Infrastructure Plug-ins and Acceleration Software Libraries¶
Infrastructure plug-ins are generic plug-ins that interact with the acceleration kernel through a set of APIs exposed by an acceleration software library corresponding to that kernel. Infrastructure plug-ins abstract the core/common functionality of the GStreamer framework (for example: caps negotiation and buffer management).
Acceleration software libraries control the acceleration kernel, like register programming, or any other core logic required to implement the functions. Acceleration software libraries expose a simplified interface that is called by the GStreamer infrastructure plug-ins to interact with the acceleration kernel.These libraries are used with one of the infrastructure plug-ins to use the functionality a GStreamer-based application. Example pipelines with GStreamer infrastructure plug-ins and acceleration software libraries are covered later in this section.
GStreamer infrastructure plug-ins are available in the vvas-gst-plugins folder in the vvas source code tree. The following section describes each infrastructure plug-in.
