Struct ffmpeg::avcodec::AvCodec

pub struct AvCodec(&'static AVCodec);

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

AVCodec instances in libavcodec are all static, hence we can safely use a static reference lifetime here.

Implementations

impl AvCodec

pub fn is_decoder(&self) -> bool

Returns whether the codec is a decoder.

pub fn is_encoder(&self) -> bool

Returns whether the codec is an encoder.

pub fn name(&self) -> &'static str

Returns the name of the codec.

pub fn capabilities(&self) -> u32

Returns the capabilities of the codec, as a mask of AV_CODEC_CAP_* bits.

pub fn profile_iter(&self) -> AvProfileIterator

Returns an iterator over the profiles supported by this codec.

pub fn pixel_format_iter(&self) -> AvPixelFormatIterator

Returns an iterator over the pixel formats supported by this codec.

For a decoder, the returned array will likely be empty. This means that ffmpeg’s native pixel format (YUV420) will be used.

pub fn build_encoder(&self) -> Result<EncoderContextBuilder, AvCodecOpenError>

Get a builder for a encoder AvCodecContext using this codec.

pub fn build_decoder(&self) -> Result<DecoderContextBuilder, AvCodecOpenError>

Get a builder for a decoder AvCodecContext using this codec.

fn alloc_context(&self) -> Result<AvCodecContext, AvCodecOpenError>

Internal helper for build_decoder to allocate an AvCodecContext. This needs to be paired with a later call to AvCodecContext::init.
