Exoplayer AAC（ADTS/ADTS）/ AMR media duration
2023-10-09
Exoplayer 对于 AAC（ADTS/ADTS），AMR 默认不支持时长以及定位解析，如果有需求，需要自行开启恒定比特率定位：
DefaultExtractorsFactory().setConstantBitrateSeekingEnabled(true)
应用于构建函数第二个参数：
SimpleExoPlayer.Builder(context, DefaultExtractorsFactory().setConstantBitrateSeekingEnabled(true))
.build()
使用时通过 Listener 在 STATE_READY 状态进行获取，默认为 ms ：
var playerListener: Player.Listener = object : Player.Listener {
override fun onPlaybackStateChanged(state: Int) {
if (state == ExoPlayer.STATE_READY) {
val duration = mPlayer?.duration ?: 0L
val length = if (duration < 0) {
0L
} else {
duration / 1000
}
listener?.onAudioLength(length)
} else {
if (state == Player.STATE_ENDED) {
listener?.onComplete()
}
}
}
