  • how to record video of selenium tests running on Xvfb ?

    3 février 2016, par user299709

    I want a video recording of my selenium tests (chromedriver running on linux server with Xvfb).

    How would you go about doing this with ffmpeg or does a library already exist ? I also would like the output to be a choppy gif (I just need to know the basics of what is happening).

  • How to use youtube-dl to record live stream in parts

    23 juillet 2021, par Vikral

    Just wondering if that's possible or not to break an m3u8 live stream recording every hour and restart the recording again.

    


    I don't want to press Ctrl-C every hour to stop the recording and restart it again to get a playable downloaded file. Instead, I want to automate this.

    


    Does anyone know if that is possible ?

    


  • ffmpeg record video from image pipe with constant framerate

    4 janvier 2023, par Michael

    I'm trying to record a lossless video with ffmpeg, feeding it image data through standard input.

    


    The process is started like this (C#) :

    


    string inputArgs = "-y -f image2pipe -pix_fmt yuyv422 -i -";
string outputArgs = "-r 20 -c:v libx264 -crf 0 -pix_fmt yuv422p -preset ultrafast C:\\temp\\out.mp4";

process = new Process
{
    StartInfo =
        {
           FileName = "ffmpeg.exe",
           Arguments = $"{inputArgs} {outputArgs}",
           UseShellExecute = false,
           CreateNoWindow = true,
           RedirectStandardInput = true
        }
};

process.Start();


    


    The above works, but I have a problem with framerate. The rate I'm feeding images to ffmpeg is different over time, but I need ffmpeg to keep output rate constant. According to ffmpeg documentation, if set like this "-r 20" it should "duplicate or drop input frames to achieve constant output frame rate fps". But it doesn't. If I feed the images to the ffmpeg too slow, I'm getting fast playing video and vice versa.

    


    Am I providing wrong arguments ? Or it's somehow has to deal with ffmpeg getting images from Standard Input ?

    


    I tried these options in the output settings block : "vsync" (setting it to 1) and "fps_mode" (setting it to cfr). "vsync" doesn't have any effect, with "fps_mode" nothing works (video not recorded at all).
