Hi all,
I am having a doubt regarding the
hardware and codecs in OpenH323.
Supposing I am having one VoIP card
(say Quicknet or equivalent), now it supports G.711, 723.1,728,729, but it does
not support G.722/726 codec.
And I want my application to have support for
all the above mentioned codecs.
So the path for the coding/deconding will be
different for both of the above mentioned sets. Because first codec set is h/w
based in which the stream has to pass through the h/w and the second set is the
s/w codec which may be taking the streams from the standard sound card.
So is this senario possible in the same setup. And
moreover, If I am having the VoIP card then Do I need a separate sound
card.
In simpler terms, I mean to say is that that
todays' PCs come with the internal speaker and onboard sound cards. So when I
install a VoIP card, then for sending the Audio suppose I connect the microphone
with VoIP point, then what will be the fate of G.722/G.726 streams becasue in
that case sound card will not come into the picture. And is it so that we can't
have that codec support. Also while listening the incoming voice, I can listen
on the headset connected to VoIP card, but what if I want to listen on the PC
speaker then will it be possible becasue that has the connection with the sound
card in the system.
Same is the query with the H.263 supported Video
card. Because I think my Web Cam need to be plugged into the Video streaming
card.
Thanks and Regards,
Ashutosh.
