• Invalid data found when processing input using FFmpeg for extracting video thumbnail

  3 octobre 2016, par Simer

  I am using below command to extract thumbnail from

  'C:\ffmpeg\bin\ffmpeg -i '.$server_public_path.'\frontend\videos\gallery\user_'.$logged_in_user_id.'\\' .$video_name.' -ss 00:00:30.435 -vframes 2 -flags +global_header '.$server_public_path.'\frontend\videos\gallery\user_'.$logged_in_user_id.'\\thumbnails\\'.$video_name;

  where $server_public_path is absolute path of my project. Above command working fine when I used it on some other path and video.

  Below is the error I am getting :

• Failed to build opencv for conda

  4 octobre 2016, par Caenorst

  I’m on Ubuntu 16.04 64 bits, using Anaconda2.

  I’m trying to install Opencv for conda with FFMPEG support (for VideoCapture).

  I followed this tutorial : http://dhaneshr.net/2016/06/03/installing-opencv-2-4-x-with-ffmpeg-python-on-anaconda/

  changed cmake to 3.3.1 and -DWITH_FFMPEG=1 but when I execute
  $ conda build conda

  It fails at the test to import cv2

  You can find the whole log in this file : https://gist.github.com/Caenorst/e6bce629178540f30818a66e2f3a8663
