Struct VideoInfoDmaDrm

Source

pub struct VideoInfoDmaDrm(/* private fields */);

Expand description

Information describing a DMABuf image properties. It wraps VideoInfo and adds DRM information such as drm-fourcc and drm-modifier, required for negotiation and mapping.

Implementations§

Source §

impl VideoInfoDmaDrm

Source

pub fn new(info: VideoInfo, fourcc: u32, modifier: u64) -> VideoInfoDmaDrm

Allocate a new VideoInfoDmaDrm that is also initialized with [init()][Self::init()].

§Returns

a new VideoInfoDmaDrm. Free it with gst_video_info_dma_drm_free().

Source

pub fn is_valid(&self) -> bool

Source

pub fn from_caps(caps: &CapsRef) -> Result<Self, BoolError>

Parse caps to generate a VideoInfoDmaDrm. 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.

§`caps`

a gst::Caps

§Returns

A VideoInfoDmaDrm, or None if caps couldn’t be parsed.

Source

pub fn to_caps(&self) -> Result<Caps, BoolError>

Convert the values of self into a gst::Caps. 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 gst::Caps containing the info in self.

Source

pub fn from_video_info( video_info: &VideoInfo, modifier: u64, ) -> Result<Self, BoolError>

Fills drm_info if info’s format has a valid drm format and modifier is also valid

§`info`

a VideoInfo

§`modifier`

the associated modifier value.

§Returns

true if drm_info is filled correctly.

§`drm_info`

VideoInfoDmaDrm

Source

pub fn to_video_info(&self) -> Result<VideoInfo, BoolError>

Convert the VideoInfoDmaDrm into a traditional VideoInfo with recognized video format. For DMA kind memory, the non linear DMA format should be recognized as VideoFormat::DmaDrm. This helper function sets info’s video format into the default value according to self’s drm_fourcc field.

§Returns

true if info is converted correctly.

§`info`

VideoInfo

Source

pub fn fourcc(&self) -> u32

Source

pub fn modifier(&self) -> u64

Methods from Deref<Target = VideoInfo>§

Source

pub fn is_valid(&self) -> bool

Source

pub fn to_caps(&self) -> Result<Caps, BoolError>

Convert the values of self into a gst::Caps.

§Returns

a new gst::Caps containing the info of self.

Source

pub fn convert<U: SpecificFormattedValueFullRange>( &self, src_val: impl FormattedValue, ) -> Option

Converts among various gst::Format types. This function handles GST_FORMAT_BYTES, GST_FORMAT_TIME, and GST_FORMAT_DEFAULT. For raw video, GST_FORMAT_DEFAULT corresponds to video frames. This function can be used to handle pad queries of the type GST_QUERY_CONVERT.

§`src_format`

gst::Format of the src_value

§`src_value`

value to convert

§`dest_format`

gst::Format of the dest_value

§Returns

TRUE if the conversion was successful.

§`dest_value`

pointer to destination value

Source

pub fn convert_generic( &self, src_val: impl FormattedValue, dest_fmt: Format, ) -> Option<GenericFormattedValue>

Source

pub fn range_offsets(&self, range: VideoColorRange) -> ([i32; 4], [i32; 4])
