Crash in AudioEnginePlayer

[UnknownCoder807]

Since the recent commits (I don't know when exactly) I am seeing a vast increase in crashes with AudioEnginePlayer.swift

是否有日志呢？看下音频格式的信息。

[UnknownCoder807]

I have no further logs. This is the only info I have. Its causing hundreds of crashes per day, and is only because of a recent commit.

这个没有日志很难找到原因，但是按照这个crash来看。应该是传入的音频格式不合法导致的。可以多找一些不规范的视频来播放下。看能不能重现。这个是tvos吗？还是iOS系统呢？

[UnknownCoder807]

It is both iOS and tvOS. I don't know what type of video they are viewing, the people are anonymous and unless they contact me, I don't know how to get one of the url's.

Is AudioUnitPlayer safe to use now? Are there any negatives to using it over AudioEnginePlayer ?

[kingslay]

AudioUnitPlayer 只有暂停，静音，倍数播放的能力。没有调节音效的能力。是可以安全使用的。

What do you mean by sound effects?

+1 on this.
Suddenly this crash resurfaced, and it's the most happening crash. It was fixed versions ago:
