• How to build the Exoplayer ffmpeg extension with the GSM codec ?

  4 mars 2020, par MadCoconut

  I wanted to use Exoplayer to play an audio file but when I tried I got this exception :

  2019-12-13 10:08:14.827 28972-29388/com.XXX.XXX E/ExoPlayerImplInternal: Source error.
  
      com.google.android.exoplayer2.ParserException: Expected block alignment: 0; got: 65
  
          at com.google.android.exoplayer2.extractor.wav.WavHeaderReader.peek(WavHeaderReader.java:81)

          at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:636)
  
          at java.lang.Thread.run(Thread.java:764)

  The audio files I have to play are wav files (GSM_MS, 13kb/s)

  I tried to build the the Exoplayer Ffmpeg extension following the tutorial :
  https://github.com/google/ExoPlayer/tree/release-v2/extensions/ffmpeg

  I cloned the Exoplayer repository and I downloaded the Android NDK version r20b.

  I modified the build script build_ffmpeg.sh to enable the libgsm :

  COMMON_OPTIONS=“
  
  …
  
     —enable-libgsm
  
  "

  I defined the required environment variables :

  • FFMPEG_EXT_PATH=“/extensions/ffmpeg/src/main/jni”
  • NDK_PATH="/Users/USER/Documents/Android/android-ndk-r20b/"
  • HOST_PLATFORM(“darwin-x86_64”)
  • ENABLED_DECODERS(all the decoders available https://exoplayer.dev/supported-formats.html#ffmpeg-extension)

  Then I built the library using the provided command line :

  cd "${FFMPEG_EXT_PATH}" && \
  
  ./build_ffmpeg.sh \
  
   "${FFMPEG_EXT_PATH}" "${NDK_PATH}" "${HOST_PLATFORM}" "${ENABLED_DECODERS[@]}"

  But something goes wrong during the build process :

  remote: Enumerating objects: 38, done.
  
  remote: Counting objects: 100% (38/38), done.
  
  remote: Compressing objects: 100% (26/26), done.
  
  remote: Total 26 (delta 20), reused 0 (delta 0)
  
  Unpacking objects: 100% (26/26), done.

  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 "ffbuild/config.log" produced by configure as this will help
  
  solve the problem.

  The gsm.h file is located there : /extensions/ffmpeg/src/main/jni/ffmpeg/libavcodec

  I assume this path has been configured to be used by the build script.

  Any help is much appreciated.
