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

Example 1 with CacheDataSource

use of com.google.android.exoplayer2.upstream.cache.CacheDataSource 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
    }
}
