java - Android 9.0 ijkplayer setSpeed 失败

Question

当我尝试在 Android 9.0 上更改视频速度时，它不起作用。仅适用于 9.0 且仅当设置速度超过 1.0 时。我只是使用 mIjkVideoPlayer.setSpeed(1.0)。它适用于 9.0 以下的所有其他设备。ijkplayer 版本：0.8.8，这是错误日志：

在初始化 ijkMediaPlayer 时添加这一行：

ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "soundtouch", 1);
