mpeg encoding on the GPU ?

Archived from groups: alt.comp.periphs.videocards.nvidia (More info?)

Hi there !

Is it possible to make realtime mpeg-4 encoding

on a nvidia Geforce graphic card,


We wan´t to stream gpu´s framebuffer content in mpeg-4 over a ethernet lan.

Is it possible to get such a gpu with a onboard nic for a better performance
?


with compliments

A dual-core processor in conjunction with some GPU acceleration
should nicely handle the task. Expect to see encoder optimizations for

MPEG-4 and HDV taking advantage of dual-core before having
to crunch the next round of dedicated GPU silicon.
