Struct rsmpeg::avcodec::AVCodecContext

pub struct AVCodecContext { /* fields omitted */ }

Implementations

impl AVCodecContext

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

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

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

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<AVCodecContext>) -> Self

Safety

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

impl AVCodecContext

pub fn new(codec: &AVCodec) -> Self

Create a new AVCodecContext instance, allocate private data and initialize defaults for the given AVCodec.

pub fn open(
    &mut self,
    dict: Option<AVDictionary>
) -> Result<Option<AVDictionary>>

Initialize the AVCodecContext.

dict: A AVDictionary filled with AVCodecContext and AVCodec private options. Function returns a AVDictionary filled with options that were not found if given dictionary. It can usually be ignored.
