• Cross-compiling for ffmpeg : libvpx decoder version must be >=0.9.1

  13 octobre 2016, par bot1131357

  (Note : I know the title is almost identical to this question, but its solution is only applicable if I were building on my own system. I am building for an embedded ARM device.)

  I am trying to build a cross-compile FFmpeg library to be targeted on an arm device, and the ./configure command tells me that libvpx is outdated.

  My version of libvpx is as follows :

  $ pkg-config --modversion vorbis 
  
  1.3.2

  When I run ./configure

  $ ./configure --prefix=/home/test/Dev/build-arm/ffmpeg-armhf/ --enable-cross-compile --cross-prefix=${CCPREFIX} --arch=armhf --target-os=linux --pkg-config-flags="--libs vpx --static --cflags" --enable-shared --enable-libvpx 
  
  ERROR: libvpx decoder version must be >=0.9.1
  
  
  
  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
  
  solve the problem.

  My vpx.pc file is located in /usr/share/pkgconfig. Since it’s for a different target (arm), Should I be putting this file somewhere else ? :

  # pkg-config file from libvpx v1.6.0-322-gc325fb7
  
  prefix=/home/test/Dev/build-arm/libvpx
  
  exec_prefix=${prefix}
  
  libdir=${prefix}/lib
  
  includedir=${prefix}/include
  
  
  
  Name: vpx
  
  Description: WebM Project VPx codec implementation
  
  Version: 1.6.0
  
  Requires:
  
  Conflicts:
  
  Libs: -L${libdir} -lvpx -lm
  
  Libs.private: -lm -lpthread
  
  Cflags: -I${includedir}

  In my config.log I see this :

  ERROR: libvpx decoder version must be >=0.9.1

  It looks like the include and library paths are not provided to the compiler, but I don’t know how I should go around solving that.
  I would really appreciate it if you could offer some guidance.

• concatenate mp4 videos with ffmpeg concat demuxer in android

  6 mai 2016, par Ara Badalyan

  I want to concatenate mp4 videos with ffmpeg, the problem is when I want to merge videos taken with Iphone and Android it throws problem

  " Non-monotonous DTS in output stream 0:1 ; previous : 150528, current : 139268 ; changing to 150529. This may result in incorrect timestamps in the output file."

  This is my code

  merge.txt

  file 'iphone.mp4'
  
  file 'android.mp4'

  ffmpeg command

  ffmpeg -f concat -i marge.txt -c copy -y merge.mp4

  If I can’t merge this videos how can i make them with same parameters (frame rate, bitrate...) and merge them ?

  P.S I use ffmpeg version 2.4.2 , because I can’t find android ffmpeg library higher then 2.4.2.
