Question

因此，我试图在ExoPlayer 2上播放一些HLS。它工作正常，但突然出现403错误。当我在野生动物园上运行url（“ http://open.live.bbc.co.uk/mediaselector/5/redir/version/2.0/vpid/b0bbnbp9/mediaset/audio-syndication/proto/http”）时，它可以正常工作，但是当我在Android应用中尝试该网址时却无法正常工作。

val bandwidthMeter = DefaultBandwidthMeter()
    val extractorsFactory = DefaultExtractorsFactory()
    val trackSelectionFactory = AdaptiveTrackSelection.Factory(bandwidthMeter)
    val trackSelector = DefaultTrackSelector(trackSelectionFactory)

    val userAgent: String = Util.getUserAgent(applicationContext, "mediaPlayerSample")
    val httpDataSourceFactory = DefaultHttpDataSourceFactory(
            userAgent,
            null,
            DefaultHttpDataSource.DEFAULT_CONNECT_TIMEOUT_MILLIS,
            DefaultHttpDataSource.DEFAULT_READ_TIMEOUT_MILLIS,
            true
    )
val mediaSource = ExtractorMediaSource.Factory(httpDataSourceFactory).setExtractorsFactory(extractorsFactory).createMediaSource(Uri.parse(url))
        mPlayer = ExoPlayerFactory.newSimpleInstance(this, trackSelector)
        mPlayer.seekTo(contentPosition)
        mPlayer.prepare(mediaSource)
mPlayer.playWhenReady = true

错误消息：

Answer 1

您的代码似乎很完美，只是您需要更改代码：

val mediaSource = ExtractorMediaSource.Factory(httpDataSourceFactory).setExtractorsFactory(extractorsFactory).createMediaSource(Uri.parse(url))

收件人，更新以下代码：

HlsMediaSource hlsMediaSource = new HlsMediaSource(Uri.parse(url),httpDataSourceFactory, 1800000,new Handler(), null);

mPlayer.prepare(hlsMediaSource)

Answer 2

播放器提供源错误，因为您提供给播放器的网址不是有效的hls网址。

Safari能够播放文件，因为它可以找出实际的重定向URL并播放。

您提供的网址实际上是重定向到：

http://cp401492-vh.akamaihd.net/i/prod_af_mp4_heaacv1_48/iplayerstream/l2o/b0bbnbp9_22abe4cc-c52b-4cf5-a785-e7803e1fdd9a.mp4/master.m3u8?hdnea=st=1532432045~exp=1532453645~acl=/b0bbnbp9_22abe4cc-c52b-4cf5-a785-e7803e1fdd9a.mp4~hmac=0fe4da8ddc4bc2dacd92865be29097d0a251cfa3489a7c56603563a268fe2c21

这是有效的hls网址（具有m3u8文件）。尝试在exoplayer上播放它，它应该可以工作

编辑：

您可以通过将allowCrossProtocolRedirects = true传递给DefaultUriDataSource构造函数来在ExoPlayer中启用跨协议重定向。
