  • Read and Save rtsp stream using FFMPEG using python with less memory size

    25 août 2022, par Vishak Raj

    I am trying to read a rtsp stream and save in a file, for that I am using the ffmpeg in python

    &#xA;

    import ffmpeg&#xA;&#xA;stream = ffmpeg.input(rtsp_link, t=10)&#xA;print(stream)&#xA;&#xA;file = stream.output("test.mp4")&#xA;testfile = file.run()#capture_stdout=True, capture_stderr=True&#xA;

    &#xA;

    but this save the video file in high space, for 10 second video, the file occupies around 3 Mb, how to reduce the file size

    &#xA;

    thanks

  • Can't save process's output stream to file

    10 octobre 2018, par Wahid Masud

    I’m using ffmpeg.exe as a process and output the converted video to memory, then from memory I’m saving the data to a video file (this is the requirement I can’t directly save the converted video to a file). But the conversion is not working for some reason, Here is what I’ve tried,

    var ffmpeg = HttpContext.Current.Server.MapPath("~/FFMpeg/ffmpeg.exe");
    
var outputDir = HttpContext.Current.Server.MapPath("~/Uploads/converted.mp4");
    
var inputDir = "https://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_10mb.mp4";
    
var args = "-i " + inputDir + " -c:v libx264 -preset veryslow -crf 26 " +
    
            "-ar 44100 -ac 2 -c:a aac -strict -2 -b:a 128k -";
    

    
var process = new Process();
    
process.StartInfo.UseShellExecute = false;
    
process.StartInfo.FileName = ffmpeg;
    
process.StartInfo.WorkingDirectory = ffmpeg.Replace("\\ffmpeg.exe", "");
    
process.StartInfo.Arguments = args;
    
process.StartInfo.RedirectStandardOutput = true;
    
process.Start();
    
process.EnableRaisingEvents = true;
    
//process.WaitForExit();
    
Stream output = process.StandardOutput.BaseStream;
    
process.Exited += (sender, e) =>
    
{
    
    using (var fileStream = File.Create(outputDir))
    
    {
    
        output.Seek(0, SeekOrigin.Begin);
    
        output.CopyTo(fileStream);
    
    }
    
};  

    The output file converted.mp4 is created but its 0 kb.
