Public Method Documentation

oa::Status oa::VideoDemuxer::close()

Explicit resource-release boundary. Reports local file close failures; pending packets are discarded and no container data is manufactured.

Returns

oa::Status

The declared return value.

oa::U64 oa::VideoDemuxer::formatGeneration()

No public source comment is attached to this declaration.

Returns

oa::U64

The declared return value.

const Av1Config & oa::VideoDemuxer::getAv1Config()

No public source comment is attached to this declaration.

Returns

const Av1Config &

The declared return value.

const AvcConfig & oa::VideoDemuxer::getAvcConfig()

Returns SPS+PPS concatenated as Annex-B (empty if not parsed). Caller prepends to the first IDR packet to bootstrap the decoder.

Returns

const AvcConfig &

The declared return value.

oa::U32 oa::VideoDemuxer::getCurrentSampleIndex()

index of the next sample readNextPacket() will read (0-based). After decoding sample N, this equals N+1. Used by Video for step-back.

Returns

oa::U32

The declared return value.

const HvcConfig & oa::VideoDemuxer::getHvcConfig()

No public source comment is attached to this declaration.

Returns

const HvcConfig &

The declared return value.

const VideoContainerInfo & oa::VideoDemuxer::getInfo()

get container info

Returns

const VideoContainerInfo &

The declared return value.

const VideoDemuxerStats & oa::VideoDemuxer::getStats()

No public source comment is attached to this declaration.

Returns

const VideoDemuxerStats &

The declared return value.

VideoProfile oa::VideoDemuxer::getVideoProfile()

get video profile for decoder creation

Returns

VideoProfile

The declared return value.

const Vp9Config & oa::VideoDemuxer::getVp9Config()

No public source comment is attached to this declaration.

Returns

const Vp9Config &

The declared return value.

bool oa::VideoDemuxer::isEos()

Check if end of stream

Returns

bool

The declared return value.

bool oa::VideoDemuxer::isLive()

No public source comment is attached to this declaration.

Returns

bool

The declared return value.

bool oa::VideoDemuxer::isSeekable()

No public source comment is attached to this declaration.

Returns

bool

The declared return value.

oa::Status oa::VideoDemuxer::readNextPacket(
	VideoPacket & outPacket
)

Parameters

outPacket

VideoPacket &

—

Returns

oa::Status

The declared return value.

oa::Result<oa::U64> oa::VideoDemuxer::samplePresentationTimestamp(
	oa::Usize inSampleIndex
)

Return one indexed sample's presentation timestamp without converting a signed composition offset to unsigned first. Malformed tables whose offset underflows DTS or whose positive offset overflows fail closed.

Parameters

inSampleIndex

oa::Usize

—

Returns

oa::Result<oa::U64>

The declared return value.

oa::Status oa::VideoDemuxer::seek(
	oa::U64 inTimestamp
)

seek to a specific timestamp (in stream timebase)

Parameters

inTimestamp

oa::U64

—

Returns

oa::Status

The declared return value.

static oa::Result<VideoDemuxer> oa::VideoDemuxer::open(
	oa::StringView inUri
)

open either a local path or a URL through one canonical source boundary.

Parameters

inUri

oa::StringView

—

Returns

oa::Result<VideoDemuxer>

The declared return value.

static oa::Result<VideoDemuxer> oa::VideoDemuxer::open(
	oa::StringView inUri,
	const VideoDemuxerConfig & inConfig
)

No public source comment is attached to this declaration.

Parameters

inUri

oa::StringView

—

inConfig

const VideoDemuxerConfig &

—

Returns

oa::Result<VideoDemuxer>

The declared return value.

static oa::Result<VideoContainerInfo> oa::VideoDemuxer::probe(
	const char * inPath
)

probe container info without opening full file

Parameters

inPath

const char *

—

Returns

oa::Result<VideoContainerInfo>

The declared return value.
