@UnstableApi
val hasPrerollSamples: Boolean

Indicates whether the stream contains preroll samples.

When this field is set to true, it means that the stream includes decode-only samples that occur before the intended playback start position. These samples are necessary for decoding but are not meant to be rendered and should be skipped after decoding.

val height: Int

• SmoothStreaming track elements: Always NO_VALUE.
• Progressive container formats: Often NO_VALUE, but may be populated with the peak bitrate of the container if known.
• Sample formats: Often NO_VALUE, but may be populated with the peak bitrate of the stream of samples with type sampleMimeType if known. Note that if sampleMimeType is a compressed format (e.g., AUDIO_AAC), then this bitrate is for the stream of still compressed samples.
