Class avfilter.AVFilterBuffer

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.javacpp.avfilter.AVFilterBuffer

Enclosing class:

avfilter

public static class avfilter.AVFilterBuffer
extends Pointer

A reference-counted buffer data type used by the filter system. Filters should not store pointers to this structure directly, but instead use the AVFilterBufferRef structure below.

Constructor Detail

AVFilterBuffer

public AVFilterBuffer()

Default native constructor.

AVFilterBuffer

public AVFilterBuffer(int size)

Native array allocator. Access with Pointer.position(int).

AVFilterBuffer

public AVFilterBuffer(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

position

public avfilter.AVFilterBuffer position(int position)

Overrides:

position in class Pointer

data

@Cast(value="uint8_t*")
public BytePointer data(int i)

buffer data for each plane/channel

data

public avfilter.AVFilterBuffer data(int i,
                                    BytePointer data)

data

@MemberGetter
 @Cast(value="uint8_t**")
public PointerPointer data()

extended_data

@Cast(value="uint8_t*")
public BytePointer extended_data(int i)

pointers to the data planes/channels. For video, this should simply point to data[]. For planar audio, each channel has a separate data pointer, and linesize[0] contains the size of each channel buffer. For packed audio, there is just one data pointer, and linesize[0] contains the total size of the buffer for all channels. Note: Both data and extended_data will always be set, but for planar audio with more channels that can fit in data, extended_data must be used in order to access all channels.

extended_data

public avfilter.AVFilterBuffer extended_data(int i,
                                             BytePointer extended_data)

extended_data

@MemberGetter
 @Cast(value="uint8_t**")
public PointerPointer extended_data()

linesize

public int linesize(int i)

number of bytes per line

linesize

public avfilter.AVFilterBuffer linesize(int i,
                                        int linesize)

linesize
