Struct CarrierSubtitleStreamDecoder 

pub struct CarrierSubtitleStreamDecoder<C: FfmpegCarrier> { /* private fields */ }

mediadecode::SubtitleDecoder impl wrapping ffmpeg::decoder::Subtitle.

Subtitle decoders are stateless from FFmpeg’s perspective — each decode() call consumes one packet and produces zero-or-one AVSubtitle. The pending-frame buffer here is a one-slot queue so the trait’s send_packet / receive_frame split works.

Implementations

impl CarrierSubtitleStreamDecoder<View>

pub fn open( parameters: Parameters, time_base: Timebase, limits: DecoderLimits, ) -> Result<Self, SubtitleDecodeError>

Opens a subtitle decoder for parameters.

pub const fn time_base(&self) -> Timebase

The time base associated with the source stream.

pub const fn limits(&self) -> DecoderLimits

The budgets this decoder was opened with.

pub const fn inner(&self) -> &Subtitle

The wrapped decoder context.

impl CarrierSubtitleStreamDecoder<Owned>

pub fn open( parameters: Parameters, time_base: Timebase, limits: DecoderLimits, ) -> Result<Self, SubtitleDecodeError>

Opens a subtitle decoder for parameters.

pub const fn time_base(&self) -> Timebase

The time base associated with the source stream.

pub const fn limits(&self) -> DecoderLimits

The budgets this decoder was opened with.

pub const fn inner(&self) -> &Subtitle

The wrapped decoder context.
