Detailed Description

This structure is used to share data between the libavcodec library and the client video application.

The user shall zero-allocate the structure and make it available as AVCodecContext.hwaccel_context. Members can be set by the user once during initialization or through each AVCodecContext.get_buffer() function call. In any case, they must be valid prior to calling decoding functions.
