Re: [Gumstix-users] Sending images over wifi

[richard d. <rdo...@gm...>]

Well, first off, how are you sending them? is the socket opened for
UDP? or tcp? TCP requires a considerable amount of overhead on the
line to ensure packet delivery.

Are you asking for each frame? or just sending them non stop?

To get the frame rates up, you want to stream them to the receiver
over UDP, not TCP, for starters. Encapsulate them with something like
mpeg so that you can extract each frame at the receiving end.  That
would help speed things up alot. If your application can tolerate the
occasional dropped packet/corrupted frame, it should work out well for
you.
