JavaCV从图像Crashes生成视频

时间：2014-11-28 06:44:06

标签： android video ffmpeg javacv

我从昨天开始使用android进行javacv并在使用 FFmpegFrameRecorder 或 FrameRecorder 从图像（IplImage）生成视频时出错，同时使用 cvCvtColor在图像过滤中取得成功和 cvCvtColor 。

grayscale

如图所示，点击第二个按钮（应用效果）即可完成灰度和翻转过滤。

但是点击（制作视频）时会崩溃。

以下是我从图片制作视频的代码。

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();
}

图片属于IplImage

记录器对象创建时出错。

最后，我将 build.gradle 与 jniLibs 放在左侧。

其他问题的答案没有运气。自去年24小时起被困住了。 ：（

任何帮助都会很棒。

1 个答案:

答案 0 :(得分：2)

正如本文https://groups.google.com/forum/#!topic/javacv/Q_jxavoWdZE

中所述

我终于通过添加

解决了这个问题 
Loader.load(swresample.class);

在创建FFmpegFrameRecorder对象之前。 谢谢。
