• support auto birate based on internet speed using nginx-vod-module

  30 juillet 2020, par Maurya Shubham

  Allow multiple resolution video streaming from single video url - It's possible with nginx-vod-module package or I need to create different-different resolution file and set them ?

  


  Currently I've manually crated master.m3u8 file.

  


  


  #EXTM3U

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=2149280,RESOLUTION=1280x720 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=2149280,RESOLUTION=1280x720,URI="iframes-v1-a1.m3u8"

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=246440,RESOLUTION=320x184 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=246440,RESOLUTION=320x184,URI="iframes-v1-a1.m3u8"

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=460560,RESOLUTION=512x288 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=460560,RESOLUTION=512x288,URI="iframes-v1-a1.m3u8"

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=836280,RESOLUTION=848x480 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=836280,RESOLUTION=848x480,URI="iframes-v1-a1.m3u8"

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=6221600,RESOLUTION=1920x1080 index-v1-a1.m3u8

  


  #EXT-X-I-FRAME-STREAM-INF:BANDWIDTH=6221600,RESOLUTION=1920x1080,URI="iframes-v1-a1.m3u8"

  


  


  but when I crul video url the master.m3u8 file contain only one resolution.

  


  


  #EXTM3U

  


  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=4742713,RESOLUTION=1920x1080,FRAMERATE=30.000,CODECS="avc1.640028,mp4a.40.2",VIDEO-RANGE=SDR

• Getting error while deploying application with node-media-serve module and ffmpeg buildpack in heroku

  16 septembre 2020, par Anurag Gautam

  I have created a MERN app with video streaming by using node-media-serve module, with following configuration

  


  trans: {
  ffmpeg: '/vendor/ffmpeg',
   tasks: [] ,
   .....
}


  


  In local I have installed ffmpeg in trans.ffmpeg. and its working fine, But how we need to install ffmpeg in heroku .

  


  I have tried by adding heroku buildpacks
heroku buildpacks:add https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git but its showing me error. May be some issue with config only.

  


  Heroku error :
2020-09-16T11:23:54.292896+00:00 app[web.1]: 9/16/2020 11:23:54 23 [ERROR] Node Media Trans Server startup failed. ffmpeg:/vendor/ffmpeg cannot be executed.

  


  Guys can you please help me reslove this issue

  


• Could not load file or assembly 'Accord.Video.FFMPEG.x64.DLL' or one of its dependencies. The specified module could not be found

  24 septembre 2020, par Sandeep Kumar

  Trying to merge image and audio file to create a video file.

  


  I have tried

  


  

  • changing the arch (x86 and x64).

  


  • Manually moved all the dependent .dlls for "Accord.Video.FFMPEG.x64.DLL" to the the bin.

  


  • used both Accord and Aforge, both of them have the same issue.

  


  • installed VC++ redistribuable 2013 and 2015-19

  


  


  Following is the base code :

  


  private const string _basePath = @"D:\R&D Projects\AudioVideoConvertor\VideoAudioMerger\VideoAudioMerger\Images\";

    protected void Page_Load(object sender, EventArgs e)
    {
        int width = 2500;
        int height = 2100;
        int frameRate = 10;// Shuld be fix
        using (var videoWriter = new VideoFileWriter())
        {
            // default frame size 340, 220
            videoWriter.Open(_basePath + "test.avi", width, height, frameRate, VideoCodec.WMV1);
            ResizeNearestNeighbor filter = new ResizeNearestNeighbor(width, height);
            var images = Directory.GetFiles(_basePath, "*.jpg");
            var tfile = TagLib.File.Create(_basePath + "audio.mp3");
            //string title = tfile.Tag.Title;
            TimeSpan duration = tfile.Properties.Duration;
            decimal timeinSecond = Math.Round((Convert.ToDecimal(duration.TotalSeconds) * frameRate) / images.Length);
            foreach (string img in images)
            {

                using (Bitmap image = Bitmap.FromFile(img) as Bitmap)
                {
                    //As per audio length rotate image in video frame.
                    for (int i = 0; i < timeinSecond; i++)
                    {
                        videoWriter.WriteVideoFrame(filter.Apply(image));
                    }
                }
            }
            videoWriter.Close();
            MergeAudioAndVideo();
        }
    }

    private static void MergeAudioAndVideo()
    {

        File.Delete(_basePath + "mergedvideo.avi");
        Process pss = new Process();
        ProcessStartInfo si = new ProcessStartInfo();
        si.FileName = @"D:\R&D Projects\AudioVideoConvertor\VideoAudioMerger\VideoAudioMerger\ffmpeg-win64-static\bin\ffmpeg.exe";
        si.UseShellExecute = false;
        si.CreateNoWindow = true;
        si.Arguments = "-i \"" + _basePath + "test.avi\" -i \"" + _basePath + "audio.mp3\" -c:v copy -c:a copy -map 0:v:0 -map 1:a:0 \"" + _basePath + "mergevideo1" + ".avi\"";
        pss.StartInfo = si;
        pss.Start();
        pss.WaitForExit();
        File.Delete(_basePath + "test.avi");
    }
