• ffmpeg not working in other directory same encoder

  14 mars 2018, par Moein Hosseini

  I’m using a script to convert mp3 file to ogg file by libopus codec.

  when I use it in my home directory it works using this command :

  ffmpeg -i music.mp3 -c libopus out.ogg

  but when I’m in this directory :

  /home/moein/Desktop/BeatkhorBot/music

  the command does not work and gives me this error :

  Invalid encoder type 'libopus'

  does anyone know how to fix this ?

• ffmpeg binary for android not working

  29 juillet 2014, par Abdul Qadir

  I’ve copied the ffmpeg binary provided here in the res/raw folder into my project’s assets folder. Whenever I need to run ffmpeg commands, I copy the binary into data/data/my-package-name/ and run the following command to check if everything works.

  Process process = Runtime.getRuntime().exec(ffmpegBinaryFilePath + " -version");

  I get the output by logging the stream by process.getInputStream(). Everything works as expected. But the binary provided in the project is old (version 0.11.1) and I also need to enable lame library to work with mp3 extension. So I decided to build my own binary. I’ve build using this script and also another script showed here. When I place the build binary into my project’s assets folder. I get no output when I run the code above i.e. the log is empty. I’ve also tried building with this script but it doesn’t create any binary i.e. there is no bin folder when compilation is finished.

  I’ve made ndk related changes to these scripts i.e. changed NDK, PLATFORM and PREBUILT variables (I have ndk10 64bit) and changed --enable-shared --disable-static to --disable-shared --enable-static. Also cleared any references to other libraries in the --extra-cflags and --extra-ldflags. Do I need to make any more changes ? Any help would be appreciated !!

  EDIT :

  here’s the log file of my latest build
