• Android FFmpeg reports "file protocol not found"

  27 avril 2017, par Abdul Mateen

  I am trying to convert sequence images to video using ffmpeg command in android.
  I have build ffmpeg for android and put ffmpeg binary file in /data/local folder.
  I am running ffmpeg command using Runtime.getruntime.execute("mycommand") in Android.

  Stucture of mycommand is like this

  "/data/local/ffmpeg -r 40 qscale 2 -i /mnt/sdcard/images/img%d.jpg /mnt/sdcard/images/finalvideo.mp4" 

  mycommand contains the path of a folder where I placed all my sequence images. Running this command gives me error "protocol not found".

  Also I read that file protocol is default in ffmpeg documentation.

  How can I run such commands ?

  The Error I am getting after running simple command like ffmpeg -i /mnt/sdcard/vid.mp4

• Bambuser ffmpeg - "arm-linux-androideabi-gcc is unable to create an executable file."

  14 avril 2014, par Chaitanya Chandurkar

  I know this may be possible duplicate of some questions. but answers for those threads are not helping me.

  I am trying to compile ffmpeg library for android using Bambuser's ffmpeg.
  I downloaded Archive for client versions 1.3.7 to 1.6.0. from bambuser.

  I followed instruction given in REAME.
  While running ./build.sh i came across following error

  arm-linux-androideabi-gcc is unable to create an executable file.
  
  C compiler test failed.
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from SVN.  If the latest version fails, report the problem to the
  
  ffmpeg-user@mplayerhq.hu 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.

  Here are last few lines of config.log of ffmpeg

  mktemp is /bin/mktemp
  
  check_ld
  
  check_cc
  
  BEGIN /tmp/ffconf.qflVj27Q.c
  
      1   int main(void){ return 0; }
  
  END /tmp/ffconf.qflVj27Q.c
  
  arm-linux-androideabi-gcc --sysroot=/home/chaitanya/android/android-ndk-r5b/platforms/android-8/arch-arm -c -o /tmp/ffconf.gc6um0Ki.o /tmp/ffconf.qflVj27Q.c
  
  arm-linux-androideabi-gcc: error trying to exec 'cc1': execvp: No such file or directory
  
  C compiler test failed.

  in tmp i do not find any relative folder or file as per config.log says "ffconf.qflVj27Q.c".

  I am doing this on
  1. Ubuntu 11.10
  2. OpenJDK 6
  3. android-ndk-r5b

  NOte :
  I only have API-10 Installed in eclipse. (if it matters :D)

  What could be the solution for this ?

• Echoprint-codegen perpetual "error" :"could not decode" from shell_exec

  16 janvier 2016, par sid405

  I am trying to run codegen from popen (shell_exec creates the same scenario) in php in my Mac lion MAMP box as follows :

  $handle = popen('echoprint-codegen "/Applications/MAMP/htdocs/projectx/codegen/2.mp3" 10 30', 'r')
  
  
  
  echo "'$handle'; " . gettype($handle) . "\n";
  
  $read = fread($handle, 2096);
  
  echo $read;
  
  pclose($handle);

  But i am perpetually met with

  "error":"could not decode", "tag":0, "metadata":{"filename":"/Applications/MAMP/htdocs/projectx/codegen/2.mp3"}}

  No matter how i format the cmd inside the handle, with various variations of single and dbl quotes i still get the same thing.

  codegen is in the path and so is ffmpeg.

  Here’s the kicker. Codegen works fine from command line and so does the php script with the popen() or the shell_exec().

  From browser it won’t work.

  Any ideas ?

  Thank you in advance
