int net.sf.ffmpeg_java.AVUtilLibrary.av_fifo_read	(	AVFifoBuffer	f,
		Pointer	buf,
		int	buf_size
	)

Reads data from an AVFifoBuffer.

Parameters:

	*f	AVFifoBuffer to read from
	*buf	data destination
	buf_size	number of bytes to read

int net.sf.ffmpeg_java.AVUtilLibrary.av_fifo_generic_read	(	AVFifoBuffer	f,
		int	buf_size,
		Pointer	func,
		Pointer	dest
	)

Feeds data from an AVFifoBuffer to a user supplied callback.

Parameters:

	buf_size	number of bytes to read
	*func	generic read function
	*dest	data destination

void net.sf.ffmpeg_java.AVUtilLibrary.av_fifo_write	(	AVFifoBuffer	f,
		Pointer	buf,
		int	size
	)

Writes data into an AVFifoBuffer.

Parameters:

	*f	AVFifoBuffer to write to
	*buf	data source
	size	data size

void net.sf.ffmpeg_java.AVUtilLibrary.av_fifo_realloc	(	AVFifoBuffer	f,
		int	size
	)

Resizes an AVFifoBuffer.

Parameters:

	*f	AVFifoBuffer to resize
	size	new AVFifoBuffer size in bytes

void net.sf.ffmpeg_java.AVUtilLibrary.av_fifo_drain	(	AVFifoBuffer	f,
		int	size
	)

Reads and discards the specified amount of data from an AVFifoBuffer.

Parameters:

	*f	AVFifoBuffer to read from
	size	amount of data to read in bytes

long net.sf.ffmpeg_java.AVUtilLibrary.av_rescale	(	long	a,
		long	b,
		long	c
	)

rescale a 64bit integer with rounding to nearest. a simple a*b/c isn't possible as it can overflow

long net.sf.ffmpeg_java.AVUtilLibrary.av_rescale_q	(	long	a,
		AVRational	bq,
		AVRational	cq
	)

rescale a 64bit integer by 2 rational numbers.
