我正在尝试构建一个可以处理磁盘视频的应用。 JavaCV库提供了抓取帧所需的工具。出于某种原因，我的程序在调用FrameGrabber.start（）时崩溃。
我不确定我做错了什么，我是新的Android编程。我搜索过类似的案例。 Haven没有在网上发布一个与我相似的内容。
非常感谢任何帮助。
这是我实施的代码。
package test.trackerproto;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import com.googlecode.javacv.FFmpegFrameGrabber;
import com.googlecode.javacv.Frame;
public class Saved_process extends ActionBarActivity {
String FilePath;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ffile);
// VideoView display = (VideoView)findViewById(R.id.videoView1);
Intent intent = getIntent();
FilePath = intent.getStringExtra("path");
FFmpegFrameGrabber vidcap;
// display.setVideoPath(FilePath);
vidcap = new FFmpegFrameGrabber(this.FilePath);
Log.i(camera.TAG, "Framegrab initiated");
Frame cur_frame = null;
try
{
vidcap.setFormat("mp4");
Log.i(camera.TAG, "Frame set");
vidcap.start();
} catch (com.googlecode.javacv.FrameGrabber.Exception e)
{
Log.e(camera.TAG, "Failed to start grabber" + e);
}
do
{
try
{
cur_frame = vidcap.grabFrame();
if(cur_frame != null){
Log.i(camera.TAG, "grab success");
}
} catch (com.googlecode.javacv.FrameGrabber.Exception e)
{
Log.e(camera.TAG, "video grabFrame failed: "+ e);
}
}while(cur_frame != null);
try
{
vidcap.stop();
}catch (com.googlecode.javacv.FrameGrabber.Exception e)
{
Log.e(camera.TAG, "failed to stop video grabber", e);
return;
}
}
}
我没有编译错误，当调用start（）时失败，因为最后一个log.i是＆＃34;框架集＆＃34;

答案 0 :(得分：0)
我解决了这个问题。使用的javacv版本是0.7，这个版本有类似的问题（根据我的理解，大多数版本低于0.10都有类似的问题）。截至发布日期的最新版本为0.11，使用它解决了我的问题。我把它留在这里，以防它有助于某人！
