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

Ffplay : Change filter options while playing audio
11 février 2018, par arthaI am trying to apply equalizer filters to ffplay while it is playing an audio. Is it possible ?
Like start playing the audio with the command :
