Answer 1

You use cacheDataSource created using cache and dataSource. This cacheDataSource is then used by ExtractorSampleSource.Below is the code for audioRenderer, similarly can be done for videoRender; passing to exoplayerInstance.prepare(renderers).

Cache cache = new SimpleCache(mCtx.getCacheDir(), new LeastRecentlyUsedCacheEvictor(1024 * 1024 * 10));
DataSource dataSource = new DefaultUriDataSource(mCtx, "My Player");
CacheDataSource cacheDataSource = new CacheDataSource(cache, dataSource, false, false);
Allocator allocator = new DefaultAllocator(BUFFER_SEGMENT_SIZE);
ExtractorSampleSource extractorSampleSource = new ExtractorSampleSource(trackURI, cacheDataSource, allocator, BUFFER_SEGMENT_COUNT*BUFFER_SEGMENT_SIZE, new Mp3Extractor());
MediaCodecAudioTrackRenderer audioTrackRenderer = new MediaCodecAudioTrackRenderer(extractorSampleSource);
