Hello, I don't know if it has been asked before, but I would like to ask anyway.
I have seen a number of online documents, stating that SGX can offload video decoding from the main processor. ( Well, it is not that surprising, considering that all desktop GPUs can do this. )
After googling a little bit I have found this article, which has just what I wanted to see:
http://www.pcreview....s-t2070110.html
The important quote:
"Video is a core competence of handheld graphics processors and is
increasingly a must-have feature, not just in Personal Media Player
products, but also other mobile devices. PowerVR SGX provides outstanding
image quality and frame rates, offloading video codec processing (including
MPEG-4 and H.264) from the main CPU. For video operations the host CPU load
is minimal and the PowerVR SGX part can perform motion estimation, motion
compensation and transform, residual generation, transform, quantisation,
inverse quantisation, inverse transform, image reconstruction, and
deblocking (H.264), making it possible to efficiently off load the tasks
associated with video compression/decompression from the host CPU.
"
.... Well, that's good to see on paper, but where are the actual libraries and programs that can give this ability ? Why I wasn't able to find any post suggesting to use SGX to accelerate video decoding ? Does anyone know of any software that uses SGX to offload video decoding ? ( like plug-in for Gstreamer, video out driver for Mplayer, etc )
I would appreciate to get some info about this
Thanks
