Hi Ketan, I fully agree that there’s an exterme lack of documentation and support for a lot of media playback, especially in the OpenMAX world. Retrieved from ” https: The building blocks might be used to accelerate traditional computational hotspots within standardized media codecs and other integrated media processing engines.
Implementing custom codecs Stagefright comes with built-in software codecs for common media formats, but you can also add your own custom hardware codecs as OpenMAX components.
This flexible core architecture allows the Integration Layer to easily implement almost any media use oprnmax and mesh with existing graph-based media frameworks. Here are the answers to your questions. You must provide an OpenMAX plugin in the form of a shared library named libstagefrighthw.
