Member Function Documentation

virtual MediaBuffer* buffer ( )

pure virtual

Returns the buffer associated with this sample.

Returns: A pointer to a MediaBuffer object. Can be NULL.

virtual double endTime ( ) const

pure virtual

Returns the end time of the media sample.

Returns: The time when the sample should end. Time in seconds.

Remarks: The end time is optional and is valid only if it is greater than the start time.

virtual int32_t flags ( ) const

pure virtual

Returns the media sample flags.

Returns: A combination of flags defined in MediaSampleFlags::Enum.

virtual void setBuffer ( MediaBuffer * buffer )

pure virtual

Sets a new MediaBuffer object.

The old MediaBuffer object is released. The new one is retained.

Parameters

buffer A pointer to the new MediaBuffer object. Can be NULL.

virtual void setEndTime ( double time )

pure virtual

Sets the end time of the media sample.

Parameters

time	[in] The time when the sample should end. Time is in seconds.

Remarks: The end time is optional and is valid only if it is greater than the start time.

virtual void setFlags ( int32_t flags )

pure virtual

Sets the media sample flags.

Parameters

flags [in] A combination of flags defined in MediaSampleFlags::Enum.

virtual void setStartTime ( double time )

pure virtual

Sets presentation timestamp (PTS) of the media sample.

Parameters

time	in seconds

virtual void setStreamNumber ( int32_t streamNumber )

pure virtual

Sets the elementary stream to which the sample belongs.

Parameters

streamNumber [in] A zero-based index of the elementary stream in the container.

virtual double startTime ( ) const

pure virtual

Returns the presentation timestamp (PTS) of the media sample.

Returns: time in seconds

virtual int32_t streamNumber ( ) const

pure virtual

Returns the elementary stream to which the sample belongs.

Returns: A zero-based index of the elementary stream in the container.
