  Before it was that there was no ffmpeg buildpack on heroku, I added it with
https://elements.heroku.com/buildpacks/jonathanong/heroku-buildpack-ffmpeg-latest

  


  But now I just get state changed and see no errors. Any help would be greatly appreciated !

  


• FFMPEG : Add timestamp to file name HLS

  7 mai 2020, par Neel Dutta

  I want to add timestamp to my file name in the following ffmpeg command (in nginx rtmp) :

  



  exec ffmpeg -i rtmp://localhost:1936/stream/$name 
                -c:v libx264 -b:v 2500k -g 30 -r 30 -s 1280x720 -vf "drawtext=fontfile=/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-Bold.ttf: text=%{localtime}: fontsize=30: fontcolor=white@0.8: x=10: y=h-th-10" -preset fast -profile:v baseline -hls_list_size 0 -f hls /network_drive/$name-$date_%d-%b-%y-%H-%M-%S.m3u8
                -ss 00:00:05.000 -vframes 1 /network_drive/$name.jpg;


  



  What i want to achieve is the an .m3u8 file, with a filename of e.g : "stream_name-01-Apr-2020-10-46-45.m3u8", followed by its .ts files e.g : "stream_name-01-Apr-2020-10-46-450.ts, stream_name-01-Apr-2020-10-46-451.ts, stream_name-01-Apr-2020-10-46-452.ts", and so on.

  



  But the above command doesnt seem to work, and results in filename "stream_name-%d-%b-%y-%H-%M-%S.m3u8".
I've tried using strftime, but had no luck.

  


• How to automaitcally install ffmepg in c#

  25 janvier 2021, par user14527374

  so I am writing a c# application which uses ffmpeg to upscale videos. Currently, it checks if ffmpeg is installed, and if not, prompts the user to install it.

  


  {
        if (File.Exists(@"C:\ffmpeg-2020-12-27-git-bff6fbead8-full_build\bin\ffmpeg.exe"))
        {
            
        MessageBox.Show("Please note that this will only upsalce a video, it will not remaster it. Program C 2020 Keifmeister Technologies. Aka this will clear up the image but not upgrade character models or anything. Cheers.");
    }
    else
    {
        MessageBox.Show("You need to have ffmpeg installed, and you do not. Opening download link, please extract the downloaded zip file to root of yout c:\\ drive. Thanks.");
        Process.Start("https://github.com/GyanD/codexffmpeg/releases/download/2020-12-27-git-bff6fbead8/ffmpeg-2020-12-27-git-bff6fbead8-full_build.zip");
    }
}


  


  I am wondering, is there instead a way to install ffmpeg automatically and print its install location as a string ? Thanks very much.
