• How do I actually use ffmpeg on Android ?

  19 décembre 2013, par slhck

  I have a very basic question regarding Android and ffmpeg. I obtained ffmpeg from http://bambuser.com/opensource and was able to compile it for ARM.

  The results are the binaries (ffmpeg) as well as several libsomething.so files.

  My question is : Is this enough to decode videos ? How do I actually use ffmpeg then ?

  To load the library I have :

  static {
  
      System.load("/data/data/com.package/lib/libavcodec.so");
  
   }

  It loads fine. But what then ?

  
  _{More explanation : I saw other projects where people had their ffmpeg source in a JNI directory in the project. They also created some Android.mk files and some C code along with it. Would I need this as well ? Why would I create the .so files first and then copy the ffmpeg source code again ?}
  

  
  _{I know the NDK and how it should work but I've never seen an example of how one would actually call ffmpeg functions using it, because people seem to be hiding their implementations (which is sort of understandable) but not even giving useful pointers or examples.}
  

  
  _{Let's just say I wanted to decode a video file. Which kind of native methods would I need to implement ? How do I run the project ? Which data types need to be passed ? etc. There are certainly a few people here who have at least done that, I know this from searching for hours and hours.}
  

• How can I download a video with url beginning with blob:https://…

  11 août 2017, par iMax

  I would like to know if it is possible to download a video from a URL beginning with blob :

  blob:https://www.xyz123…

  i would prefer a terminal solution (ffmpeg ?, youtube-dl ?). but i have not found anything on the world wide web.

  Again : I have the url of the video stream, which looks like the above. How can I download the complete video ?

  Update

  Ok. I now found a webpage which allowed me to download the video file I wanted :
  https://video-download.online/

  But I am still wondering if there is a Terminal solution for downloading video with blob-URL (like in arte mediathek [ example arte ] or in zdf mediathek [ example zdf ]).

  Does nobody know how to do it ?

• FFMPEG not converting or sending new video to folder

  7 mars 2016, par David Draw

  So recently I wanted to work on converting any video file that isn’t a MP4 file to that very file type. I did a lot of browsing and FFMPEG was the solution.
  I tried using FFMPEG_php on my wamp server but seems it is outdated and is no longer updated
  So I downloaded the static package off the FFMPEG website and put it into my C : drive and put the path to it in my computer, following some videos and tutorials online to do so.

  I believe calling it from the php file with a path is what I have to do as there is so much conflicting information on this which isn’t clear.

  So I’m on windows 7 build 7601
  I use wamp server 2.5 with the Highest PHP, MYSQL and APACHE.

  I added the below code into my php script after the file is moved to the first folder as by a few tutorials I’ve read. But the uploaded file is not converting nor is being put in the destination_mp4 folder.

  Any help would be greatly appreciated. Thank you.

     if(move_uploaded_file($file_loc,$folder.$final_file))
  
      {
  
  
  
      exec("C:/ffmpeg/bin/ffmpeg.exe  -i ".$folder.$final_file." ".   $destination_mp4."");
  
      $newName = $_SERVER['REMOTE_ADDR'].'_'.$_SESSION['id'].''.time();
  
      $mp4Name=$newName.'.mp4';
  
      $destination_mp4='C:/wamp/www/include/uploadvideomp4/'.$mp4Name;
