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

setVideoActiveFormatDescription
TvTrackInfo.Builder setVideoActiveFormatDescription (byte videoActiveFormatDescription)
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.
| Parameters |
|---|
videoActiveFormatDescription |
byte:
The AFD code of the video. |
setVideoFrameRate
TvTrackInfo.Builder setVideoFrameRate (float videoFrameRate)
Sets the frame rate of the video, in the unit fps (frames per rate). Valid only for
TYPE_VIDEO tracks.
| Parameters |
|---|
videoFrameRate |
float:
The frame rate of the video. |
setVideoHeight
TvTrackInfo.Builder setVideoHeight (int videoHeight)
Sets the height of the video, in the unit of pixels. Valid only for TYPE_VIDEO
tracks.
| Parameters |
|---|
videoHeight |
int:
The height of the video. |
setVideoPixelAspectRatio
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 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
TvTrackInfo.Builder setVideoWidth (int videoWidth)
Sets the width of the video, in the unit of pixels. Valid only for TYPE_VIDEO
tracks.
| Parameters |
|---|
videoWidth |
int:
The width of the video. |
