Example 1 with FileDataSource

use of com.google.android.exoplayer2.upstream.FileDataSource in project ExoPlayer by google.

the class CacheDataSourceTest2 method buildCacheDataSource.

private static CacheDataSource buildCacheDataSource(Context context, DataSource upstreamSource, boolean useAesEncryption) throws CacheException {
    File cacheDir = context.getExternalCacheDir();
    Cache cache = new SimpleCache(new File(cacheDir, EXO_CACHE_DIR), new NoOpCacheEvictor());
    emptyCache(cache);
    // Source and cipher
    final String secretKey = "testKey:12345678";
    DataSource file = new FileDataSource();
    DataSource cacheReadDataSource = useAesEncryption ? new AesCipherDataSource(Util.getUtf8Bytes(secretKey), file) : file;
    // Sink and cipher
    CacheDataSink cacheSink = new CacheDataSink(cache, EXO_CACHE_MAX_FILESIZE);
    byte[] scratch = new byte[3897];
    DataSink cacheWriteDataSink = useAesEncryption ? new AesCipherDataSink(Util.getUtf8Bytes(secretKey), cacheSink, scratch) : cacheSink;
    return new CacheDataSource(cache, upstreamSource, cacheReadDataSource, cacheWriteDataSink, CacheDataSource.FLAG_BLOCK_ON_CACHE, // eventListener
    null);
}

Example 2 with FileDataSource

use of com.google.android.exoplayer2.upstream.FileDataSource in project ExoPlayer by google.

the class CacheDataSourceTest method createCacheDataSource.

private CacheDataSource createCacheDataSource(boolean setReadException, boolean simulateUnknownLength, @CacheDataSource.Flags int flags, CacheDataSink cacheWriteDataSink) {
    FakeDataSource.Builder builder = new FakeDataSource.Builder();
    if (setReadException) {
        builder.appendReadError(new IOException("Shouldn't read from upstream"));
    }
    FakeDataSource upstream = builder.setSimulateUnknownLength(simulateUnknownLength).appendReadData(TEST_DATA).build();
    return new CacheDataSource(simpleCache, upstream, new FileDataSource(), cacheWriteDataSink, flags, null);
