• How to solve libx264 not found when building ffmpeg-with-libx264-enabled for android ?

  6 mars 2012, par newentry

  i am trying build android-ffmpeg-x264 downloaded from git. Link https://github.com/halfninja/android-ffmpeg-x264

  After running ./config_make_everything.sh i am getting following error

  ERROR : libx264 not found

  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
  solving the problem.

  1.I am using fedora to build both ffmpeg and x264
  2.NDK r7

  Any solution to successfully build the code ?

• Appending audio files on android 4.0

  21 mars 2012, par Ravinder

  i appended a audio file with another one (RAW_AMR output format), its working fine to Android 2.3.4 and below but it seems useless for Android 4.0. Any one have any idea how to do that.

• Live Stream Android Screen

  27 janvier 2012, par salamis

  I would like to stream Android Screen using FFMPEG and MonkeyRunners(MonkeyImage)

  I found a good Tutorial for streaming your webcam using FFMPEG and video4linux2.

  Is it possible to send the bytes from the Monkeyrunner.MonkeyImage to the FFMPEG to be converted to a live video stream ?

  Actual code :

  $ffmpeg -f video4linux2 -i /dev/video0 http://78.47.18.19:8090/cam1.ffm

  Replace it with something similar to :

  $ffmpeg -f video4linux2 -i <add here="here" python="python" stream="stream"> http://78.47.18.19:8090/cam1.ffm
  
  </add>

  Any suggestions ?
