在互联网上没有提到用户代理究竟是什么,我将传递什么作为其价值以及它用于什么。没有文档,没有。 另外,我如何获得" videoRepresentations"它是什么?
// Build the video renderer.
DataSource videoDataSource = new HttpDataSource(userAgent, HttpDataSource.REJECT_PAYWALL_TYPES, bandwidthMeter);
ChunkSource videoChunkSource = new DashChunkSource(videoDataSource, new AdaptiveEvaluator(bandwidthMeter), videoRepresentations);
ChunkSampleSource videoSampleSource = new ChunkSampleSource(videoChunkSource, loadControl, VIDEO_BUFFER_SEGMENTS * BUFFER_SEGMENT_SIZE, true);
MediaCodecVideoTrackRenderer videoRenderer = new MediaCodecVideoTrackRenderer(videoSampleSource, null, true, MediaCodec.VIDEO_SCALING_MODE_SCALE_TO_FIT, 0, mainHandler, playerActivity, 50);
// Build the audio renderer.
DataSource audioDataSource = new HttpDataSource(userAgent, HttpDataSource.REJECT_PAYWALL_TYPES, bandwidthMeter);
ChunkSource audioChunkSource = new DashChunkSource(audioDataSource, new FormatEvaluator.FixedEvaluator(), audioRepresentation);
SampleSource audioSampleSource = new ChunkSampleSource(audioChunkSource, loadControl, AUDIO_BUFFER_SEGMENTS * BUFFER_SEGMENT_SIZE, true);
MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(audioSampleSource, null, true);
文档非常不足 http://developer.android.com/guide/topics/media/exoplayer.html
答案 0 :(得分:1)
<强>的userAgent 强>
private RendererBuilder getRendererBuilder() {
String userAgent = DemoUtil.getUserAgent(this);
switch (contentType) {
case DemoUtil.TYPE_SS:
return new SmoothStreamingRendererBuilder(userAgent, contentUri.toString(), contentId,
new SmoothStreamingTestMediaDrmCallback(), debugTextView);
case DemoUtil.TYPE_DASH:
return new DashRendererBuilder(userAgent, contentUri.toString(), contentId,
new WidevineTestMediaDrmCallback(contentId), debugTextView);
default:
return new DefaultRendererBuilder(this, contentUri, debugTextView);
}
}
