Constructor Details

VideoInfoDmaDrm

public VideoInfoDmaDrm(MemorySegment address)

Create a VideoInfoDmaDrm proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

VideoInfoDmaDrm

public VideoInfoDmaDrm()

Allocate a new GstVideoInfoDmaDrm that is also initialized with gst_video_info_dma_drm_init().

Since:

1.24

Method Details

getType

public static @Nullable Type getType()

Get the GType of the VideoInfoDmaDrm class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

readVinfo

public @Nullable VideoInfo readVinfo()

Read the value of the field vinfo.

Returns:

The value of the field vinfo

writeVinfo

public void writeVinfo(@Nullable VideoInfo vinfo)

Write a value in the field vinfo.

Parameters:

vinfo - The new value for the field vinfo

readDrmFourcc

public int readDrmFourcc()

Read the value of the field drm_fourcc.

Returns:

The value of the field drm_fourcc

writeDrmFourcc

public void writeDrmFourcc(int drmFourcc)

Write a value in the field drm_fourcc.

Parameters:

drmFourcc - The new value for the field drm_fourcc

readDrmModifier

public long readDrmModifier()

Read the value of the field drm_modifier.

Returns:

The value of the field drm_modifier

writeDrmModifier

public void writeDrmModifier(long drmModifier)

Write a value in the field drm_modifier.

Parameters:

drmModifier - The new value for the field drm_modifier

fromCaps

public static VideoInfoDmaDrm fromCaps(Caps caps)

Parse caps to generate a GstVideoInfoDmaDrm. Please note that the caps should be a dma drm caps. The gst_video_is_dma_drm_caps() can be used to verify it before calling this function.

Parameters:

caps - a GstCaps

Returns:

A GstVideoInfoDmaDrm, or null if caps couldn't be parsed.

Since:

1.24

withCaps

public static boolean withCaps(VideoInfoDmaDrm drmInfo,
 Caps caps)

Parse caps and update info. Please note that the caps should be a dma drm caps. The gst_video_is_dma_drm_caps() can be used to verify it before calling this function.

Parameters:

drmInfo - GstVideoInfoDmaDrm

caps - a GstCaps

Returns:

TRUE if caps could be parsed

Since:

1.24

fromVideoInfo

public static boolean fromVideoInfo(VideoInfoDmaDrm drmInfo,
 VideoInfo info,
 long modifier)

Fills drmInfo if info's format has a valid drm format and modifier is also valid

Parameters:

drmInfo - GstVideoInfoDmaDrm

info - a GstVideoInfo

modifier - the associated modifier value.

Returns:

true if drmInfo is filled correctly.

Since:

1.24

init

public static void init(VideoInfoDmaDrm drmInfo)

Initialize drmInfo with default values.

Parameters:

drmInfo - a GstVideoInfoDmaDrm

Since:

1.24

free

public void free()

Free a GstVideoInfoDmaDrm structure previously allocated with gst_video_info_dma_drm_new()

Since:

1.24

toCaps

public @Nullable Caps toCaps()

Convert the values of this VideoInfoDmaDrm into a GstCaps. Please note that the caps returned will be a dma drm caps which sets format field to DMA_DRM, and contains a new drm-format field. The value of drm-format field is composed of a drm fourcc and a modifier, such as NV12:0x0100000000000002.

Returns:

a new GstCaps containing the info in drmInfo.

Since:

1.24

toVideoInfo

public boolean toVideoInfo(VideoInfo info)

Convert the GstVideoInfoDmaDrm into a traditional GstVideoInfo with recognized video format. For DMA kind memory, the non linear DMA format should be recognized as GST_VIDEO_FORMAT_DMA_DRM. This helper function sets info's video format into the default value according to drmInfo's drm_fourcc field.

Parameters:

info - GstVideoInfo

Returns:

true if info is converted correctly.

Since:

1.24
