• How to convert a .m4a file to a .wav file on Android using React Native ?

  23 octobre 2022, par aurelien_morel

  I am trying to convert a .m4a file that I record using expo-audio into a .wav file. The goal is then to use it as a blob to send it on a Google Cloud Storage.
I tried to do this using ffmpeg-kit-react-native :

  


  const uri = recording.getURI();
console.log(uri);

if (Platform.OS === 'android') {
    FFmpegKit.execute(`-i ${uri} temp.wav`).then(async (session) => {
    // const returnCode = await session.getReturnCode();
    uri = 'temp.wav';
    });
}

const response = await fetch(uri);
const blob = await response.blob();


  


  but I have no sucess (getting the error) :

  


  TypeError : null is not an object (evaluating 'FFmpegKitReactNativeModule.ffmpegSession')

  


  uri have this form :

  


  file :///data/user/0/host.exp.exponent/cache/ExperienceData/%2540aamorel%252Fvoki/Audio/recording-4038abed-f264-48ca-a0cc-861268190874.m4a

  


  I am not sure if I use the FFmpeg toolkit correctly. Do you know how to make this work ? Or is there a simpler way to do it ?

  


• UDP Streaming with ffmpeg - overrun_nonfatal option

  21 octobre 2022, par Julien Greard

  I'm working on a software which uses FFMPEG C++ libs to make an acquisition from an UDP streaming.

  



  FFMPEG (1.2) is implemented and running but I get some errors (acquisition crashes and restarts). The log displays the following message :

  



  *Circular buffer overrun. To avoid, increase fifo_size URL option. To survive in such case, use overrun_nonfatal option*

  



  I searched online for documentation about how to use this option, but I only got informations about how to use when running directly ffmpeg executable.

  



  Would someone know how to set the correct option in my C++ code to :
- increase fifo_size
- use overrun_nonfatal option

  



  Thanks
