Module avcodec

This module implements a lightweight and safe decoder interface over libavcodec. It is designed to concentrate all calls to unsafe methods in one place, while providing the same low-level access as the libavcodec functions do.

Structs

AvBuffer

Wrapper around AVBuffer and AVBufferRef.

AvCodec

Lightweight abstraction over libavcodec’s AVCodec struct, allowing the query the capabilities of supported codecs and opening a session to work with them.

AvCodecContext

A codec context from which decoding can be performed.

AvCodecIterator

Lightweight abstraction over libavcodec’s av_codec_iterate function that can be used to enumerate all the supported codecs.

AvError

An error returned by a low-level libavcodec function.

AvFrame

An owned AVFrame, i.e. one decoded frame from libavcodec that can be converted into a destination buffer.

AvFrameBuilder

A builder for AVFrame that allows specifying buffers and image metadata.

AvPacket

An encoded input packet that can be submitted to AvCodecContext::try_send_packet.

AvPixelFormat

Simple wrapper over AVPixelFormat that provides helpful methods.

AvPixelFormatIterator

Lightweight abstraction over the array of supported pixel formats for a given codec.

AvProfile

Simple wrapper over AVProfile that provides helpful methods.

AvProfileIterator

Lightweight abstraction over the array of supported profiles for a given codec.

DecoderContextBuilder

A builder to create a AvCodecContext suitable for decoding.

Dimensions

Dimensions of a frame, used in AvCodecContext and AvFrame.

EncoderContextBuilder

A builder to create a AvCodecContext suitable for encoding.

FromAVPixelFormatError

PlaneDescriptor

A descriptor describing a subslice of buffers in AvFrameBuilder::build_owned that represents a plane’s image data.

Enums

AvCodecOpenError

AvFrameError

TryReceiveResult

Traits

AvBufferSource

Trait for types that can be used as data provider for a AVBuffer.
