StreamInfo

data class StreamInfo(val index: Int, val type: MediaType, val codec: CodecId, val timeBase: Rational, val durationMicros: Long?, val bitrateBps: Long?, val video: VideoStreamInfo? = null, val audio: AudioStreamInfo? = null, val metadata: Map<String, String> = emptyMap(), val disposition: Disposition = Disposition.None, val rotationDegrees: Int = 0, val startTimeMicros: Long = 0, val codecExtradata: ByteArray? = null, val codecProfile: Int? = null, val mirrored: Boolean = false)

Read-only snapshot of an input stream's metadata.

Constructors

StreamInfo

constructor(index: Int, type: MediaType, codec: CodecId, timeBase: Rational, durationMicros: Long?, bitrateBps: Long?, video: VideoStreamInfo? = null, audio: AudioStreamInfo? = null, metadata: Map<String, String> = emptyMap(), disposition: Disposition = Disposition.None, rotationDegrees: Int = 0, startTimeMicros: Long = 0, codecExtradata: ByteArray? = null, codecProfile: Int? = null, mirrored: Boolean = false)

Properties

audio

val audio: AudioStreamInfo?

bitrateBps

val bitrateBps: Long?

codec

val codec: CodecId

codecExtradata

val codecExtradata: ByteArray?

An owned copy of the codec configuration carried by the container, such as an avcC or hvcC record. Null when the stream has no separate configuration record.

codecProfile

val codecProfile: Int?

FFmpeg's profile number for this stream's codec, one of the AV_PROFILE_* values in libavcodec/defs.h: for example 30 for E-AC-3 with Atmos, 60 for DTS-HD Master Audio or 1 for AAC LC. Null when neither the container nor the probe determined one.

disposition

val disposition: Disposition

What the container says this stream is for. Needed to mark or auto-select forced subtitles.

durationMicros

val durationMicros: Long?

index

val index: Int

language

val language: String?

BCP 47 or the raw three letter code, whichever the container provided. Null when absent.

metadata

val metadata: Map<String, String>

Per-stream tags: language (eng, jpn, …), title, handler_name, … as the stream stated them at open. Tags the stream brings later, such as the comments of a chained Ogg's next song, arrive on its packets as Packet.newStreamTags.

mirrored

val mirrored: Boolean

True when the display matrix also mirrors the picture. A renderer mirrors it left to right first, and then turns it clockwise by rotationDegrees. A front camera can record this way.

rotationDegrees

val rotationDegrees: Int

Clockwise rotation a renderer must apply, in degrees, from the container's display matrix.

startTimeMicros

val startTimeMicros: Long

Where this stream's own timeline starts, in microseconds. May differ from the container's.

timeBase

val timeBase: Rational

title

val title: String?

type

val type: MediaType
