Class avutil.AVClass

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.javacpp.avutil.AVClass

Enclosing class:

avutil

public static class avutil.AVClass
extends Pointer

Describe the class of an AVClass context structure. That is an arbitrary struct of which the first field is a pointer to an AVClass struct (e.g. AVCodecContext, AVFormatContext etc.).

Constructor Detail

AVClass

public AVClass()

Default native constructor.

AVClass

public AVClass(int size)

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

AVClass

public AVClass(Pointer p)

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

Method Detail

position

public avutil.AVClass position(int position)

Overrides:

position in class Pointer

class_name

@MemberGetter
 @Cast(value="const char*")
public BytePointer class_name()

The name of the class; usually it is the same name as the context structure type to which the AVClass is associated.

item_name

@MemberGetter
public avutil.AVClass.Item_name_Pointer item_name()

option

@MemberGetter
 @Const
public avutil.AVOption option()

a pointer to the first option specified in the class if any or NULL

av_set_default_options()

version

public int version()

LIBAVUTIL_VERSION with which this structure was created. This is used to allow fields to be added without requiring major version bumps everywhere.

version

public avutil.AVClass version(int version)

log_level_offset_offset

public int log_level_offset_offset()

Offset in the structure where log_level_offset is stored. 0 means there is no such variable

log_level_offset_offset

public avutil.AVClass log_level_offset_offset(int log_level_offset_offset)

parent_log_context_offset

public int parent_log_context_offset()

Offset in the structure where a pointer to the parent context for logging is stored. For example a decoder could pass its AVCodecContext to eval as such a parent context, which an av_log() implementation could then leverage to display the parent context. The offset can be NULL.

parent_log_context_offset

public avutil.AVClass parent_log_context_offset(int parent_log_context_offset)

child_next

public avutil.AVClass.Child_next_Pointer_Pointer child_next()

child_next

public avutil.AVClass child_next(avutil.AVClass.Child_next_Pointer_Pointer child_next)

child_class_next

@MemberGetter
public avutil.AVClass.Child_class_next_AVClass child_class_next()

category

@Cast(value="AVClassCategory")
public int category()

Category used for visualization (like color) This is only set if the category is equal for all objects using this class. available since version (51 << 16 | 56 << 8 | 100)

category

public avutil.AVClass category(int category)

get_category

public avutil.AVClass.Get_category_Pointer get_category()

get_category

public avutil.AVClass get_category(avutil.AVClass.Get_category_Pointer get_category)
