How to keep transparency when scale webm file with ffmpeg
5 octobre 2022, par Sonia KidmanI'm using ffmpeg to scale my WEBM file, by using below command :

Convert Audio Files using FFMPEG in android
25 avril 2018, par Venkat MaddyI developing android application, Where I’ve asked to record the calls and convert them to WAVE(.wav) format and send to server.
I am able to successfully record and save the audio in my mobile. The recorded file mime type is 3gpp, now I want to convert this 3gpp file to wav. I tried using FFMPEG but unable to convert it. I am posting my code here, Any help would be grateful.
While Converting the recorded file from aac to wav, I’m getting below error
