How to convert amr to flac with ffmpeg?

Question

css

Using phonegap, you need to convert files to flac, commands that
shell_exec('ffmpeg -i '.$dir.' -vn -acodec flac -ac 1 -ar 8000 -f flac -y '.$output);
He creates the file without problems, only the flask is not a flask there, but a complete slag, you need a valid flask for google speech api.
Because the fongapa does not write no in mp3, not in vav, or rather, you can put .mp3, etc., but at the output, as I understand it, amr anyway (judging by the output recording)

Answer 1

Duck slick and do it, just through 2 sliders.
When generating a navigation slider, generate a click on the slickGoTo slide on the right slider.

Answer 2

You can take responsive slides and adapt it.
The implementation with switches - dots is already there. On pictures with a small preview, you can hang the same classes or links as dots. I think you'll figure it out, the documentation there is small and simple, and the slider itself is fast and lightweight, weighs little.

Answer 3

As a minimum, start with a basic one ffmpeg -i audio.xxx -c:a flac audio.flacand then tweak the settings
or take oga

avconv -y -i "${i}"-c:a libvorbis -f ogg "${i}.oga"
