• How to decode Full Rate GSM Audio file ?

  29 août 2012, par AndroidLearner

  I have to decode a full rate gsm audio file. Full Rate GSM Audio file is decoded using libgsm. I have used MSVC++ with windows nightly builds of ffmpeg and libav but unable to decode file correctly. Can anyone tell me the reason ? I have tried decoding using following codecs :

  log : Print a full backtrace along with error messages under Valgrind
  Useful to understand where and in what execution state a certain message
  
  is generated. It is enabled only when optimizations are disabled, since
  
  function names are not printed otherwise.

  vulkan_shaderc/glslang : print full shaders on TRACE rather than VERBOSE
  Way too spammy.
