org.bytedeco.ffmpeg.avutil.AVHWDeviceContext

All Implemented Interfaces:

AutoCloseable

@Properties(inherit=avutil.class)
public class AVHWDeviceContext
extends Pointer

This struct aggregates all the (hardware/vendor-specific) "high-level" state, i.e. state that is not tied to a concrete processing configuration. E.g., in an API that supports hardware-accelerated encoding and decoding, this struct will (if possible) wrap the state that is common to both encoding and decoding and from which specific instances of encoders or decoders can be derived. This struct is reference-counted with the AVBuffer mechanism. The av_hwdevice_ctx_alloc() constructor yields a reference, whose data field points to the actual AVHWDeviceContext. Further objects derived from AVHWDeviceContext (such as AVHWFramesContext, describing a frame pool with specific properties) will hold an internal reference to it. After all the references are released, the AVHWDeviceContext itself will be freed, optionally invoking a user-specified callback for uninitializing the hardware state.

Constructor Detail

AVHWDeviceContext

public AVHWDeviceContext()

Default native constructor.

AVHWDeviceContext

public AVHWDeviceContext(long size)

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

AVHWDeviceContext

public AVHWDeviceContext(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

position

public AVHWDeviceContext position(long position)

Overrides:

position in class Pointer

getPointer

public AVHWDeviceContext getPointer(long i)

Overrides:

getPointer in class Pointer

av_class

@Const
public AVClass av_class()

A class for logging. Set by av_hwdevice_ctx_alloc().

av_class

public AVHWDeviceContext av_class(AVClass setter)

internal

public AVHWDeviceInternal internal()

Private data used internally by libavutil. Must not be accessed in any way by the caller.

internal

public AVHWDeviceContext internal(AVHWDeviceInternal setter)

type

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

This field identifies the underlying API used for hardware access. This field is set when this struct is allocated and never changed afterwards.

type

public AVHWDeviceContext type(int setter)

hwctx

public Pointer hwctx()

The format-specific data, allocated and freed by libavutil along with this context. Should be cast by the user to the format-specific context defined in the corresponding header (hwcontext_*.h) and filled as described in the documentation before calling av_hwdevice_ctx_init(). After calling av_hwdevice_ctx_init() this struct should not be modified by the caller.

hwctx

public AVHWDeviceContext hwctx(Pointer setter)

_free

@Name(value="free")
public AVHWDeviceContext.Free_AVHWDeviceContext _free()

_free

public AVHWDeviceContext _free(AVHWDeviceContext.Free_AVHWDeviceContext setter)

user_opaque

public Pointer user_opaque()

Arbitrary user data, to be used e.g. by the free() callback.

user_opaque

public AVHWDeviceContext user_opaque(Pointer setter)
