Recyclerview中的Exoplayer错误，源错误没有可用的提取器 [英] Exoplayer error in Recyclerview, Source error None of the available extractors

问题描述

我正在使用ExoPlayer在RecyclerView中流式传输视频.

I am using ExoPlayer to stream videos in a RecyclerView.

我正在ViewHolder的RecyclerView Adapter的bind方法中实现ExoPlayer.

I am implementing the ExoPlayer inside my RecyclerView Adapter's bind method inside my ViewHolder.

我正在使用的视频格式是m3u8，我正在使用的URL在浏览器中有效.所以我知道视频链接是有效的.我也在其中测试了一个youtube链接.

The video format I am using is m3u8 and the URL I am using works in a browser. So I know that the video link is valid. I've also testing a youtube link in there.

这是Recyclerview适配器的ViewHolder->

Here is the code from the Recyclerview adapter's ViewHolder ->

class ViewHolder private constructor(val binding: FeedRowBinding) :
    RecyclerView.ViewHolder(binding.root) {

    fun bind(context: Activity){
        if (entity.content.videolink != null) {
            setupVideoPlayer(entity.content.videolink, context)
        }
    }
}

private fun setupVideoPlayer(url: String, context: Activity) {
    val videoExoPlayer = SimpleExoPlayer.Builder(binding.videoView.context).build()
    videoExoPlayer.prepare(createUrlMediaSource(url, context))

    binding.play.setOnClickListener {
        videoExoPlayer.playWhenReady = true
    }

    binding.pause.setOnClickListener {
        videoExoPlayer.playWhenReady = false
    }
}

private fun createUrlMediaSource(url: String, context: Activity): MediaSource {
    val userAgent = Util.getUserAgent(context, context.getString(R.string.about))
    return ProgressiveMediaSource
           .Factory(DefaultDataSourceFactory(context, userAgent), DefaultExtractorsFactory())
           .createMediaSource(Uri.parse(url))
}

加载我的recyclerview并转到视频所在的行时，出现以下错误:

When loading my recyclerview and get to the row with the video I get the following error:

ExoPlayerImplInternal:源错误.com.google.android.exoplayer2.source.UnrecognizedInputFormatException:没有可用的提取器(MatroskaExtractor，FragmentedMp4Extractor，Mp4Extractor，Mp3Extractor，AdtsExtractor，Ac3Extractor，TsExtractor，FlvExtractor，OggExtractor，PsExtractor，WavExtractor，AmrExtractor，Ac4Extractor，FlacExtractor)可以读取流.在com.google.android.exoplayer2.source.ProgressiveMediaPeriod $ ExtractorHolder.selectExtractor(ProgressiveMediaPeriod.java:1090)在com.google.android.exoplayer2.source.ProgressiveMediaPeriod $ ExtractingLoadable.load(ProgressiveMediaPeriod.java:969)在com.google.android.exoplayer2.upstream.Loader $ LoadTask.run(Loader.java:391)在java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1162)在java.util.concurrent.ThreadPoolExecutor $ Worker.run(ThreadPoolExecutor.java:636)在java.lang.Thread.run(Thread.java:764)

我不确定我在做什么错，关于如何解决此问题的任何想法?

I'm not sure what am I doing wrong, any ideas on how to fix this issue?

推荐答案

您需要修改 createUrlMediaSource

private fun createUrlMediaSource(url: String, context: Activity): MediaSource {
    val userAgent = Util.getUserAgent(context, context.getString(R.string.about))
    return ProgressiveMediaSource
           .Factory(DefaultDataSourceFactory(context, userAgent), DefaultExtractorsFactory())
           .createMediaSource(Uri.parse(url))
}

如 https://exoplayer.dev

• DashMediaSource (用于DASH).
• SsMediaSource 用于SmoothStreaming.
• HlsMediaSource for HLS(这是您的格式=> .m3u8).
• ProgressiveMediaSource (用于常规媒体文件).

• DashMediaSource for DASH.
• SsMediaSource for SmoothStreaming.
• HlsMediaSource for HLS (this is your format => .m3u8).
• ProgressiveMediaSource for regular media files.

因此，您需要将函数替换为此:

So you need to replace your function to this:

private fun createUrlMediaSource(url: String, context: Activity): MediaSource {
    val userAgent = Util.getUserAgent(context, context.getString(R.string.about))
    return HlsMediaSource
           .Factory(DefaultDataSourceFactory(context, userAgent), DefaultExtractorsFactory())
           .createMediaSource(Uri.parse(url))
}
