音频播放在Chrome 64上暂停/停止 [英] Audio playback halts/stops on Chrome 64

问题描述

Google刚刚改变了Chrome预装音频和视频的方式;请参阅：

更新3：

此问题已在Chrome 65中修复。

不起作用

mp3wrap

mp3wrap output.mp3 *。 mp3
输出文件仍然损坏并暂停

ffmpeg

ffmpeg -iconcat：0.mp3 | 1.mp3-acodec copy output.mp3
输出文件仍然损坏并暂停

做工

mp3val带-f参数

简单地连接/ implode你的音频二进制文件（在PHP中，我做了 implode（''，$ audioBinaries），然后运行 mp3val -f concatenated-audio-file.mp3 。 -f 参数非常重要，它意味着尝试修复错误。

如何安装在MacOS上： brew install mp3val
在Deb / Ubu上：

code> apt-get install mp3val

Google just changed how Chrome preloads audio and video; see: https://googlechrome.github.io/samples/media/preload-metadata

It's my understanding that simply setting preload attribute to auto should fix the problem, however, I have been unable to do so:

• https://jsfiddle.net/NinoSkopac/f4zscrdy/1/

let mp3 = 'https://s3-staging.read2me.online/audio/5a745d88483d86.76121223.mp3';
let audio = new Audio(mp3);
audio.preload = 'auto';

audio.play();

• https://jsfiddle.net/NinoSkopac/rst8aspm/

<audio src="https://s3-staging.read2me.online/audio/5a745d88483d86.76121223.mp3" preload="auto" autoplay></audio>

Both of these will stop playing within a minute on Chrome 64 and Chrome 65-dev (other browsers and older Chromes are unaffected). I have replicated this issue on Mac, Windows and Android.

During my debug process, I have attached all possible media events to the JS object (i.e. audio.addEventListener('timeupdate', () => { console.log('timeupdate') })) and at first the events were firing like this:

progress timeupdate progress timeupdate [...]

Later like this: timeupdate timeupdate timeupdate [...]

When the audio playback stopped, I got a handful of error events, and dumping audio.error returns: PIPELINE_ERROR_DECODE: Failed to send audio packet for decoding: timestamp=81763265 duration=26122 size=201 side_data_size=0 is_key_frame=1 encrypted=0 discard_padding (ms)=(0, 0)

How do I fix this? Is this a Chrome bug?

UPDATE:

• OGG plays fine: https://jsfiddle.net/NinoSkopac/2hktqcqt/1/
• This does seem to be a Chrome bug: https://bugs.chromium.org/p/chromium/issues/detail?id=794782
• A similar error on Github: https://github.com/video-dev/hls.js/issues/1529

UPDATE 2:

chrome://media-internals/ reveals this:

UPDATE 3:

This issue has been fixed in Chrome 65.

解决方案

After a couple of days of trial and error and research, I have confirmed what doesn't and does work.

Doesn't work

mp3wrap

mp3wrap output.mp3 *.mp3 the output file is still corrupted and halts

ffmpeg

ffmpeg -i "concat:0.mp3|1.mp3" -acodec copy output.mp3 the output file is still corrupted and halts

Does work

mp3val with -f argument

Simply concatenate/implode your audio binaries (in PHP I do implode('', $audioBinaries) and then run mp3val -f concatenated-audio-file.mp3. The -f argument is essential and it means "try to fix errors".

How to install mp3val?

On MacOS: brew install mp3val On Deb/Ubu: apt-get install mp3val
