Using OpenMAX Integration Layer with GStreamer

5 CONCLUSIONS
In this white paper we have discussed how the OpenMAX Integration Layer API
specified by the Khronos group can be used in the Linux GStreamer multimedia
framework.
The interaction among GST elements and OpenMAX base profile components has
been shown for a simple MP3 decoding example.
By just providing GST plugins with elements that use the Integration Layer API, it is
possible to exploit standardized access to multimedia components in a platform
independent way.
If hardware acceleration is available, OpenMAX IL provides a convenient mechanism
to exploit it, including data path optimization features that concur in reducing power
consumption and offloading the host CPU.
