• FFMPEG iOS 7 Library

  15 septembre 2017, par Destiny Dawn

  I’ve tried reading many tutorials.
  I’ve spent hours on google, and stackoverflow trying answer.
  So far I’ve read : Trying to compile the FFMPEG libraries for iPhoneOS platform with armv6 and arv7 architecture FFMPEG integration on iphone/ ipad project and https://github.com/lajos/iFrameExtractor few of the many.

  I’m trying to build this library for iOS 7/Xcode 5 compatibility but it’s not working.
  A common error I’d get is :

  Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
  
  yasm/nasm not found or too old. Use --disable-yasm for a crippled build.
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solving the problem.

  I’d also get many more once that is finished. Such as :

  rm: illegal option -- .
  
  usage: rm [-f | -i] [-dPRrvW] file ...
  
         unlink file
  
  make: *** [clean] Error 64

  I’ve mostly tried using this command to start, but it always crashes on "make clean" :

  ./configure \
  
  --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc \
  
  --as='/usr/local/bin/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' \

• Video upload size

  16 mai 2014, par Jonas m

  I’m having a hard time figuring this one out, so hopefully, some of you who has tried this before, will take the time to reply and share your knowledge.

  I’m working on a site, which after release, will be feeded in the television and other commercial places. The site asks the user to upload a video with a story, and we expect alot of people to do so.

  My problem is the whole storage/space talk. A normal, unencoded iPhone recording easily fills around 100-120 MB for a minute or two.

  I’ve tried setting up and using FFMPEG to re-encode the movies, but the problem is, that one encoding sucks up 100% of the CPU, leaving the site inaccisible for anybody else.

  Is there anything you could suggest, which would be sufficient for such a site ? The client is on a budget, so price is a consideration aswell. Best of all would be a free alternative to etc. FFMPEG, but with less CPU usage.

  My specs are as follows
  CentOs 6 on a
  1GB ram DigitalOcean cloud service with nginx + php-fpm and mysql.

  Im hoping for some cleaver folks to answer this !
  Thanks in advance.
