MediaPlayer，仅视频m3u8 HTML流有效 [英] MediaPlayer, only video m3u8 HTML streams work

问题描述

我正在将MediaPlayer与m3u8音频流一起使用.这将导致出现日志错误消息:Error(1, -1010)

I'm using the MediaPlayer with a m3u8 audio stream. This results in a log error message: Error(1, -1010)

当我查看错误代码时，第一个参数似乎正确:

The first argument seems ok when I look at the error codes: https://github.com/android/platform_external_opencore/blob/master/pvmi/pvmf/include/pvmf_return_codes.h

只有-1010很奇怪.

当我使用苹果视频m3u8网址时，效果很好！这是网址: http://devimages.apple.com/iphone/samples/bipbop/gear1 /prog_index.m3u8

When I use the apple video m3u8 url it's working great! This is the url: http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8

我使用的代码很简单:

MediaPlayer mediaPlayer = new MediaPlayer();
try {
    mediaPlayer.setDataSource("http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8");
    mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    mediaPlayer.prepare();
    mediaPlayer.setOnPreparedListener(this);
    mediaPlayer.setOnErrorListener(this);
    mediaPlayer.setOnCompletionListener(this);
    mediaPlayer.start();
} catch (IllegalArgumentException e1) {
    e1.printStackTrace();
} catch (IllegalStateException e1) {
    e1.printStackTrace();
} catch (IOException e1) { 
    e1.printStackTrace();
}

有人知道纯音频流是否有限制吗?我使用了多种格式和不同的扩展名.

Does anyone know if there is a limitation for audio only streams? I used multiple formats and different extensions.

其他问题:有人有m3u8音频流的URL，所以我可以测试其他流吗?

Other question: does anyone have an URL of an m3u8 audio stream, so I can test other streams?

推荐答案

我目前隶属于解决这个问题的项目. 现在，我知道这并不能真正回答您的问题，只是出于洞察力，即使在Android 4.0+ M3U8上，支持充其量也充其量，而最糟的情况也很糟糕.

I'm currently attached to a project tackling this very subject. Now I know this doesn't really answer your question, but just for insight, even on Android 4.0+ M3U8 support is spotty at best, awful at worst.

例如:

• Nexus 7在Akmai上失败，可以在UStream上运行
• Droid RAZR在Akmai和UStream上均可使用.

现在缺少通过类扩展来修补库的功能(并且每个其他android次要版本都具有.so)，我们发现没有仅SDK/NDK的解决方案；经过一个月的反复试验，我们放弃了该项目(费用太高).

Now short of patching the libraries via class extension (and having .so's for every other android minor version) we found no SDK/NDK-only solution; we gave up after a month of trial and error on our project (too costly).

我们实现的解决方案是:尝试SDK MediaPlayer.如果失败了，请使用基于FFMPEG的播放器(内部开发，以危险，ffplay，android-fplayer和dolphin-player为灵感).

The solution we implemented was: Try the SDK MediaPlayer. If that fails use a FFMPEG based player (developed in-house, using dranger, ffplay, android-fplayer and dolphin-player as inspiration).
