There are usually 3 types of videos while streaming in any Video Player. While working on Android TV we categorize these in<\/p>\n
Dash Videos<\/span><\/p>\n<\/li>\n HLS Videos (.m3u8 & .ts)<\/span><\/p>\n<\/li>\n Others (.mp4,.mpeg etc)<\/span><\/p>\n<\/li>\n<\/ol>\n We need different types of ExtractorRendererBuilder for playing different videos with Exo-Player. In this article I will be describing the difference between Other Videosand HLS Videos (.m3u8 & .ts).<\/span><\/p>\n For HLS Videos we need to create different ExtractorRenderBuilder for reference I will be taking them as HlsExtractorRendererBuilder<\/strong> and ExtractorRendererBuilder<\/strong> respectively.<\/p>\n In PlaybackFragment getRendererBuilder()<\/em> method will be implemented somewhat like this<\/p>\n [java]private VideoPlayer.RendererBuilder getRendererBuilder() { userAgent : Util.getUserAgent() gives ExoVideoPlayer which tells that what kind of VideoPlayer we are going to use. Internal implementation of getUserAgent() is<\/p>\n [java] ContentUri :<\/strong> Video Url to be played<\/p>\n contentType :<\/strong> Util.inferContentType() extracts the video type. Internal implementation of inferContentType() is<\/p>\n [java]public static int inferContentType(String fileName) { Playing TYPE_OTHER Videos in ExoPlayer<\/p>\n The buildRenderers() for TYPE_OTHER videos would be as following code.<\/p>\n [java] public void buildRenderers(VideoPlayer player) {<\/p>\n Allocator allocator = new DefaultAllocator(BUFFER_SEGMENT_SIZE);<\/p>\n Handler mainHandler = player.getMainHandler();<\/p>\n \/\/ Build the video and audio renderers.<\/p>\n DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter(mainHandler, null);<\/p>\n DataSource dataSource = new DefaultUriDataSource(context, bandwidthMeter, userAgent);<\/p>\n ExtractorSampleSource sampleSource = new ExtractorSampleSource(uri, dataSource, allocator,<\/p>\n BUFFER_SEGMENT_COUNT * BUFFER_SEGMENT_SIZE, mainHandler, player, 0);<\/p>\n MediaCodecVideoTrackRenderer videoRenderer = new MediaCodecVideoTrackRenderer(context,<\/p>\n sampleSource, MediaCodecSelector.DEFAULT, MediaCodec.VIDEO_SCALING_MODE_SCALE_TO_FIT, 5000,<\/p>\n mainHandler, player, 50);<\/p>\n MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(sampleSource,<\/p>\n MediaCodecSelector.DEFAULT, null, true, mainHandler, player,<\/p>\n AudioCapabilities.getCapabilities(context), AudioManager.STREAM_MUSIC);<\/p>\n TrackRenderer textRenderer = new TextTrackRenderer(sampleSource, player,<\/p>\n mainHandler.getLooper());<\/p>\n \/\/ Invoke the callback.<\/p>\n TrackRenderer[] renderers = new TrackRenderer[VideoPlayer.RENDERER_COUNT];<\/p>\n renderers[VideoPlayer .TYPE_VIDEO] = videoRenderer;<\/p>\n renderers[VideoPlayer .TYPE_AUDIO] = audioRenderer;<\/p>\n renderers[VideoPlayer .TYPE_TEXT] = textRenderer;<\/p>\n player.onRenderers(renderers, bandwidthMeter);<\/p>\n } We include Video, Audio, Text types of renderer as per our need.<\/p>\n [java] public void cancel() {<\/p>\n \/\/Do Nothing<\/p>\n } Playing TYPE_HLS Videos in ExoPlayer<\/p>\n As we know that HLS stands for HTTP Live Streaming, So we need to implement AsyncRendererBuilder for streaming HLS type of Videos.<\/p>\n BuildRenderers() for HLS Videos :<\/p>\n [java] public void buildRenderers(DemoPlayer player) {<\/p>\n currentAsyncBuilder = new AsyncRendererBuilder(context, userAgent, url, player);<\/p>\n currentAsyncBuilder.init();<\/p>\n } Cancel() fir HLS Videos:<\/p>\n [java]@Override<\/p>\n public void cancel() {<\/p>\n if (currentAsyncBuilder != null) {<\/p>\n currentAsyncBuilder.cancel();<\/p>\n currentAsyncBuilder = null;<\/p>\n }<\/p>\n
\n String userAgent = Util.getUserAgent(getContext(), "ExoVideoPlayer");
\n Uri contentUri = Uri.parse(mSelectedVideo.videoUrl);
\n int contentType = Util.inferContentType(contentUri.getLastPathSegment());
\n switch (contentType) {
\n case Util.TYPE_OTHER: {
\n return new ExtractorRendererBuilder(getContext(), userAgent, contentUri);
\n }
\n case Util.TYPE_HLS: {
\n return new HlsExtractorRendererBuilder(getContext(), userAgent, contentUri);
\n }
\n default: {
\nthrow new IllegalStateException("Unsupported type: " + contentType);
\n }
\n }
\n}
\n[\/java]<\/p>\n
\npublic static String getUserAgent(Context context, String applicationName) {
\n String versionName;
\n try {
\n String packageName = context.getPackageName();
\n PackageInfo info = context.getPackageManager().getPackageInfo(packageName, 0);
\n versionName = info.versionName;
\n } catch (NameNotFoundException e) {
\n versionName = "?";
\n }
\n return applicationName + "\/" + versionName + " (Linux;Android " + Build.VERSION.RELEASE
\n + ") " + "ExoPlayerLib\/" + ExoPlayerLibraryInfo.VERSION;
\n}
\n[\/java]<\/p>\n
\nif (fileName == null) {
\nreturn TYPE_OTHER;
\n} else if (fileName.endsWith(".mpd")) {
\nreturn TYPE_DASH;
\n} else if (fileName.endsWith(".ism")) {
\nreturn TYPE_SS;
\n} else if (fileName.endsWith(".m3u8")) {
\nreturn TYPE_HLS;
\n} else {
\nreturn TYPE_OTHER;
\n}
\n}

\nFor playing different type of videos we create different rendererbuilders, Each RenderBuilder class implements RenderBuilder interface and we need to implement buildRenderers() and cancel() methods.<\/p>\n
