我一直在尝试合并(连接)两个相同高度和宽度的mp4视频,但会出现一些错误。它说输出文件没有任何流。 请帮忙。 代码如下:
/gfs\./
logcat的:
String[] arg = new String[]{
ActualVideoFile.getAbsolutePath(), path
};
String list = generateList(arg);
String[] command = new String[]{
" -f concat -i " + list + " -c:v copy " + mergedVideo.getAbsolutePath()
};
try {
ffmpeg.execute(command, new FFmpegExecuteResponseHandler() {
@Override
public void onSuccess(String message) {
Log.e("SUCCESS", message);
}
@Override
public void onProgress(String message) {
Log.e("onProgress", message);
}
@Override
public void onFailure(String message) {
Log.e("onFailure", message);
}
@Override
public void onStart() {
Log.e("onStart", "start");
}
@Override
public void onFinish() {
Log.e("FINISH", "FINISHED");
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
e.printStackTrace();
}
任何帮助将不胜感激 感谢

这是我的完整代码段。我正在为视频添加图片叠加层。为了测试,我将视频和图像保存在资源文件夹
中 File myDirectory = new File(Environment.getExternalStorageDirectory() + "/EditedVideo_2/");
File outputDirectory = new File(Environment.getExternalStorageDirectory() + "/EditedVideo_2/video" + System.currentTimeMillis() + ".mp4");
Log.d("directory path",Environment.getExternalStorageDirectory() + "/EditedVideo_2/");
if (!myDirectory.exists())
{
myDirectory.mkdirs();
}
File f = new File(Environment.getExternalStorageDirectory() + "/EditedVideo_2/sample.mp4");
if (!f.exists()) try
{
InputStream is = getAssets().open("sample.mp4");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
FileOutputStream fos = new FileOutputStream(f);
fos.write(buffer);
fos.close();
}
catch (Exception e)
{
throw new RuntimeException(e);
}
Log.d("Path = ",f.getPath());
File imageFile = new File(Environment.getExternalStorageDirectory() + "/EditedVideo_2/ic_launcher.png");
if (!imageFile.exists()) try
{
InputStream is = getAssets().open("ic_launcher.png");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
FileOutputStream fos = new FileOutputStream(imageFile);
fos.write(buffer);
fos.close();
}
catch (Exception e)
{
throw new RuntimeException(e);
}
FFmpeg ffmpeg = FFmpeg.getInstance(this);
try {
ffmpeg.loadBinary(new LoadBinaryResponseHandler()
{
@Override
public void onStart()
{
Log.d("Event ","onStart");
}
@Override
public void onFailure()
{
Log.d("Event ","onFailure");
}
@Override
public void onSuccess()
{
Log.d("Event ","onSuccess");
}
@Override
public void onFinish()
{
Log.d("Event ","onFinish");
}
});
} catch (FFmpegNotSupportedException e) {
// Handle if FFmpeg is not supported by device
}
try {
// to execute "ffmpeg -version" command you just need to pass "-version"
//String[] cmd = {"-version"};
String[] cmd = {"-i",""+f.getPath(),"-i",""+imageFile.getPath(),"-filter_complex","overlay=10:main_h-overlay_h-10",outputDirectory.getPath()};
ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler()
{
@Override
public void onStart()
{
Log.d("Event ","onStart");
}
@Override
public void onProgress(String message)
{
Log.d("Event ","onProgress - "+message);
}
@Override
public void onFailure(String message)
{
Log.d("Event ","onFailure - "+message);
}
@Override
public void onSuccess(String message)
{
Log.d("Event ","onSuccess - "+message);
}
@Override
public void onFinish()
{
Log.d("Event ","onFinish");
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// Handle if FFmpeg is already running
}

有同样的问题。原来它是命令的构建方式。
这是不正确的,因为您需要分割每个命令:
String[] command = new String[]{" -f concat -i " + list + " -c:v copy " + mergedVideo.getAbsolutePath();
Chirag您的回答是:
String[] cmd = {"-i",""+f.getPath(),"-i",""+imageFile.getPath(),"-filter_complex","overlay=10:main_h-overlay_h-10",outputDirectory.getPath()};
希望这有帮助。
