MediaCodecInfo

const val MAX_SUPPORTED_INSTANCES_UNKNOWN = -1: Int

The value returned by getMaxSupportedInstances if the upper bound on the maximum number of supported instances is unknown.

const val TAG = "MediaCodecInfo": String!

fun alignVideoSizeV21(width: Int, height: Int): Point?

Returns the smallest video size greater than or equal to a specified size that also satisfies the MediaCodec's width and height alignment requirements.

fun canReuseCodec(oldFormat: Format!, newFormat: Format!): DecoderReuseEvaluation!

Evaluates whether it's possible to reuse an instance of this decoder that's currently decoding oldFormat to decode newFormat instead.

For adaptation to succeed, the codec must also be configured with maximum values that are compatible with the new format.

fun getMaxSupportedInstances(): Int

Returns an upper bound on the maximum number of supported instances, or MAX_SUPPORTED_INSTANCES_UNKNOWN if unknown. Applications should not expect to operate more instances than the returned maximum.

fun getProfileLevels(): Array<MediaCodecInfo.CodecProfileLevel!>!

The profile levels supported by the decoder.

fun isAudioChannelCountSupportedV21(channelCount: Int): Boolean

Whether the decoder supports audio with a given channel count.

fun isAudioSampleRateSupportedV21(sampleRate: Int): Boolean

Whether the decoder supports audio with a given sample rate.

fun isFormatFunctionallySupported(format: Format!): Boolean

Returns whether the decoder may functionally support decoding the given format.

fun isFormatSupported(format: Format!): Boolean

Returns whether the decoder may support decoding the given format both functionally and performantly.

fun isHdr10PlusOutOfBandMetadataSupported(): Boolean

Whether the codec handles HDR10+ out-of-band metadata.

fun isSeamlessAdaptationSupported(format: Format!): Boolean

Returns whether it may be possible to adapt an instance of this decoder to playing a different format when the codec is configured to play media in the specified format.

For adaptation to succeed, the codec must also be configured with appropriate maximum values and canReuseCodec must return true for the old/new formats.

fun isVideoSizeAndRateSupportedV21(width: Int, height: Int, frameRate: Double): Boolean

Whether the decoder supports video with a given width, height and frame rate.

java-static fun newInstance(

): MediaCodecInfo!

Creates an instance.

fun toString(): String!

val adaptive: Boolean

Whether the decoder supports seamless resolution switches.

val capabilities: MediaCodecInfo.CodecCapabilities?

The capabilities of the decoder, like the profiles/levels it supports, or null if not known.

val codecMimeType: String!

The MIME type that the codec uses for media of type mimeType. Equal to mimeType unless the codec is known to use a non-standard MIME type alias.

val detachedSurfaceSupported: Boolean

Whether the codec supports "detached" surface mode where it is able to decode without an attached surface. Only relevant for video codecs.

val hardwareAccelerated: Boolean

Whether the codec is hardware accelerated.

This could be an approximation as the exact information is only provided in API levels 29+.

val mimeType: String!

The MIME type handled by the codec.

val name: String!

The name of the decoder.

May be passed to createByCodecName to create an instance of the decoder.

val secure: Boolean

Whether the decoder is secure.

val softwareOnly: Boolean

Whether the codec is software only.

This could be an approximation as the exact information is only provided in API levels 29+.

val tunneling: Boolean

Whether the decoder supports tunneling.

val vendor: Boolean

Whether the codec is from the vendor.

This could be an approximation as the exact information is only provided in API levels 29+.
