我试图将大量桌面捕获的图像发送到编码器(FFmpeg)stdin.

以下代码示例有效.

该CaptureScreen()功能可在5-10毫秒内提供图像.

如果我将图像保存在MemoryStream中,几乎不需要时间.

但我只能每45毫秒将1张图像保存到proc.StandardInput.BaseStream.

public void Start(string bitrate, string buffer, string fps, string rtmp, string resolution, string preset)
{

    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.RedirectStandardInput = true;
    proc.StartInfo.RedirectStandardOutput = true;

    proc.Start();
