• Vagrant provision fails to execute the next script without an obvious reason why

  14 juin 2016, par JakeTheSnake

  I’ve created/co-opted several bash scripts to provision my guest Ubuntu 14.04 OS ; the one giving me trouble right now is installing ffmpeg. When the script finishes, vagrant simply does nothing save for sending SSH keep-alives.

  Host OS : Windows 7 x64

  The last output before the infinitely repeating keep-alives is :

  I won’t include the other scripts for the sake of brevity. When logging into vagrant with the gui nothing seems out of the ordinary, and ffmpeg is available...but nothing else is provisioned. No RVM, no Nginx, nothing.

• ffmpeg - when cutting video, last frame is green [on hold]

  4 juillet 2016, par Mister Fresh

  In a php web app, the user can upload a video and cut it in samples. Php launches a shell command with shell_exec() to start ffmpeg and cut the video.

  It works except that the last frame shows a green splash in the cut sample.

  Server is on linux. In dev environment (mac) with latest ffmpeg, the problem cannot be reproduced.

  Command is the following :

  ffmpeg -i /var/www/user_dir/web/projects/127472/cuts/1146 -ss 00:00:45 -t 15 -vcodec libx264 -s 640x360 -strict experimental -v quiet -y /var/www/user_dir/web/projects/127472/cuts/sample1954_small.mp4

• libavutil : Always use some GCC style attributes on clang

  18 juillet 2016, par Martin Storsjö

  libavutil : Always use some GCC style attributes on clang
  Clang normally disguises as GCC (defining __GNUC__), and thus get
  
  all the normal GCC specific attributes.
  Clang can also work as a drop-in replacement for MSVC, and in these
  
  cases, it doesn’t define __GNUC__, but defines _MSC_VER instead.
  Even in these setups, it still supports the GCC style attributes,
  
  thus use them, especially where there isn’t any MSVC specific
  
  version, or where the MSVC specific version doesn’t work on clang
  
  (for DECLARE_ASM_CONST).
