Examples with Cache com.google.android.exoplayer2.upstream.cache.Cache used on opensource projects

Example 1 with Cache

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

the class CacheDataSourceTest method testUnsatisfiableRange.

public void testUnsatisfiableRange() throws Exception {
    // Bounded request but the content length is unknown. This forces all data to be cached but not
    // the length
    assertCacheAndRead(false, true);
    // Now do an unbounded request. This will read all of the data from cache and then try to read
    // more from upstream which will cause to a 416 so CDS will store the length.
    CacheDataSource cacheDataSource = createCacheDataSource(true, true);
    assertReadDataContentLength(cacheDataSource, true, true);
    // If the user try to access off range then it should throw an IOException
    try {
        cacheDataSource = createCacheDataSource(false, false);
        cacheDataSource.open(new DataSpec(Uri.EMPTY, TEST_DATA.length, 5, KEY_1));
        fail();
    } catch (IOException e) {
    // success
    }
}

Example 2 with Cache

    // Same DRM info as item1, but different URL to check it doesn't prevent re-using a manager.
    MediaItem mediaItem2 = new MediaItem.Builder().setUri("https://example.test/content-2").setDrmConfiguration(new MediaItem.DrmConfiguration.Builder(C.WIDEVINE_UUID).build()).build();

    // since we only cache one.
    DrmSessionManager drmSessionManager4 = provider.get(mediaItem1);
