[x264-devel] x264-devel Digest, Vol 58, Issue 16

Wed Mar 21 14:18:41 CET 2012

edward,

i forget to post my cuda research, maybe that can help you.

1) commerical but not expensive cuda encoder (including SDK):
http://www.mainconcept.com/?id=419
(Sorenson for example uses this cuda SDK)

2) nvidia own cuda h.264 encoder, comes with cuda toolkit:
http://developer.download.nvidia.com/compute/DevZone/docs/html/C/doc/CUDA_VideoEncoder_Library.pdf
(I only saw windows.dll version of this encoder, no lnx or osx)

3) http://www.badaboomit.com
Cheap Cuda encoder windows app

But..as i said before i loosed a lot of my life time for testing all the 
cuda stuff out. At the end of the day i came back to x264 or for some of 
my customers to ateme encoders.
