pub struct DecoderContextBuilder {
    codec: *const AVCodec,
    context: AvCodecContext,
}

A builder to create a AvCodecContext suitable for decoding.

Fields

codec: *const AVCodec

context: AvCodecContext

Implementations

impl DecoderContextBuilder

pub fn set_get_buffer_2( &mut self, get_buffer2: unsafe extern "C" fn(_: *mut AVCodecContext, _: *mut AVFrame, _: i32) -> i32, opaque: *mut c_void )

Set a custom callback that provides output buffers.

get_buffer2 is a function that decides which buffer is used to render a frame (see libavcodec’s documentation for get_buffer2 for more details). If provided, this function must be thread-safe. opaque is a pointer that will be passed as first argument to get_buffer2 when it is called.

pub fn build(self) -> Result<AvCodecContext, AvCodecOpenError>

Build a decoder AvCodecContext from the configured options.
