[asterisk-users] Video codecs: H263 & H264

[Alex Saavedra]

Jonas,

I've been using H.264 and H.263+ with a few Grandstream GVX3140. When using
H.264 the image quality was better, and required bandwidth appeared lower
compared with H.263+. In fact H.264 is expected to consume less bandwidth
for as much as 50% (according to Wikipedia). Note however that when
configuring bandwidth limits inside Asterisk (maxcallbitrate directive) I
saw no effect on client devices. Only client configuration succeeded (v
1.6.2.7 here).

I kept H.263+ only for compatibility reasons when using X-Lite softphone (no
support for H.264).

Regards,

Alex Saavedra
