android - libvorbis-libogg-android中的本地引用表溢出(max = 512)

Question

请帮助我，我正在用我的项目中的libvorbis-libogg-android录制声音并编码为ogg。当我的录制时间超过30秒时，我的应用崩溃了，

private class AsyncEncoding implements Runnable {
@Override
public void run() {
    //Start the native encoder
    Process.setThreadPriority(Process.THREAD_PRIORITY_URGENT_AUDIO);
    int result = 0;
    switch (recordingType) {
        case WITH_BITRATE:
            result = VorbisEncoder.startEncodingWithBitrate(sampleRate, numberOfChannels, bitrate, encodeFeed);
            break;
        case WITH_QUALITY:
            result = VorbisEncoder.startEncodingWithQuality(sampleRate, numberOfChannels, quality, encodeFeed);
            break;
    }
    switch (result) {
        case EncodeFeed.SUCCESS:
            Log.d(TAG, "Encoder successfully finished");
            recordHandler.sendEmptyMessage(FINISHED_SUCCESSFULLY);
            break;
        case EncodeFeed.ERROR_INITIALIZING:
            recordHandler.sendEmptyMessage(ERROR_INITIALIZING);
            Log.e(TAG, "There was an error initializing the native encoder");
            break;
        default:
            recordHandler.sendEmptyMessage(FAILED_FOR_UNKNOWN_REASON);
            Log.e(TAG, "Encoder returned an unknown result code");
            break;
    }
}

}

和我的错误

我认为这里是我的问题，因为在此处创建表 https://github.com/vincentjames501/libvorbis-libogg-android/blob/master/jni/libvorbis-jni/org_xiph_vorbis_encoder_VorbisEncoder.c

我认为本地参考表是指JNI VM本身。在JNI内部，它维护对象的引用表，我怀疑您只是在不释放它们的情况下使用了太多的引用表。如果是别人写的代码，那应该向他们报告，这可能是一个错误。

如果您自己进行调查，请尝试阅读JNI文档，尤其要注意与全局和本地引用有关的调用，尤其是DeleteLocalRef函数。
