• FFMPEG and -crf on Android

  12 juin 2014, par mister-viper

  yesterday I managed to build a newer Version of FFMPEG for Android. I directly created a binary which allows me to invoke commands per commandline. I builded the Version using NDK r9d and the 4.8 linux_x86_x64 toolchain.

  After including everything in my Application my goal was to execute the command for which I did the whole effort.

  My goal is to run :

  ffmpeg -i example.mp4 -r 30 -vcodec libx264 -crf 0 output.mp4

  Running this command on the command line via python works absolutly fine. However, running this command on Android does not work.

  1) I get the error that I have to add

  -strict experimental

  After reading FFMPEG docu I found out, that this is due to the libx264. However, I do not understand why I have not to add this comment in the Python version.

  2) After adding the parameter above, I was able to convert the video. However, the result was horrible. The transcoded images were just some noisy blinking green stuff. Thus, I looked for the problem. The problem is the parameter :

  -crf 0

  Due to this parameter, the result was so horrible. However, if I change the parameter to

  -crf 1

  everything is working as expected. BUT : I really want a lossless encoding here. That was the reason for choosing -crf 0. Moreover, this parameter works fine in my python version.

  Can anybody explain to me :
  1) What are I’m doing wrong ?
  2) How can I use -crf 0 on Android ?

  Best regards,
  André

• Perl or Python for daemons on linux [on hold]

  17 juin 2014, par SurveillanceWizard

  I am kinda at crossroads I know HTML and PHP so I am not new to programing but I know need to pick up one more for what I want to do. I am trying to create a daemon that listens to a socket port for any kind of signal and when there is a something that comes in on that port script will execute shell ffmpeg with a mounted video feed from ffserver to stream copy to a folder or drive for storage. I "could" do this with PHP but I know I may memory leaks and other problems, so I want to know if I should learn perl or python as either one of those will definitely be able to accomplish what I want to do. this would run on a distro of linux server ( no GUI)

• Chrome times out on streaming FFMPEG output from ASP.NET Web Api

  3 août 2014, par Hayden McAfee

  I’ve got a unique problem here !

  UPDATE 2 So it turns out the development below is FALSE, the inconsistency of the bug made it seem like not closing the stream made it work... but in fact the same issue persists !

  UPDATE Interesting development ; if I comment out ffmpegBufferedIn.Close(); below, the entire stream always goes through fine... the request just never ends. What could be going on here ?

  I’m writing a web service that stores audio files in Azure Blob Storage, and converts them to MP3 live when requested through my ASP.NET Web API endpoint. I accomplish this by using ’DownloadToStream’ via the Azure Storage API, feeding that stream through the STDIN of an FFMPEG process, and sending the STDOUT stream as the request response.

  The block of code that does this looks like this :

  public HttpResponseMessage Get(Guid songid)
  
  {
  
      // This could take awhile.
  
      HttpContext.Current.Server.ScriptTimeout = 600;
  
  
  
      Process ffmpeg = new Process();
  
      ProcessStartInfo startinfo = new ProcessStartInfo(HostingEnvironment.MapPath("~/App_Data/executables/ffmpeg.exe"), "-i - -vn -ar 44100 -ac 2 -ab 192k -f mp3 - ");
  
      startinfo.RedirectStandardError = true;
  
      startinfo.RedirectStandardOutput = true;
  
      startinfo.RedirectStandardInput = true;
  
      startinfo.UseShellExecute = false;
  
      startinfo.CreateNoWindow = true;
  
      ffmpeg.StartInfo = startinfo;
  
      ffmpeg.ErrorDataReceived += ffmpeg_ErrorDataReceived;
  
  
  
      // Our response is a stream
  
      var response = Request.CreateResponse();
  
      response.StatusCode = HttpStatusCode.OK;
  
  
  
      // Retrieve storage account from connection string.
  
      CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
  
          CloudConfigurationManager.GetSetting("StorageConnectionString"));
  
  
  
      // Create the blob client.
  
      CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
  
  
  
      // Retrieve reference to a previously created container.
  
      CloudBlobContainer container = blobClient.GetContainerReference("songs");
  
  
  
      // Retrieve reference to a blob
  
      CloudBlockBlob blockBlob = container.GetBlockBlobReference(songid.ToString());
  
  
  
      ffmpeg.Start();
  
      ffmpeg.BeginErrorReadLine();
  
  
  
      // Buffer the streams
  
      var ffmpegBufferedIn = new BufferedStream(ffmpeg.StandardInput.BaseStream);
  
      var ffmpegBufferedOut = new BufferedStream(ffmpeg.StandardOutput.BaseStream);
  
  
  
      blockBlob.DownloadToStreamAsync(ffmpegBufferedIn).ContinueWith((t) => {
  
          ffmpegBufferedIn.Flush();
  
          ffmpegBufferedIn.Close();
  
      });
  
  
  
      response.Content = new StreamContent(ffmpegBufferedOut);
  
      response.Content.Headers.ContentType = new MediaTypeHeaderValue("audio/mpeg");
  
  
  
      System.Diagnostics.Debug.WriteLine("Returned response.");
  
      return response;
  
  }

  This works quite well in all browsers - all except for Chrome, which has an interesting way of buffering audio streams. Chrome will buffer the first 2 megabytes of a stream, then keep the connection open and wait until the user gets closer to playing the next segment of a file before consuming the rest of the stream. This should be fine - and for some songs it is. For others, I get this :

  

  At first I thought this was due to some kind of timeout - But it happens at a different time and size for each file. It is consistent within about 15 seconds on the same songs, however. The output on the server side is normal - no exceptions thrown, and FFMpeg finishes encoding the song successfully.

  Here’s the server-side output of the above request :
