有没有在Exoplayer2上实现“低速”清理的解决方案？

File cacheDirectory = new File(context.getCacheDir(), "exoplayer_cache");
Cache cache = new SimpleCache(cacheDirectory, new LeastRecentlyUsedCacheEvictor(100 * 1024 * 1024)); // 设置缓存大小为100MB

DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(context, Util.getUserAgent(context, "YourApplicationName"));

CacheDataSource.Factory cacheDataSourceFactory = new CacheDataSourceFactory(cache, dataSourceFactory);
cacheDataSourceFactory.setCacheWriteDataSinkFactory(null); // 禁用写入缓存
cacheDataSourceFactory.setCacheReadDataSourceFactory(dataSourceFactory); // 设置读取缓存时使用的数据源
cacheDataSourceFactory.setFlags(CacheDataSource.FLAG_IGNORE_CACHE_ON_ERROR); // 忽略缓存错误
cacheDataSourceFactory.setCacheKeyFactory(new CacheKeyFactory() {
    @Override
    public String buildCacheKey(DataSpec dataSpec) {
        // 自定义缓存键的生成方式，可以根据需要进行调整
        return dataSpec.uri.toString();
    }
});

MediaSource mediaSource = new ProgressiveMediaSource.Factory(cacheDataSourceFactory).createMediaSource(mediaItem);
player.setMediaSource(mediaSource);
