanks,
