• How to solve syntax error : unexpected end of file (building ffmpeg in andoid)

  5 mai 2015, par Mar wa

  I am following this tutorial.

  While I was executing android_build.sh with cygwin, an error message appears :

  syntax error : unexpected end of file

  How can I resolve this ?

  This is the android_build.sh :

  #!/bin/bash
  
  ######################################################
  
  # Usage:
  
  # put this script in top of FFmpeg source tree
  
  # ./build_android
  
  # It generates binary for following architectures:
  
  # ARMv6 
  
  # ARMv6+VFP 
  
  # ARMv7+VFM-�d16 (Tegra2) 
  
  # ARMv7+Neon (Cortex-A8)
  
  # Customizing:
  
  # 1. Feel free to change ./configure parameters for more features
  
  # 2. To adapt other ARM variants
  
  # set $CPU and $OPTIMIZE_CFLAGS 
  
  # call build_one

• Installing full multimedia stack on server (ffmpeg,mp4box,sox,mplayer)

  29 avril 2015, par hdezela

  I’ve had a trusty text file with all(?) the steps I need to set up a full multimedia stack on a RHEL compatible server (CentOS, AWS Linux, etc.) for a few years now. However, sometimes some things are missing and I need to revise it. I know it is not complete so I’m asking for suggestions/modifications in order to get a good - and public - list of how to install all this stuff easily.

  Ideally, I want to be able to run through the file and end up with a system that’ll take any media file and be able to convert/encode/decode/whatever with it.

  This is what I have :

  yum install mesa-libGL-devel mesa-libGLU-devel libXi-devel libXmu-devel freeglut-devel freeglut ncurses-devel
  
  cd /usr/local/src
  
  mkdir /usr/local/src/tmp

• make error in OpenCV installation on ubuntu (ffmpeg CODEC_ID_XXXX was not declared in scope)

  22 avril 2015, par Anurag Priyadarshi

  I am trying to install OpenCV following this tutorial. I am through cmake.(The configuration is given at the end.) However make shows error :make[2]: ***[modules/highgui/CMakeFiles/opencv_highgui.dir/src/cap_ffmpeg.cpp.o] Error 1
  One link pointed out reason as different version of opencv and ffmpeg, but I found a piece of code in cap_ffmpeg_impl.hpp that appears to be handling it.

  #if LIBAVCODEC_BUILD >= CALC_FFMPEG_VERSION(54,25,0)
  
  #  define CV_CODEC_ID AVCodecID
  
  #  define CV_CODEC(name) AV_##name
  
  #else
  
  #  define CV_CODEC_ID CodecID
  
  #  define CV_CODEC(name) name
  
  #endif

  Not sure if it is ok for this to be commented.

  Also, I could try installing ffmpeg seperately, but I am not sure how dependencies are handled in this installation around libav.

  Would be thankful for any help in solving this problem, as well as tips/links for OpenCV installation in general.
