Java DefaultAllocator类代码示例

import com.google.android.exoplayer2.upstream.DefaultAllocator; //导入依赖的package包/类
/**
 * Constructs a new instance.
 *
 * @param allocator The {@link DefaultAllocator} used by the loader.
 * @param minBufferMs The minimum duration of media that the player will attempt to ensure is
 *     buffered at all times, in milliseconds.
 * @param maxBufferMs The maximum duration of media that the player will attempt buffer, in
 *     milliseconds.
 * @param bufferForPlaybackMs The duration of media that must be buffered for playback to start or
 *     resume following a user action such as a seek, in milliseconds.
 * @param bufferForPlaybackAfterRebufferMs The default duration of media that must be buffered for
 *     playback to resume after a rebuffer, in milliseconds. A rebuffer is defined to be caused by
 *     buffer depletion rather than a user action.
 * @param targetBufferBytes The target buffer size in bytes. If set to {@link C#LENGTH_UNSET}, the
 *     target buffer size will be calculated using {@link #calculateTargetBufferSize(Renderer[],
 *     TrackSelectionArray)}.
 * @param prioritizeTimeOverSizeThresholds Whether the load control prioritizes buffer time
