Android MediaMuxer illegalstateexception 无法停止 muxer mMediaMuxer.stop()

Question

我在停止 MediaMuxer 时遇到问题。

很多人都关注了 fadden's example一直以来，除了我使用的是音频，所以我还不能 100% 确定音频和视频轨道是否对齐。这可能是问题所在。

当我为 mMediaMuxer.stop() 设置断点时，出现 fatal error :

当我调用停止时，我可以深入到足以告诉 MediaMuxer.mState = MUXER_STATE_INITIALIZED。但它在 nativeStart(mNativeObject) 中失败了......

if (mState == MUXER_STATE_INITIALIZED) {
    nativeStart(mNativeObject);
    mState = MUXER_STATE_STARTED;

我得到了完全相同的异常，对我来说问题是，我忘记在一个线程中启动整个测试用例。
