Struct vapoursynth::core::CoreRef

source · [−]

pub struct CoreRef<'core> { /* private fields */ }

Expand description

A reference to a VapourSynth core.

Implementations

source

impl<'core> CoreRef<'core>

source

pub fn info(self) -> Info

Returns information about the VapourSynth core.

source

pub fn get_format(&self, id: FormatID) -> Option<Format<'core>>

Retrieves a registered or preset Format by its id. The id can be of a previously registered format, or one of the PresetFormat.

source

pub fn register_format(
 &self,
 color_family: ColorFamily,
 sample_type: SampleType,
 bits_per_sample: u8,
 sub_sampling_w: u8,
 sub_sampling_h: u8
) -> Option<Format<'core>>

Registers a custom video format.

Returns None if an invalid format is described.

Registering compat formats is not allowed. Only certain privileged built-in filters are allowed to handle compat formats.

RGB formats are not allowed to be subsampled.

source

pub fn get_plugin_by_id(
&self,
id: &str
) -> Result<Option<Plugin<'core>>, NulError>

Returns a plugin with the given identifier.

source

pub fn get_plugin_by_namespace(
&self,
namespace: &str
) -> Result<Option<Plugin<'core>>, NulError>

Returns a plugin with the given namespace.

get_plugin_by_id() should be used instead.

source

pub fn plugins(&self) -> OwnedMap<'core>

Returns a map containing a list of all loaded plugins.

Keys: meaningless unique strings;

Values: namespace, identifier, and full name, separated by semicolons.

source

pub fn set_max_cache_size(&self, bytes: i64) -> i64

Sets the maximum size of the framebuffer cache. Returns the new maximum size.

source

pub fn set_thread_count(&self, threads: i32) -> i32

Sets the number of worker threads for the given core.

If the requested number of threads is zero or lower, the number of hardware threads will be detected and used.

Returns the new thread count.
