Overview
-The VA API is intended to provide an interface between a video decode/encode/display
+The VA API is intended to provide an interface between a video decode/encode/processing
application (client) and a hardware accelerator (server), to off-load
-video decode/encode/display operations from the host to the hardware accelerator at various
+video decode/encode/processing operations from the host to the hardware accelerator at various
entry-points.
The basic operation steps are:
- Negotiate a mutually acceptable configuration with the server to lock
down profile, entrypoints, and other attributes that will not change on
a frame-by-frame basis.
-- Create a decode context which represents a "virtualized" hardware decode
- device
-- Get and fill decode buffers with picture level, slice level and macroblock
- level data (depending on entrypoints)
-- Pass the decode buffers to the server to decode the current frame
+- Create a video decode, encode or processing context which represents a
+ "virtualized" hardware device
+- Get and fill the render buffers with the corresponding data (depending on
+ profiles and entrypoints)
+- Pass the render buffers to the server to handle the current frame
Initialization & Configuration Management
- Find out supported profiles
- Find out entrypoints for a given profile
- Find out configuration attributes for a given profile/entrypoint pair
-- Create a configuration for use by the decoder
+- Create a configuration for use by the application
