Detailed Description

Internal (non type-safe) class used by VideoFileBuffer This does the real interfacing with the ffmpeg library.

Constructor & Destructor Documentation

CVD::VFB::RawVideoFileBuffer::RawVideoFileBuffer	(	const std::string &	file,
		const std::string &	formatname,
		bool	is_rgb,
		bool	verbose,
		const std::map< std::string, std::string > &
	)

Construct a video buffer to play this file.

Public implementation of RawVideoFileBuffer.

Parameters

file	The path to the video file
is_rgb	Is RGB data wanted?

void CVD::VFB::RawVideoFileBuffer::on_end_of_buffer ( VideoBufferFlags::OnEndOfBuffer behaviour )

What should the buffer do when it reaches the end of the list of files?

Parameters

behaviour The desired behaviour

void CVD::VFB::RawVideoFileBuffer::put_frame ( void * f )

Tell the buffer that you are finished with this frame.

Parameters

f	The frame that you are finished with.

void CVD::VFB::RawVideoFileBuffer::seek_to ( double t )

Go to a particular point in the video buffer (only implemented in buffers of recorded video)

Parameters

t	The frame time in seconds
