VideoCodec

enum VideoCodec : Enum<VideoCodec> (source)

A video codec filmstrip can produce, whether by asking a device's hardware encoder for it or by copying it across from a source untouched.

H.264 is encodable everywhere and HEVC almost everywhere. VP9 is a browser encode target too. The rest are never an encode target on any backend today and only ever reach an output by copy.

Entries

Auto

Let filmstrip choose, preferring the source's codec when the device can encode it.

MatchSource

Encode with the first clip's own codec when the device can, otherwise fall back through the same order as Auto and report the fallback. A composition with no source codec to name, such as one of only stills, takes that order with nothing reported. Unlike any other named codec it does not block a stream copy.

H264

H.264, also known as AVC.

Hevc

HEVC, also known as H.265.

Vp9

VP9. Browser encoders report it slightly more often than H.264, and no mobile backend offers it today.

Vp8

VP8. No backend encodes it, so it only ever reaches an output by copy.

Av1

AV1. No backend encodes it, so it only ever reaches an output by copy.

Properties

entries

val entries: EnumEntries<VideoCodec>

Returns a representation of an immutable list of all enum entries, in the order they're declared.

name

expect val name: String

ordinal

expect val ordinal: Int

Functions

valueOf

fun valueOf(value: String): VideoCodec

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

values

fun values(): Array<VideoCodec>

Returns an array containing the constants of this enum type, in the order they're declared.
