Audio recorded with MediaRecorder on Chrome missing duration
27 octobre 2016, par suppp111I am recording audio (oga/vorbis) files with MediaRecorder. When I record these file through Chrome I get problems : I cannot edit the files on ffmpeg and when I try to play them on Firefox it says they are corrupt (they do play fine on Chrome though).
Looking at their metadata on ffmpeg I get this :

I am trying to record the voice in audio/wav formate but its recording in video/webm formate not because of \<const mimetype="video/webm">. Whatever the mimeType I am giving its showing the file type video/webm on "https://www.checkfiletype.com/". I am recording it for the speech_recognition used in flask backend which is accepting only audio/wav.
So in frontend I have written a function "convertWebmToWav " which is giving me the error :
Uncaught runtime errors:
