  • Error Exception : You do not have ffmpeg installed on your machine when using python bar_chart_race with reticulate in rstudio

    27 septembre 2020, par Zhiqiang Wang

    I have run python bar_chart_race successfully in jupyter notebook.

    


    import bar_chart_race as bcr
bcr.bar_chart_race(df=wide_1, filename=None, title='Mortality (per million) by Country')


    


    I have ffmpeg installed on my machine.

    


    > Sys.which("ffmpeg")
                       ffmpeg 
"C:\\ffmpeg\\bin\\ffmpeg.exe" 


    


    However, when I tried the same code in rmarkdown with rstudio reticulate,

    


    import bar_chart_race as bcr
bcr.bar_chart_race(wide_1)


    


    I received the following message :

    


    Exception: You do not have ffmpeg installed on your machine. Download
                            ffmpeg from here: https://www.ffmpeg.org/download.html.

    ffmpeg works fine with R animated graph packages in rstudio, and with python bar_chart_race. I have tried to re-install ffmpeg several times. Any advice would be appreciated.

    


  • ffmpeg export without color loss

    27 décembre 2020, par ser

    I'm trying to add a watermark to a video through ffmpeg, but all the exports result in loss of color information. I would like to retain the same color information as the original video, how do I do that ?

    


    Currently, I use this code :

    


    ./ffmpeg -i input.MOV -loop 1 -i logo.png -codec:v libx264 -crf 18 -preset medium -filter_complex "


    


    I realised the only way to not lose the color information is to set -crf to 0 and -preset to veryslow, but it results in a really large file size. (2 times the size of original video, which is not effective)

    


    I also get this error when I run ffpmeg :

    


    [swscaler @ 0x117577000] deprecated pixel format used, make sure you did set range correctly


    


    See Image comparison here — the blacks on the export were not as "black" as original

    


    ffprobe -show_streams for Original File

  • c# how to correctly format an ffmpeg user input stream ?

    6 janvier 2021, par user14527374

    So I'm writing a c# application which allows a user to scale a video in pixels to a custom dimension. I am strugeling to get the user input from a textbox for the mpeg psi arguments :

    


    Here is the code :

    


     var localStoragePath = Path.Combine(Path.GetTempPath(), name);
                            var directoryPath = Path.GetDirectoryName(localStoragePath);
                            Directory.CreateDirectory(directoryPath);
                            File.WriteAllBytes(localStoragePath, bytes);
                            Progress.Text = ($"File copy successful: {File.Exists(localStoragePath)}");
                            var readBack = File.ReadAllBytes(localStoragePath);
                            Progress.Text = ($"Read file Back: {readBack.Length}, {localStoragePath}");
                            var resizedFolderPath = @"C:\upscaledvideohere";
                            Directory.CreateDirectory(resizedFolderPath);
                            var resizedFiePath = Path.Combine(resizedFolderPath, Path.GetFileName(localStoragePath));

                            var psi = new ProcessStartInfo();
                            psi.FileName = @"C:\ffmpeg-2020-12-27-git-bff6fbead8-full_build\bin\ffmpeg.exe";
                            psi.Arguments = $"-i \"{localStoragePath}\" -vf scale=" + pixelsheight.Text  "\"{resizedFiePath}\"";
                            psi.RedirectStandardOutput = false;
                            psi.RedirectStandardError = false;
                            psi.UseShellExecute = true;
                            Progress.Text = ($"Args: {psi.Arguments}");


    


    For

    


     psi.Arguments = $"-i \"{localStoragePath}\" -vf scale=" + pixelsheight.Text  "\"{resizedFiePath}\""


    


    What would be the correct way to input the text for what the user typedin the pixelsheight text box ?

    


    Thanks very much.
