android - JavaCV 从图像崩溃生成视频

Question

我从昨天开始用 android 做 javacv，在使用 FFmpegFrameRecorder 或 FrameRecorder 从图像 (IplImage) 生成视频时出错，同时在使用 cvCvtColor 的图像过滤中获得成功 和 cvCvtColor。

如图所示，灰度和翻转滤镜是通过点击第二个按钮(应用效果)完成的。

但是当点击(制作视频)时它崩溃了。

这是我从图像制作视频的代码。

String path = Environment.getExternalStorageDirectory().getPath() + "/test.mp4";
Log.i("path", path);
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(path, 256, 256);
try {

    recorder.setVideoCodec(avcodec.AV_CODEC_ID_MPEG4);
    // recorder.setCodecID(avcodec.AV_CODEC_ID_H263);
    recorder.setFormat("mp4");
    recorder.setPixelFormat(avutil.AV_PIX_FMT_YUV420P);
    recorder.start();
    for (int i = 0; i < 10; i++) {

        recorder.record(image);
    }
    recorder.stop();
} catch (Exception e) {

    e.printStackTrace();
}

image 是 IplImage 类型

在创建记录器 对象时出错。

最后，我将带有 jniLibs 的 build.gradle 放在左侧。

没有其他问题的答案。自过去 24 小时以来一直停滞不前。 :(

任何帮助都会很棒。

Answer 1

正如这篇文章中所讨论的 https://groups.google.com/forum/#!topic/javacv/Q_jxavoWdZE

我终于通过添加解决了

Loader.load(swresample.class);

在创建 FFmpegFrameRecorder 对象之前。谢谢。
