I try to use tag audio. Convert mp3 to ogg use
ffmpeg -i "123.mp3" "1234.ogg"
Server response content-type for .ogg like video/ogg. I try content-type audio/ogg and application/ogg but it doesn't work too. I think my file have got wrong format, because in player it works. How to correct convert file from mp3 to ogg in linux console?
