fun build(): TvTrackInfo

Creates a TvTrackInfo instance with the specified fields.

setAudioChannelCount

fun setAudioChannelCount(audioChannelCount: Int): TvTrackInfo.Builder

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

setAudioDescription

fun setAudioDescription(audioDescription: Boolean): TvTrackInfo.Builder

Sets the audio description attribute of the audio. 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).

setAudioSampleRate

fun setAudioSampleRate(audioSampleRate: Int): TvTrackInfo.Builder

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

setDescription

fun setDescription(description: CharSequence): TvTrackInfo.Builder

Sets a user readable description for the current track.

setEncoding

fun setEncoding(encoding: String?): TvTrackInfo.Builder

Sets the encoding of the track.

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).

setEncrypted

fun setEncrypted(encrypted: Boolean): TvTrackInfo.Builder

Sets the encryption status of the track.

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

setExtra

fun setExtra(extra: Bundle): TvTrackInfo.Builder

Sets the extra information about the current track.

setHardOfHearing

fun setHardOfHearing(hardOfHearing: Boolean): TvTrackInfo.Builder

Sets the hard of hearing attribute of the track. 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).

setLanguage

fun setLanguage(language: String): TvTrackInfo.Builder

Sets the language information of the current track.

setSpokenSubtitle

fun setSpokenSubtitle(spokenSubtitle: Boolean): TvTrackInfo.Builder

Sets the spoken subtitle attribute of the audio. 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).

setVideoActiveFormatDescription

fun setVideoActiveFormatDescription(videoActiveFormatDescription: Byte): TvTrackInfo.Builder

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

This is needed for applications to be able to scale the video properly based on the information about where in the coded picture the active video is. 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.

setVideoFrameRate

fun setVideoFrameRate(videoFrameRate: Float): TvTrackInfo.Builder

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

setVideoHeight

fun setVideoHeight(videoHeight: Int): TvTrackInfo.Builder

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

setVideoPixelAspectRatio

fun setVideoPixelAspectRatio(videoPixelAspectRatio: Float): TvTrackInfo.Builder

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

This is needed for applications to be able to scale the video properly for some video formats such as 720x576 4:3 and 720x576 16:9 where pixels are not square. By default, applications assume the value of 1.0 (square pixels), so it is not necessary to set the pixel aspect ratio for most video formats.

setVideoWidth

fun setVideoWidth(videoWidth: Int): TvTrackInfo.Builder

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