• MobileFFMPeg Not converting mkv to Mp4

  7 mai 2020, par Jlee

  I'm currently running the following code on my device in order to convert all mkv files in a directory to an mp4. But for some reason no files are converted. I double checked the dir name and it is correct, is there something wrong with my syntax ?

  



  let path = self.documentsDir()
let url = URL(string: path.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!)
     var rc = MobileFFmpeg.execute("-i jellyfish.mkv -c:v libx264 -preset -slow -crf 22 -c:a copy youroutput.mp4")
          if (rc == RETURN_CODE_SUCCESS) {
               print("Command execution completed successfully.\n");
                } 
          else if (rc == RETURN_CODE_CANCEL) {
                print("Command execution cancelled by user.\n");
                } 
           else {
                print("Command execution failed with rc=%d and output=%@.\n", rc, MobileFFmpegConfig.getLastCommandOutput);
                }

• 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.
