Public constructors
Builder
public Builder (int type,
String id)
Create a Builder. Any field that should be included in the TvTrackInfo
must be added.
Public methods

int: The audio channel count. |
setAudioDescription
public TvTrackInfo.Builder setAudioDescription (boolean audioDescription)
Sets the audio description attribute of the audio. Valid only for TvTrackInfo.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).
| Parameters |
|---|
audioDescription |
boolean: The audio description attribute of the audio. |
setAudioSampleRate
public TvTrackInfo.Builder setAudioSampleRate (int audioSampleRate)
Sets the audio sample rate, in the unit of Hz. Valid only for TvTrackInfo.TYPE_AUDIO
tracks.
| Parameters |
|---|
audioSampleRate |
int: The audio sample rate. |
setDescription
public TvTrackInfo.Builder setDescription (CharSequence description)
Sets a user readable description for the current track.
| Parameters |
|---|
description |
CharSequence: The user readable description.
This value cannot be null. |
setEncoding
public TvTrackInfo.Builder setEncoding (String encoding)
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).
| Parameters |
|---|
encoding |
String: The encoding of the track in the form of mime type.
This value may be null. |
setEncrypted
public TvTrackInfo.Builder setEncrypted (boolean encrypted)
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.
| Parameters |
|---|
encrypted |
boolean: The encryption status of the track. |
setExtra
public TvTrackInfo.Builder setExtra (Bundle extra)
Sets the extra information about the current track.
| Parameters |
|---|
extra |
Bundle: The extra information.
This value cannot be null. |
setHardOfHearing
public TvTrackInfo.Builder setHardOfHearing (boolean hardOfHearing)
Sets the hard of hearing attribute of the track. Valid only for TvTrackInfo.TYPE_AUDIO and
TvTrackInfo.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).
| Parameters |
|---|
hardOfHearing |
boolean: The hard of hearing attribute of the track. |
setLanguage
public TvTrackInfo.Builder setLanguage (String language)
Sets the language information of the current track.
| Parameters |
|---|
language |
String: The language string encoded by either ISO 639-1 or ISO 639-2/T.
This value cannot be null. |
setSpokenSubtitle
public TvTrackInfo.Builder setSpokenSubtitle (boolean spokenSubtitle)
Sets the spoken subtitle attribute of the audio. Valid only for TvTrackInfo.TYPE_AUDIO
tracks.

standard (e.g. Supplementary Audio Language Descriptor of ETSI EN 300 468).
| Parameters |
|---|
spokenSubtitle |
boolean: The spoken subtitle attribute of the audio. |
public TvTrackInfo.Builder setVideoActiveFormatDescription (byte videoActiveFormatDescription)
Sets the Active Format Description (AFD) code of the video.
Valid only for TvTrackInfo.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.
| Parameters |
|---|
videoActiveFormatDescription |
byte: The AFD code of the video. |
setVideoFrameRate
public TvTrackInfo.Builder setVideoFrameRate (float videoFrameRate)
Sets the frame rate of the video, in the unit fps (frames per rate). Valid only for
TvTrackInfo.TYPE_VIDEO tracks.
| Parameters |
|---|
videoFrameRate |
float: The frame rate of the video. |
setVideoHeight
public TvTrackInfo.Builder setVideoHeight (int videoHeight)
Sets the height of the video, in the unit of pixels. Valid only for TvTrackInfo.TYPE_VIDEO
tracks.
| Parameters |
|---|
videoHeight |
int: The height of the video. |
setVideoPixelAspectRatio
public TvTrackInfo.Builder setVideoPixelAspectRatio (float videoPixelAspectRatio)
Sets the pixel aspect ratio (the ratio of a pixel's width to its height) of the video.
Valid only for TvTrackInfo.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.
| Parameters |
|---|
videoPixelAspectRatio |
float: The pixel aspect ratio of the video. |
setVideoWidth
public TvTrackInfo.Builder setVideoWidth (int videoWidth)
Sets the width of the video, in the unit of pixels. Valid only for TvTrackInfo.TYPE_VIDEO
tracks.
| Parameters |
|---|
videoWidth |
int: The width of the video. |
