• bindProcessToNetwork is not working with ffmpeg in android

  12 janvier 2020, par Mithun Sarker Shuvro

  I am using FFmpeg to re stream video from a camera(which is connected via wifi with no internet connection) to another server, and I want to do the re streaming process via cellular data. As I am already connected to wifi and to use cellular data at the same time bindProcessToNetwork() . Before executing ffmpeg command I have done the the following

  final ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
  
  NetworkRequest.Builder req = new NetworkRequest.Builder();
  
  req.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);
  
  req.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);
  
  cm.requestNetwork(req.build(), new ConnectivityManager.NetworkCallback() {
  
      @Override
  
      public void onAvailable(Network network) {
  
          //here you can use bindProcessToNetwork
  
          //cm.getNetworkInfo(network);
  
          if (cm.getNetworkInfo(network).getType() == ConnectivityManager.TYPE_MOBILE) {
  
              cm.bindProcessToNetwork(network);
  
          }
  
      }
  
  
  
  });

  it is working fine in most of the case, like webview is working properly by using cellular data , while connected to wifi , but when I try to execute any ffmpeg command it doesn’t work .

• Streaming Kinect RGB and Depth Camera to ffserver

  25 avril 2017, par Dove Devic

  I am wanting to stream Kinect RGB and Depth camera data up to a AWS Server which is running ffserver and ffmpeg. I have the Kinect hooked up to a Windows machine, so this would preferably need to be done in .NET ; either C# or C++.

  My question :

  Its pretty trivial to gather the stream of the RGB Camera, and I don’t think it will too hard to send this up to the server, but getting the stream of the Depth Camera(the "greyscale" camera) is something I am having trouble with.

  I have looked around, and found this source on github, as well as this one, also on github, but I don’t think it is exactly what I need.

  Has anyone done this before, or knows how to even start about this ? Thanks !

  It seems that there are solutions, but not very clear ones.

• Could I use openframeworks and upd play the video in other computer ?

  7 novembre 2014, par cindywmiao

  I want to use openframework, udp connection and FFMPEG encode and decode to play the video from the other computer.

  I could not find how to turn the byte[] into one frame with FFMPEG decode. Is there some example/demo ?
  I found two demos from Internet. http://forum.openframeworks.cc/t/export-audio-and-or-video-using-ffmpeg/5123 This one is only the example for mac, but I use visual studio.

  Then, http://www.morethantechnical.com/2013/04/11/simplified-ffmpeg-video-writer-also-for-openframework-w-code/, this one does not work. It shows my the error :

  The program can't start because avcodec-56.dll is missing from your computer. 
  
  Try reinstalling the program to fix this problem.

  Could someone give me a clue how to do it ?
