Discussion on FarSight

[Taupter]

Hello there.


After a long time offline (I was moving from Fortaleza to Brazilia, 1700km far 
from each other), I'm back. As I got online today, maybe I'm a bit outdated 
about the current trend, so I'll waste one day trying to catch up.
AFAIK Gstreamer is a really good framework, but maybe it's still a moving 
target, that could add an uneeded dependency to kopete. As it's C/glib, some 
people may become upset, and I feel a bit afraid about how to glue things 

About avdevice, my real plan about it is to make it part of the KDE framework, 
but trying to simplify it as much as I can in terms of API (to the point 
one's application could just getFrame() and the device would be automaticly 
opened, default parameters get set and some other niceties, as concurrent 
access. It will be a lot of effort (and I think it's worth) but it may take 
time to do it just right.
About encoding/compressing, it's not really a hardware stuff at all (despite 
V4L2's support to MJPEG cards) and maybe we could simply feed any given codec 
with an image (not neccessarily a QPixmap, as it currently doesn't support 
YUV420P and friends).
3 layers: Audio/video capture; codec handling; displaying. I think we should 
select what fits better to Kopete/KDE in each aspect, and do the thing right. 
I'm pretty sure we'll have a good support for it before KDE 3.5 sees the 
light of day.


Best regards,


Cláudio Pinheiro
