H264 Decoder with
OpenMax-IL
We have successfully integrated Sasken’s proprietary
H264 decoder into OpenMAX-IL. This will enable
rapid integration of Sasken codecs onto any
multimedia application that uses OpenMAX-IL.
OpenMAX provides a standard way to write
multimedia codec API which is widely used in the
embedded world. OpenMAX Integration Layer (IL) is a
standard API to access multimedia components on
many platforms.
