将传入的图像流保存到视频 [英] saving incoming image stream to video

问题描述

我需要将传入的图像流保存到视频中。目前我正在图像元素上显示一系列传入图像。这就是我所拥有的：

I need to save an incoming image stream into a video. Currently I am displaying a series of incoming images on an image element. This is what I have:

private void Received(ReceivedEventArgs e)
        {
           using (MemoryStream stream = new MemoryStream(
                        e.ReceivedBytes, e.StartIndex, e.BytesTransferred))
                    {
                            JpegBitmapDecoder decoder = new JpegBitmapDecoder(stream,
                                BitmapCreateOptions.PreservePixelFormat,           BitmapCacheOption.OnLoad);
                            Videoframe = decoder.Frames[0];
                         //anyway that I can save it to a video on local disk directly??
                    }
       }

我想要知道的是，如果可以将图像流作为视频保存到硬盘上吗？如果是这样，我该怎么办呢？我用google搜索了很多，但他们都谈到了使用ffmpeg等将一系列预先存储的图像序列转换为视频;没有我觉得有帮助。任何指针/代码片段都会非常受欢迎，因为我不是编程专家。

谢谢！

What I want is to know is that if it is possible to save the image stream to the hard disk as a video? If so, how would I go about it? I have googled much but all of them talk about converting series of pre-stored image sequence to video using ffmpeg or such; none I found helpful. Any pointer/code snippet would be much appreciated since I am not an expert in programming.
Thank you!

我想解决它。这是代码：

Hi,
I manged to solve it. Here''s the code:

private Bitmap bmp;
private AviManager aviManager;
private VideoStream avistream;
private bool videocaptureactivated = false;
private Bitmap bitmap;

private void Savevideo()
{
   string strpath = Environment.GetFolderPath (System.Environment.SpecialFolder.DesktopDirectory);
   string filename = string.Format("Video Capture.avi");
   string path = System.IO.Path.Combine(strpath, filename);
   aviManager = new AviManager(path, false); 
   bmp = (Bitmap)System.Drawing.Image.FromFile(@"C:\samplescreen.bmp");
   avistream = aviManager.AddVideoStream(false, framerate, bmp);
   videocaptureactivated = true;
}

private void Received(ReceivedEventArgs e)
{
   using (MemoryStream stream = new MemoryStream(
                        e.ReceivedBytes, e.StartIndex, e.BytesTransferred))
          {
            if (videocaptureactivated)
               {
                  bitmap = (Bitmap)Bitmap.FromStream(stream);
                  avistream.AddFrame(bitmap);
               }
          }
}

private void stopsave()
{
   videocaptureactivated = false;
   bitmap.Dispose();
   aviManager.Close();
}

由于视频编译为bmp''且未压缩，因此大小很大。我的下一步是做压缩写作。



感谢Ibrahim的建议！

Since the video is compiled bmp'' and uncompressed, the size is huge. Next step for me is to do the compressd writing.

Thanks for the suggestion Ibrahim!
