Detailed Description

The parameter represents a MediaBuffer object.

Member Function Documentation

buffer()

virtual primo::codecs::MediaBuffer * buffer ( ) const

pure virtual

Returns the buffer instance.

Returns

A pointer to MediaBuffer object. The returned pointer can be NULL.

setBuffer()

virtual bool_t setBuffer ( primo::codecs::MediaBuffer *  buffer )

pure virtual

Sets the buffer.

Parameters

buffer

[in] A pointer to MediaBuffer that will be stored in the parameter. It is allowed to set a NULL object. Internally the MediaBuffer specified by buffer is retained (if not NULL), so it is safe to release it after this method returns. The previous MediaBuffer is released (if not NULL).
