• Video Streaming shows not working in Micorsoft Edge

  22 novembre 2018, par Ragesh S

  I am newbi in using Video streaming in ASP.Net MVC project. I have a video library webpplication, most of the videos are .mp4 format. Please see my code below.

  Code

  public HttpResponseMessage Get(string filename)
  
      {
  
          var filePath = new FileStreameHelpers().GetFilePath(filename);
  
          if (!File.Exists(filePath))
  
              return new HttpResponseMessage(HttpStatusCode.NotFound);
  
  
  
          var response = Request.CreateResponse();
  
          response.Headers.AcceptRanges.Add("bytes");
  
  
  
          var streamer = new FileStreameHelpers();
  
          streamer.FileInfo = new FileInfo(filePath);
  
          response.Content = new PushStreamContent(streamer.WriteToStream, new FileStreameHelpers().GetMimeType(Path.GetExtension(filePath)));
  
  
  
          RangeHeaderValue rangeHeader = Request.Headers.Range;
  
          if (rangeHeader != null)
  
          {
  
              long totalLength = streamer.FileInfo.Length;
  
              var range = rangeHeader.Ranges.First();
  
              streamer.Start = range.From ?? 0;
  
              streamer.End = range.To ?? totalLength - 1;
  
  
  
              response.Content.Headers.ContentLength = streamer.End - streamer.Start + 1;
  
              response.Content.Headers.ContentRange = new ContentRangeHeaderValue(streamer.Start, streamer.End,
  
                  totalLength);
  
              response.StatusCode = HttpStatusCode.PartialContent;
  
          }
  
          else
  
          {
  
              response.StatusCode = HttpStatusCode.OK;
  
          }
  
  
  
          return response;
  
      }
  
    public async Task WriteToStream(Stream outputStream, HttpContent content, TransportContext context)
  
      {
  
          try
  
          {
  
              var buffer = new byte[6553600];
  
              using (var video = FileInfo.OpenRead())
  
              {
  
                  if (End == -1)
  
                  {
  
                      End = video.Length;
  
                  }
  
                  var position = Start;
  
                  var bytesLeft = End - Start + 1;
  
                  video.Position = Start;
  
                  while (position <= End)
  
                  {
  
                      var bytesRead = video.Read(buffer, 0, (int)Math.Min(bytesLeft, buffer.Length));
  
                      await outputStream.WriteAsync(buffer, 0, bytesRead);
  
                      position += bytesRead;
  
                      bytesLeft = End - position + 1;
  
                  }
  
              }
  
          }
  
          catch (Exception ex)
  
          {
  
              // fail silently
  
              Utilities.SaveException("FileStreameHelpers - WriteToStream", ex);
  
          }
  
          finally
  
          {
  
              outputStream.Close();
  
          }
  
      }

  it works fine in Firefox and Chrome but it shows error in Microsoft Edge browser like below.

  HTML

  <video width="320" height="240" controls="controls">
  
      <source src="/api/Media/Get?filename=SampleVideo_1280x720_1mb.mp4" type="video/mp4">
  
      Your browser does not support the video tag.
  
  </source></video>

  The remote host closed the connection. The error code is 0x800703E3.

  Please advice.

• ffmpeg stream encoding out produce a stream shows different program on each start

  15 octobre 2018, par Ryan Philip

  I am using ffmpeg for almost one year, my stream recently started behaving badly.

  The lines on ffmpeg screen started running crazy fast when restreaming it, causing more CPU (with no encoding). I have mapped the stream to select only one stream. But the problem is even with mapping I am getting different program each time when it is played.

  Also each program it is playing for less than a minute. There is no specific error message showing on ffmpeg screen. Only the output is behaving badly.

  I even tried ffmpeg version 3.3, 3.4 and 4.0 with same results.

  It has so many resolution streams, so i selected only 33 (video) and 34 (audio), the ones with highest resolution.

  ffmpeg -i "http://insourceip/stream.m3u8" -err_detect explode  -c copy -map 0:33? -map 0:34?  -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 out/music.m3u8

  Please help me with this.

  Below is the output : the one after (No longer receiving playlist 8) start running crazy when started.

• FFMpeg How to extract individual audio channels from wav/.w64 and insert in .mxf with track tags

  11 septembre 2018, par Vince

  Hi my problem is I have 2 .w64 files (extended wav format) each file has 16 mono channels of audio. I want to be able to extract specific channels of audio from each of those .w64 files and insert those channels into an .mxf file as separate single channel mono audio streams and to be additionally able to set the Tag information on those audio streams. I have tried using -map and so on but it seems to take all the channels from the .w64 files and insert a single audio stream of 16 channels. I apologise in advance as I’m very new to ffmpeg and thanks in advance for any advice any of you can offer. This is all specific to command line usage on windows.
  All the best

  ffmpeg -i "D :\Media\AUDIO_0.W64" -i "D :\media\NO_AUDIO.mxf" -c copy -map 0:0:0 -map 0:0:1 -map 0:0:2 -acodec pcm_s24le -map 1:0 "D :\media\out.mxf"
