• Transloadit : How can I replace audio track of a given video ?

  1er septembre 2014, par Stan Wiechers

  I am having trouble forming the steps that would replace/set the audio track of an mp4. Here is my code :

   require "open-uri"
  
   transloadit = Transloadit.new(:key => ENV['TRANSLOADIT_AUTH_KEY'],:secret => ENV['TRANSLOADIT_AUTH_SECRET'])
  
   video_encode = transloadit.step('video_encode', '/video/encode', use: ":original",ffmpeg_stack: "v2.0.0", ffmpeg: { i: "http://www.stephaniequinn.com/Music/Allegro%20from%20Duet%20in%20C%...;", map:"1:0", vcodec:"copy", acodec:"copy"}) 
  
   store = transloadit.step('store', '/s3/store', :key => ENV['S3_ACCESS_KEY'], :secret => ENV['S3_SECRET_ACCESS_KEY'], :bucket => ENV['S3_BUCKET'])
  
   assembly = transloadit.assembly(:steps => [ video_encode, store ] )
  
   response = assembly.submit! open('http://techslides.com/demos/sample-videos/small.mp4')

  I am getting this message :

   'Unable to find a suitable output format'

  Could someone tell me how parametrize ffmpeg and transloadit to set the audio track of a given mp4 ? I tried many variations without any luck.

• FFMPEG for APACHE 2.4.6 (x64), PHP 5.5 (x64), MYSQL 5.6 (x64) on WINDOWS 8 (x64) MACHINE

  FFMPEG for APACHE 2.4.6 (x64), PHP 5.5 (x64), MYSQL 5.6 (x64) on WINDOWS 8 (x64) MACHINE

  I need to install FFMPEG on my windows 8 machine running DRUPAL ZEN custom theme. Can someone tell me where I can get the right dll files for this purpose ? If I have to compile them myself, can someone please give me step by step instructions for how to do so ? I have searched endlessly for these dlls for days now and I have no instructions for creating what i need manually. I have a windows machine running minGW.

  I already tried using the FFMPEG dlls that are out there on teh internet but my PHP-APACHE installations seem to be unable to properly detect the FFMPEG libraries (i added php_ffmpeg.dll to EXT folder, and the rest of hte DLLs to the WINDOWS/SYSTEM32 folder).

  I am running the following versions of PHP and APACHE. Thank you very much in advance for any help you can offer me.

  PHP Version 5.5.1
  System Windows NT 6.2 build 9200 (Windows 8 Business Edition) AMD64
  Build Date Jul 18 2013 11:04:03
  Compiler MSVC11 (Visual C++ 2012)
  Architecture x64

  APACHE VERSION
  Server version : Apache/2.4.6 (Win64)
  Apache Lounge VC10 Server built : Jul 16 2013 11:31:50
  

• Cannot use FFmpeg in Xcode iOS Project (file .h not found)

  19 mars 2016, par BlackBox

  I followed almost step by step this guide.

  Almost because I downloaded, as a user suggested, ffmpeg ios library already built from here

  I followed from "Linking static libraries in Xcode" but I cannot import anyway the header files of ffmpeg. (So I got the .a files)

  For example

  #include "avformat.h"
  
  // or
  
  #import "libavformat/avformat.h"
  
  // or
  
  #import <libavformat></libavformat>avformat.h>

  Everything that I use does not work.

  I specify that those .a files are currently in my project directory, indeed, if I import the .a file, it doesn’t complain that it isn’t found, but when compiling, it complains about UTF-8 stuff because .a files are object libraries and cannot be imported that way.

  I put also the Header Search Paths for the project as it was suggested and the config.log file but nothing.

  Also I see libraries are missing from every project example of FFmpeg I was able to find on GitHub.

  Any ideas ?
