pub struct CodecContext { /* private fields */ }

AVCodecContext wrapper

Implementations

impl CodecContext

pub fn from_encoder_id(id: AVCodecID) -> Option<CodecContext>

Creates CodecContext from encoder ID

Returns Some(CodecContext) on success, None on error.

pub fn open(&mut self, options: *mut *mut AVDictionary) -> i32

Opens a codec

Returns 0 on success, negative number (Linux error code) on error

TODO

Wrap it into Result<T, A>

pub fn set_size(&mut self, width: i32, height: i32)

Set size of codec picture size

pub fn get_size(&self) -> (i32, i32)

Get size of codec picture size

pub fn set_bitrate(&mut self, bitrate: i64)

Set bitrate

pub fn get_bitrate(&self) -> i64

Get bitrate

pub fn set_framerate(&mut self, fps: i32)

Set framerate (this also sets time_base but in inverse order)

pub fn get_framerate(&self) -> AVRational

Get framerate

pub fn get_time_base(&self) -> AVRational

Get time base

pub fn set_pixel_format(&mut self, fmt: AVPixelFormat)

Set pixel format

pub fn get_pixel_format(&self) -> AVPixelFormat

Get pixel format

pub fn set_gop_size(&mut self, gop_size: i32)

pub fn get_gop_size(&self) -> i32

pub fn set_max_b_frames(&mut self, max_b_frames: i32)

pub fn fill_parameters(&self, params: *mut AVCodecParameters)

Fills parameters from codec into params

pub fn set_flags(&mut self, flags: i32)

Set codec flags

pub fn get_flags(&self) -> i32

Get codec flags

pub fn send_frame(&mut self, frame: &mut Frame) -> i32

Send frame to codec

pub unsafe fn receive_packet(&mut self, out: *mut AVPacket) -> i32

Receive packet from codec to out

pub fn is_open(&self) -> bool

Returns true if codec is opened.
