Constructor Details

VideoConverter

public VideoConverter(MemorySegment address)

Create a VideoConverter proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

new_

public static VideoConverter new_(VideoInfo inInfo,
 VideoInfo outInfo,
 Structure config)

Create a new converter object to convert between inInfo and outInfo with config.

Returns (nullable): a GstVideoConverter or null if conversion is not possible.

Parameters:

inInfo - a GstVideoInfo

outInfo - a GstVideoInfo

config - a GstStructure with configuration options

newWithPool

public static VideoConverter newWithPool(VideoInfo inInfo,
 VideoInfo outInfo,
 Structure config,
 @Nullable
 @Nullable TaskPool pool)

Create a new converter object to convert between inInfo and outInfo with config.

The optional pool can be used to spawn threads, this is useful when creating new converters rapidly, for example when updating cropping.

Returns (nullable): a GstVideoConverter or null if conversion is not possible.

Parameters:

inInfo - a GstVideoInfo

outInfo - a GstVideoInfo

config - a GstStructure with configuration options

pool - a GstTaskPool to spawn threads from

frame

public void frame(VideoFrame src,
 VideoFrame dest)

Convert the pixels of src into dest using this VideoConverter.

If GST_VIDEO_CONVERTER_OPT_ASYNC_TASKS is true then this function will return immediately and needs to be followed by a call to gst_video_converter_frame_finish().

Parameters:

src - a GstVideoFrame

dest - a GstVideoFrame

frameFinish

public void frameFinish()

Wait for a previous async conversion performed using gst_video_converter_frame() to complete.

free

public void free()

Free this VideoConverter

getConfig

public Structure getConfig()

Get the current configuration of this VideoConverter.

Returns:

a GstStructure that remains valid for as long as this VideoConverter is valid or until gst_video_converter_set_config() is called.

getInInfo

public VideoInfo getInInfo()

Retrieve the input format of this VideoConverter.

Returns:

a GstVideoInfo

getOutInfo

public VideoInfo getOutInfo()

Retrieve the output format of this VideoConverter.

Returns:

a GstVideoInfo

setConfig

public boolean setConfig(Structure config)

Set config as extra configuration for this VideoConverter.

If the parameters in config can not be set exactly, this function returns false and will try to update as much state as possible. The new state can then be retrieved and refined with gst_video_converter_get_config().

Look at the GST_VIDEO_CONVERTER_OPT_* fields to check valid configuration option and values.

Parameters:

config - a GstStructure

Returns:

true when config could be set.
