我正在尝试制作一个实时流媒体应用程序，并且我已按照以下链接将 javacv 添加到我的项目 https://github.com/bytedeco/javacv中。我在我的应用程序（app->src->main）中创建了 jniLibs 文件夹，但我的应用程序崩溃而没有任何错误。当我尝试调试时，我发现代码在 FFmpegFrameRecorder.class 的这一行中断
public static void tryLoad() throws Exception {
if(loadingException != null) {
throw loadingException;
} else {
try {
Loader.load(avutil.class); // exception here
Loader.load(swresample.class);
Loader.load(avcodec.class);
Loader.load(avformat.class);
Loader.load(swscale.class);
avformat.av_register_all();
avformat.avformat_network_init();
} catch (Throwable var1) {
if(var1 instanceof Exception) {
throw loadingException = (Exception)var1;
} else {
throw loadingException = new Exception("Failed to load " + FFmpegFrameRecorder.class, var1);
}
}
}
}
我不知道如何解决这个错误。请帮我解决这个问题。提前致谢
编辑这是堆栈跟踪：
