Add support for Opus audio
« on: February 22, 2016, 02:33:30 am »
Hi,

It would be great if sfml would support opus as audio format.
Opus is a free / open audio format and at the moment the codec with the
best quality per bitrate, at least for low bitrates (< 100kb/s) but still good at higher bitrates.
It was developed to replace speex and gets now more and more used for VoIP applications,
because it provides very low delay (see:  wikipedia).
But it provides also better compression then vorbis or mp3 / aac and most other lossy codecs,
with better compression I mean better quality / bitrate, for a comparison see:



I personally use it for all my audio files, because I do not need loss less audio in my games.
And especially voice, which is often used in games, can be compressed at very low bitrates without noticeable quality loss ( <96kb/s).

Yesterday I merged my custom changes into a sfml fork, so you can try it your self:

Feedback is very welcome :-)

It's fun how they chose the exact same API as libvorbis. This makes the implementation is a lot easier.

We are all busy, but if a proper PR is submitted, I'm sure it can be integrated soon.

Looks like OP is working on it. So he may be planning on submitting a PR.
