如何使用javacv在android中将图像转换为视频?

我尝试使用这个类，package com.example.ndkfoo_sample;导入静态 com.googlecode.javacv.cpp.opencv_core.cvReleaseImage;导入静态 com.googlecode.javacv.cpp.opencv_highgui.cvLoadImage;导入静态 com.googlecode.javacv.cpp.opencv_highgui.cvShowImage;导入静态 com.googlecode.javacv.cpp.opencv_highgui.cvWaitKey；导入静态 com.googlecode.javacv.cpp.opencv_imgproc.CV_GAUSSIAN;导入静态 com.googlecode.javacv.cpp.opencv_imgproc.cvSmooth；导入 com.googlecode.javacv.cpp.opencv_core.IplImage;导入 android.os.Bundle;导入 android.app.Activity;导入 android.view.Menu;公共类 MainActivity 扩展 Activity {//@覆盖public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);IplImage img=cvLoadImage("helloworld.jpg");cvShowImage("/mnt/sdcard/helloworld",img);cvSmooth(img,img,CV_GAUSSIAN,13);cvShowImage("模糊图像",img);cvWaitKey();cvReleaseImage(img);}@覆盖公共布尔 onCreateOptionsMenu(菜单菜单){getMenuInflater().inflate(R.menu.activity_main, menu);返回真；}}我的错误就像， opencv 错误未指定的错误.我的问题是如何在android中集成opencv/javacv.有什么步骤或教程吗?谢谢， 解决方案 使用以下几行.**opencv_core.IplImage img = cvLoadImage("/sdcard/folder/img1.jpg");FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("/sdcard/folder/test.mpeg",200,150);尝试 {recorder.setCodecID(CODEC_ID_MPEG1VIDEO);recorder.setFrameRate(30);recorder.setPixelFormat(PIX_FMT_YUV420P);录音机开始()；for (int i=0;i**这是由 javacv 库支持的.有关更多详细信息，请阅读 Javacv Readme.txt 文件.希望这会帮助你.i want to convert the sdcard images into video in android.After many of searching i found it is possible in javacv.when i try simple javacv sample in pure java,its working perfectly in my eclipse.but when i turn into android,the same sample does not run in android.i download and add all the .jar files and .so files in myproject->libs/armeabi folder.my project doesn't show any errors.but error occcured during the runtime.i try with this class,package com.example.ndkfoo_sample;import static com.googlecode.javacv.cpp.opencv_core.cvReleaseImage;import static com.googlecode.javacv.cpp.opencv_highgui.cvLoadImage;import static com.googlecode.javacv.cpp.opencv_highgui.cvShowImage;import static com.googlecode.javacv.cpp.opencv_highgui.cvWaitKey;import static com.googlecode.javacv.cpp.opencv_imgproc.CV_GAUSSIAN;import static com.googlecode.javacv.cpp.opencv_imgproc.cvSmooth;import com.googlecode.javacv.cpp.opencv_core.IplImage;import android.os.Bundle;import android.app.Activity;import android.view.Menu;public class MainActivity extends Activity {// @Overridepublic void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);IplImage img=cvLoadImage("helloworld.jpg"); cvShowImage("/mnt/sdcard/helloworld",img); cvSmooth(img,img,CV_GAUSSIAN,13); cvShowImage("Blur-Image",img); cvWaitKey(); cvReleaseImage(img);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true;}}My error is like as, opencv error unspecified error.My question is how to integrate opencv/javacv in android.is there any steps or tutorials.?thanks, 解决方案 Use the following lines .**opencv_core.IplImage img = cvLoadImage("/sdcard/folder/img1.jpg");FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("/sdcard/folder/test.mpeg",200,150); try { recorder.setCodecID( CODEC_ID_MPEG1VIDEO); recorder.setFrameRate(30); recorder.setPixelFormat( PIX_FMT_YUV420P); recorder.start(); for (int i=0;i<100;i++) { recorder.record(image[x]); } recorder.stop(); } catch (Exception e){ e.printStackTrace(); }**This is supported by javacv library. for more details read Javacv Readme.txt file.
