• When reading a file line by line, I only get to execute ffmpeg on the first line

  12 avril 2016, par Shmuel

  I’m writing a Bash script in which I read a file line by line ( well, <(find /home/user/ -iname "*.MP4") to be exact ) , and for each line I execute ffmpeg, so I’m doing something like this :

  while read -r line; do
  
      ffmpeg -i "$line" [ MORE OPTIONS ... ]
  
  done < <(find /home/user/ -iname "*.MP4")

  Though, for some reason, only the first line is being processed successfuly.

  Any idea why my code ignores all other lines ?

• OpenCV libopencv_core.so.2.4.1 File Not Found

  14 novembre 2013, par benrules2

  I am trying to setup OpenCV v2.4.1 with FFMPEG v0.11 support on Scientific Linux SL release 5.0 (Boron), and I am running into a problem with a missing file that seems completely undocumented. The error I am getting is as follows :

  -- Install configuration: "Release"
  
  
  
  -- Up-to-date: /home/s18/s1138832/OpenCV/include/opencv/cv.h
  
  -- Up-to-date: /home/s18/s1138832/OpenCV/include/opencv/cxmisc.h
  
  -- Up-to-date: /home/s18/s1138832/OpenCV/include/opencv/cvwimage.h
  
  -- Up-to-date: /home/s18/s1138832/OpenCV/include/opencv2/opencv.hpp
  
  CMake Error at modules/core/cmake_install.cmake:63 (FILE):
  
  file INSTALL cannot find file
  
    "/home/s18/s1138832/OpenCV/lib/libopencv_core.so.2.4.1" to install.
  
  Call Stack (most recent call first):
  
    modules/cmake_install.cmake:57 (INCLUDE)
  
    cmake_install.cmake:56 (INCLUDE)

  I honestly don't know where to begin troubleshooting this at this point. I successfully installed without ffmpeg a few days ago, but now I can't even install with ffmpeg support set to off.

  The files that link to the missing library are :

  lrwxrwxrwx 1 s1138832 s18      21 Jun 17 18:26 libopencv_core.so ->    libopencv_core.so.2.4
  
  lrwxrwxrwx 1 s1138832 s18      23 Jun 17 18:26 libopencv_core.so.2.4 -> libopencv_core.so.2.4.1

  Any advice or prods in the right direction would be much appreciated. I would also be happy to provide more info on whatever interesting details I may have omitted.

  UPDATES : This website seems to have the same error, but I can't read it and translations patchy - http://www.opencv.org.cn/forum/viewtopic.php?f=1&t=15664 ( http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fwww.opencv.org.cn%2Fforum%2Fviewtopic.php%3Ff%3D1%26t%3D15664&act=url )

  libopencv_core.so.2.4.1 exists after "make", but "make install" deletes it somehow. I copied it and added it again, but it didn't change anything
