直播源码APP,基于google ExoPlayer 简单自定义播放界面
直播源码APP,基于google ExoPlayer 简单自定义播放界面实现的相关代码
1.直播源码AP基于google ExoPlayer播放m3u8,mp4等文件
简单自定义播放界面,新建一个Layout 布局文件命名为exo_playback_control_view,控件的id不能随便起, 要与exoPlayer原来PlaybackControlView的布局控件id,名称一致, 布局名称不一定是exo_playback_control_view,不过需要在SimpleExoPlayerView控件中添加一个: app:controller_layout_id="@layout/id" ,指定control的布局;如:
2.如果需要详细的自定义播放界面,需要直播源码AP重写SimpleExoPlayerView,和PlaybackControlView。
3.重要的类
/** * 监听播放状态 */ private final class ComponentListener implements ExoPlayer.EventListener { @Override public void onPlayerStateChanged(boolean playWhenReady, int playbackState) { switch (playbackState) { /** * The player is able to immediately /*play from its current position. The player will be playing if * {@link #getPlayWhenReady()} is true, and paused otherwise. */ case Player.STATE_READY:// showLoading(false); play(playWhenReady); break; /** * The player has finished playing the media. */ case Player.STATE_ENDED: showLoading(false); playDefault(); break; /** * The player does not have any media to play. */ case Player.STATE_IDLE: showLoading(true); break; /** * The player is not able to /*immediately play from its current position. This state typically * occurs when more data needs to be loaded. */ case Player.STATE_BUFFERING: showLoading(true); break; } } @Override public void onRepeatModeChanged(int repeatMode) { // Do nothing. } @Override public void onPositionDiscontinuity() { // Do nothing. } @Override public void onPlaybackParametersChanged(PlaybackParameters playbackParameters) { // Do nothing. } @Override public void onTimelineChanged(Timeline timeline, Object manifest) { // Do nothing. } @Override public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) { // Do nothing. } @Override public void onLoadingChanged(boolean isLoading) { // Do nothing. } @Override public void onPlayerError(ExoPlaybackException error) { // Do nothing. } }
4.重要的方法:
/** * 根据不同的Uri文件,生成不同的MediaSource * * @param uri * @param overrideExtension * @return */ private MediaSource buildMediaSource(Uri uri, String overrideExtension) { int type = Util.inferContentType(!TextUtils.isEmpty(overrideExtension) ? "." + overrideExtension : uri.getLastPathSegment()); switch (type) { case C.TYPE_SS: return new SsMediaSource(uri, buildDataSourceFactory(false), new DefaultSsChunkSource.Factory(mediaDataSourceFactory), null, null); case C.TYPE_DASH: return new DashMediaSource(uri, buildDataSourceFactory(false), new DefaultDashChunkSource.Factory(mediaDataSourceFactory), null, null); case C.TYPE_HLS: return new HlsMediaSource(uri, mediaDataSourceFactory, null, null); case C.TYPE_OTHER: return new ExtractorMediaSource(uri, mediaDataSourceFactory, new DefaultExtractorsFactory(), null, null); default: { throw new IllegalStateException("Unsupported type: " + type); } } }
