Constructor Details

VideoChromaResample

public VideoChromaResample(MemorySegment address)

Create a VideoChromaResample proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

new_

public static VideoChromaResample new_(VideoChromaMethod method,
 Set<VideoChromaSite> site,
 Set<VideoChromaFlags> flags,
 VideoFormat format,
 int hFactor,
 int vFactor)

Create a new resampler object for the given parameters. When hFactor or vFactor is > 0, upsampling will be used, otherwise subsampling is performed.

Parameters:

method - a GstVideoChromaMethod

site - a GstVideoChromaSite

flags - GstVideoChromaFlags

format - the GstVideoFormat

hFactor - horizontal resampling factor

vFactor - vertical resampling factor

Returns:

a new GstVideoChromaResample that should be freed with gst_video_chroma_resample_free() after usage.

new_

public static VideoChromaResample new_(VideoChromaMethod method,
 VideoChromaSite site,
 VideoChromaFlags flags,
 VideoFormat format,
 int hFactor,
 int vFactor)

Create a new resampler object for the given parameters. When hFactor or vFactor is > 0, upsampling will be used, otherwise subsampling is performed.

Parameters:

method - a GstVideoChromaMethod

site - a GstVideoChromaSite

flags - GstVideoChromaFlags

format - the GstVideoFormat

hFactor - horizontal resampling factor

vFactor - vertical resampling factor

Returns:

a new GstVideoChromaResample that should be freed with gst_video_chroma_resample_free() after usage.

videoChromaResample

public void videoChromaResample(@Nullable MemorySegment lines,
 int width)

Perform resampling of width chroma pixels in lines.

Parameters:

lines - pixel lines

width - the number of pixels on one line

free

public void free()

Free this VideoChromaResample

getInfo

public void getInfo(@Nullable Out<Integer> nLines,
 @Nullable Out<Integer> offset)

The resampler must be fed nLines at a time. The first line should be at offset.

Parameters:

nLines - the number of input lines

offset - the first line
