• File conversion to mp3 returning failure everytime using flutter package ffmpeg_kit_flutter

  6 novembre 2024, par Sanath balthar

  I am trying to convert a .wav audio file generated from a flutter's text to speech package - "flutter_tts" to mp3 file but it is failing everytime.
I have written the below code for file conversion. I have imported the package ffmpeg_kit_flutter. It doesnt even show why the conversion is failing.
I have looked up in stackoverflow and other sites but could not find any relevant solutions. I am using vscode as editor. I have attached flutter doctor output below as well. Could anyone please guide me ? Let me know if you need more information.

• Should I open source my source code when I rebuild ffmpeg and dynamiclly link to my program ? [closed]

  20 septembre 2024, par openjz

  I have a c++ program developed on visual studio 2022, and my program need to work with ffmpeg, I rebuild it and I don't know if there is open source problem.

  


  I rebuild ffmpeg for windows msvc paltform (according to https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC) by customize the build configuration, but I don't modify the source code and build script of ffmpeg, and I don't enable gpl or gpl v3 in the build configuration, ffmpeg is dynamiclly linked to my program, I'm sure that the only license I should concern is the LGPL-2.1 or later, in this case, if I want to distribute my program for commercial use, should I open source my source code ?
