static val TYPE_SUBTITLE: Int

The type value for subtitle tracks.

Value: 2

TYPE_VIDEO

static val TYPE_VIDEO: Int

Value: 1

describeContents

fun describeContents(): Int

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel,int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

equals

fun equals(other: Any?): Boolean

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

getAudioChannelCount

fun getAudioChannelCount(): Int

Returns the audio channel count. Valid only for TYPE_AUDIO tracks.

getAudioSampleRate

fun getAudioSampleRate(): Int

Returns the audio sample rate, in the unit of Hz. Valid only for TYPE_AUDIO tracks.

getDescription

fun getDescription(): CharSequence!

Returns a user readable description for the current track.

getEncoding

fun getEncoding(): String?

Returns the codec in the form of mime type. If the encoding is unknown or could not be determined, the corresponding value will be null.

For example of broadcast, codec information may be referred to broadcast standard (e.g. Component Descriptor of ETSI EN 300 468). In the case that track type is subtitle, mime type could be defined in broadcast standard (e.g. "text/dvb.subtitle" or "text/dvb.teletext" in ETSI TS 102 812 V1.3.1 section 7.6).

getExtra

fun getExtra(): Bundle!

Returns the extra information about the current track.

getId

fun getId(): String!

Returns the ID of the track.

getLanguage

fun getLanguage(): String!

Returns the language information encoded by either ISO 639-1 or ISO 639-2/T. If the language is unknown or could not be determined, the corresponding value will be null.

getType

fun getType(): Int

Returns the type of the track. The type should be one of the followings: TYPE_AUDIO, TYPE_VIDEO and TYPE_SUBTITLE.

getVideoActiveFormatDescription

fun getVideoActiveFormatDescription(): Byte

Returns the Active Format Description (AFD) code of the video. Valid only for TYPE_VIDEO tracks.

The complete list of values are defined in ETSI TS 101 154 V1.7.1 Annex B, ATSC A/53 Part 4 and SMPTE 2016-1-2007.

getVideoFrameRate

fun getVideoFrameRate(): Float

Returns the frame rate of the video, in the unit of fps (frames per second). Valid only for TYPE_VIDEO tracks.

getVideoHeight

fun getVideoHeight(): Int

Returns the height of the video, in the unit of pixels. Valid only for TYPE_VIDEO tracks.

getVideoPixelAspectRatio

fun getVideoPixelAspectRatio(): Float

Returns the pixel aspect ratio (the ratio of a pixel's width to its height) of the video. Valid only for TYPE_VIDEO tracks.

getVideoWidth

fun getVideoWidth(): Int

Returns the width of the video, in the unit of pixels. Valid only for TYPE_VIDEO tracks.

hashCode

fun hashCode(): Int

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

isAudioDescription

fun isAudioDescription(): Boolean

Returns true if the track is an audio description intended for people with visual impairment, false otherwise. Valid only for TYPE_AUDIO tracks.

For example of broadcast, audio description information may be referred to broadcast standard (e.g. ISO 639 Language Descriptor of ISO/IEC 13818-1, Supplementary Audio Language Descriptor, AC-3 Descriptor, Enhanced AC-3 Descriptor, AAC Descriptor of ETSI EN 300 468).

isEncrypted

fun isEncrypted(): Boolean

Returns true if the track is encrypted, false otherwise. If the encryption status is unknown or could not be determined, the corresponding value will be false.

For example: ISO/IEC 13818-1 defines a CA descriptor that can be used to determine the encryption status of some broadcast streams.

isHardOfHearing

fun isHardOfHearing(): Boolean

Returns true if the track is intended for people with hearing impairment, false otherwise. Valid only for TYPE_AUDIO and TYPE_SUBTITLE tracks.

For example of broadcast, hard of hearing information may be referred to broadcast standard (e.g. ISO 639 Language Descriptor of ISO/IEC 13818-1, Supplementary Audio Language Descriptor, AC-3 Descriptor, Enhanced AC-3 Descriptor, AAC Descriptor of ETSI EN 300 468).

isSpokenSubtitle

fun isSpokenSubtitle(): Boolean

Returns true if the track is a spoken subtitle for people with visual impairment, false otherwise. Valid only for TYPE_AUDIO tracks.

For example of broadcast, spoken subtitle information may be referred to broadcast standard (e.g. Supplementary Audio Language Descriptor of ETSI EN 300 468).

writeToParcel

fun writeToParcel(
    dest: Parcel, 
    flags: Int
): Unit

Used to package this object into a Parcel.
