Struct rsmpeg::avfilter::AVFilterGraph

pub struct AVFilterGraph { /* fields omitted */ }

Implementations

impl AVFilterGraph

pub fn as_ptr(&self) -> *const AVFilterGraph

pub fn as_mut_ptr(&mut self) -> *mut AVFilterGraph

pub unsafe fn set_ptr(&mut self, ptr: NonNull<AVFilterGraph>)

Safety

This function should only be called when the pointer is valid and the data it’s pointing to can be dropped.

pub unsafe fn from_raw(raw: NonNull<AVFilterGraph>) -> Self

Safety

This function should only be called when the pointer is valid and the data it’s pointing to can be dropped.

pub fn into_raw(self) -> NonNull<AVFilterGraph>

impl AVFilterGraph

pub fn new() -> Self

Allocate a filter graph.

pub fn parse_ptr(
    &self,
    filter_spec: &CStr,
    inputs: AVFilterInOut,
    outputs: AVFilterInOut
) -> Result<(Option<AVFilterInOut>, Option<AVFilterInOut>)>

Add a graph described by a string to a AVFilterGraph.

This function returns the inputs and outputs (if any) that are left unlinked after parsing the graph and the caller then deals with them.

pub fn config(&self) -> Result<()>

Check validity and configure all the links and formats in the graph.

impl<'graph> AVFilterGraph

pub fn create_filter_context(
    &'graph self,
    filter: &AVFilter,
    name: &CStr,
    args: Option<&CStr>
) -> Result<AVFilterContextMut<'graph>>

Create and add a AVFilter instance into an existing AVFilterGraph. The filter instance is created from the filter and inited with the parameter args.

impl Deref for AVFilterGraph

type Target = AVFilterGraph

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target
