• Http 400 error : requesting https site with ip instead of hostname Android

  8 novembre 2016, par David Barishev

  Im am developing an android application using xamarin.android.
  In my application i use ffmpeg as a static library, from here.

  In my app i try to access a https site, but i was getting a dns error until i read the documentation, it stated that :

  A limitation of statically linking glibc is the loss of DNS
  resolution. Installing
  nscd through your package manager will fix this or you can use
  "ffmpeg -i http://<ip address="address" here="here">/"</ip> instead of "ffmpeg -i http://example.com/"

  So i tried to lookup the ip address and just replace the hostname. Here is the code i have written :

  ...
  
  //part of main program
  
  if (inputUrl.StartsWith("http"))
  
  {
  
     var splits = inputUrl.Split('/');
  
     var hostName = splits[2];
  
     var ip = GetIpForHost(hostName);
  
     splits[2] = ip;
  
     inputUrl= string.Join("/",splits);
  
  }
  
  //calling ffmpeg with the new url
  
  ...
  
  
  
  private static string GetIpForHost(string hostname)
  
  {
  
      System.Net.IPHostEntry host = System.Net.Dns.GetHostEntry(hostname);
  
      return host.AddressList.First().ToString();
  
  }

  The code works fine, but now i’m getting different error, here is the ffmpeg log :

  [https @ 0xb2b08e0] HTTP error 400 Bad Request

  The original url i tried :

  https://r8---sn-ivuoxu-ua8l.googlevideo.com/videoplayback?pl=26&itag=22&mt=1478622247&ms=au&ei=Mv0hWLWEAs-VW7zch6AB&mv=m&upn=DLluZN9oSzo&mn=sn-ivuoxu-ua8l&expire=1478644114&mm=31&ratebypass=yes&id=o-AC_NwrGbkh5OVe-ypJh2WaxzMBK5grMVsSYyG_wMQVZI&ip=5.29.246.6&pcm2cms=yes&key=yt6&lmt=1478408938763105&dur=229.575&initcwndbps=2682500&ipbits=0&gcr=il&requiressl=yes&sparams=dur,ei,gcr,id,initcwndbps,ip,ipbits,itag,lmt,mime,mm,mn,ms,mv,pcm2cms,pl,ratebypass,requiressl,source,upn,expire&mime=video/mp4&source=youtube&signature=0E47DFC7FBBDBCD6F36B56FB9871ED3B0DF4D12A.103BAB44FFEE918B78C7D076243B45AF69C444EC

  I have no problem accessing the original url through the browser, at the time i ran the program(There is a expired tag in the url,since i’m generating it at runtime).

  I speculate that it’s not possible to connect via https through ip ?
  Is there another way to connect to the url without the hostname, since android does have build in dns resolution, since i am able to view the url through the browser ?

• ffmpeg crashing on my ec2 linux

  19 décembre 2016, par Alex Bollbach

  I have a node script that has the line :

  execSync('ffmpeg -loglevel panic -i ${path} -acodec copy -f segment -segment_time 10 -vcodec copy -reset_timestamps 1 -map 0 ./tmp/%d.ts');

  Basically, I’m splitting a given video into 10 second segments. This works on my development machine where I have ffmpeg installed :

  However, when I push the code to my ec2 instance (running the linux AMI), I get this crash :

  Error: Command failed: ffmpeg -loglevel panic -i ../test11.mp4 -acodec copy -f segment -segment_time 10 -vcodec copy -reset_timestamps 1 -map 0 ./tmp/%d.ts

  I have checked that all the files and directories exist and are organized correctly in both cases. The only thing I’ve deduced is that the ffmpeg versions vary between machines, so :

  (developement-Machine)$ ffmpeg -version

  (developement-Machine)$ ffmpeg version 3.0.2 Copyright (c) 2000-2016 the FFmpeg developers

  (ec2)$ ffmpeg -version

  (ec2)$ ffmpeg version N-61041-g52a2138

  Is it the case that the ffmpeg version issues are the culprit here and if so how can I get them in sync ? Locally I simply used Homebrew to install ffmpeg. On the ec2, I’ve used YUM as a package manager to install node and npm before but it isn’t trivial to install ffmpeg. I’ve tried to wget the static builds on ffmpeg sites but after un-taring them I get a directory of directories and I’m not sure how to proceed. The original ffmpeg I installed on my ec2 was here (http://ffmpeg.gusari.org/static/64bit/ffmpeg.static.64bit.2014-02-16.tar.gz)

  Either way I am making no progress and I could spend the next 6 hours figuring out what is going on in my linux shell. So I realize this question is a bit unfocused but is the crash likely an ffmpeg version ? and if so, how can I install the local version I have of ffmpeg on my production ec2 server ?

• Mirror not found when trying to install FFMPEG on CENTOS7

  I’m on a dedicated server with Root access. not familiar with servers. Im trying to install FFMpeg on my server but following online instructions I’m getting errors can’t figure out how to solve it. So any light on this will be very appreciated.

   One of the configured repositories failed (DAG RPM Repository),
  
   and yum doesn't have enough cached data to continue. At this point the only
  
   safe thing yum can do is fail. There are a few ways to work "fix" this:
  
  
  
       1. Contact the upstream for the repository and get them to fix the problem.
  
  
  
       2. Reconfigure the baseurl/etc. for the repository, to point to a working
  
          upstream. This is most often useful if you are using a newer
  
          distribution release than is supported by the repository (and the
  
          packages for the previous distribution release still work).
  
  
  
       3. Disable the repository, so yum won't use it by default. Yum will then
  
          just ignore the repository until you permanently enable it again or use
  
          --enablerepo for temporary usage:
  
  
  
              yum-config-manager --disable dag
  
  
  
       4. Configure the failing repository to be skipped, if it is unavailable.
  
          Note that yum will try to contact the repo. when it runs most commands,
  
          so will have to try and fail each time (and thus. yum will be be much
  
          slower). If it is a very temporary problem though, this is often a nice
  
          compromise:
  
  
  
              yum-config-manager --save --setopt=dag.skip_if_unavailable=true
  
  
  
  failure: repodata/repomd.xml from dag: [Errno 256] No more mirrors to try.
