Class avfilter.AVFilterBufferRef

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.javacpp.avfilter.AVFilterBufferRef

Enclosing class:

avfilter

public static class avfilter.AVFilterBufferRef
extends Pointer

A reference to an AVFilterBuffer. Since filters can manipulate the origin of a buffer to, for example, crop image without any memcpy, the buffer origin and dimensions are per-reference properties. Linesize is also useful for image flipping, frame to field filters, etc, and so is also per-reference. TODO: add anything necessary for frame reordering

Constructor Detail

AVFilterBufferRef

public AVFilterBufferRef()

Default native constructor.

AVFilterBufferRef

public AVFilterBufferRef(int size)

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

AVFilterBufferRef

public AVFilterBufferRef(Pointer p)

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

Method Detail

position

public avfilter.AVFilterBufferRef position(int position)

Overrides:

position in class Pointer

buf

public avfilter.AVFilterBuffer buf()

the buffer that this is a reference to

buf

public avfilter.AVFilterBufferRef buf(avfilter.AVFilterBuffer buf)

data

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

picture/audio data for each plane

data

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

linesize

@MemberGetter
public IntPointer linesize()

video

public avfilter.AVFilterBufferRefVideoProps video()

video buffer specific properties

video

public avfilter.AVFilterBufferRef video(avfilter.AVFilterBufferRefVideoProps video)

audio

public avfilter.AVFilterBufferRefAudioProps audio()

audio buffer specific properties

audio

public avfilter.AVFilterBufferRef audio(avfilter.AVFilterBufferRefAudioProps audio)

pts

public long pts()

presentation timestamp. The time unit may change during filtering, as it is specified in the link and the filter code may need to rescale the PTS accordingly.

pts

public avfilter.AVFilterBufferRef pts(long pts)

pos

public long pos()

byte position in stream, -1 if unknown

pos

public avfilter.AVFilterBufferRef pos(long pos)

format

public int format()

media format

format

public avfilter.AVFilterBufferRef format(int format)

perms

public int perms()

permissions, see the AV_PERM_* flags

perms

public avfilter.AVFilterBufferRef perms(int perms)

type

@Cast(value="AVMediaType")
public int type()

media type of buffer data

type

public avfilter.AVFilterBufferRef type(int type)

metadata

public avutil.AVDictionary metadata()

dictionary containing metadata key=value tags

metadata

public avfilter.AVFilterBufferRef metadata(avutil.AVDictionary metadata)
