  All my dependencies are in place, including FFMPEG, PKG_PROG, etc but I'm getting these errors and at a loss. Any ideas ?

• 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

• arm-linux-androideabi-gcc is unable to create an executable - compile ffmpeg for android armeabi devices

  25 juillet 2013, par Chaitanya Chandurkar

  I am trying to compile ffmpeg for android armeabi devices.
  I am following tutorial by roman10.net
  His given build script builds ffmpeg for armv7-a devices. I want to build it for armeabi.
  

  My ultimate aim is to run ffmpeg commands on android armeabi and armv7-a devices.

  So i change the script's CPU part from

  #arm v7vfpv3
  
  CPU=armv7-a
  
  OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=vfpv3-d16 -marm -march=$CPU "
  
  PREFIX=./android/$CPU
  
  ADDITIONAL_CONFIGURE_FLAG=
  
  build_one 

  to

  #arm v6
  
  CPU=armv6
  
  OPTIMIZE_CFLAGS="-marm -march=$CPU"
  
  PREFIX=./android/$CPU 
  
  ADDITIONAL_CONFIGURE_FLAG=
  
  build_one

  (I thought changing it to armv6 would build ffmpeg compatible with armeabi devices. m i wrong ?)

  Doubt 1 :
  Do i also have to change toolchain ?
  i.e from arm-linux-androideabi-4.4.3 to arm-eabi-4.4.0 ?????

  Doubt 2 :

  When i try running ./build.sh (without changing toolchain) it gives me following error :
  

  /home/chaitanya/android/android-ndk-r5b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc is unable to create an executable file.
  
  C compiler test failed.
  
  
  
  If you think configure made a mistake,.. blaah blahh blaah

  after that i got lot of warnings saying :
  ‘sub_id’ is deprecated and many other function deprecated warnings.

  platform : ubuntu 11.10
  ffmpeg version : 0.11.2
  NDK : android-ndk-r5b

  Here is my build script :
