• 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 .

• Removing GRUB

  14 avril 2011, par Multimedia Mike — General

  I have a Windows/Linux dual-booting computer that I don’t want to be dual boot anymore— the Linux part needs to go. Thus, the GRUB bootloader needs to be removed so that Windows boots normally. I found lots of tips around the internet about how to do this. Of course, none of them worked. So I must add to the general body of knowledge.

  I found tips that described how to manually remove GRUB via Linux— by using 'dd' to overwrite no more than 446 sectors of the boot disk with zeros. This strikes me as a dangerous and unstable proposition. It also wasn’t an option since I had already opted to reformat the formerly Linux partition via the Windows CD-ROM before I endeavored to remove the bootloader.

  Other forums and sites mentioned a combination of utilities found on the Windows CD-ROM including FIXBOOT, FIXMBR, and BOOTCFG. While these programs performed some functions, they didn’t achieve the desired effect— to make Windows boot automatically.

  New idea : Repartition the disk such that there is a (relatively) tiny extra partition. Then, well... reinstall Linux. I used a 4 GB partition and Ubuntu 10.10 and let it run its course which ended with installing GRUB... again.

  Seems roundabout— installing Linux specifically to boot into Windows. But it works.
