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.).

Method Detail

position

public avutil.AVClass position(int position)

Overrides:

position in class Pointer

class_name

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

public avutil.AVClass.Item_name_Pointer item_name()

option

public avutil.AVOption option()

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

See Also:

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

public avutil.AVClass.Child_class_next_AVClass child_class_next()

category

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

get_category

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