does this library work with opus files?

[kannanth]

I have an opus file (with extension .opus) that I'm trying to play using Origami in my iOS 8 app. I was debugging through and found out that it only supports files with the following extensions.
{
3g2 = CoreAudioDecoder;
3gp = CoreAudioDecoder;
aac = CoreAudioDecoder;
ac3 = CoreAudioDecoder;
adts = CoreAudioDecoder;
aif = CoreAudioDecoder;
aifc = CoreAudioDecoder;
aiff = CoreAudioDecoder;
amr = CoreAudioDecoder;
au = CoreAudioDecoder;
caf = CoreAudioDecoder;
cue = CueSheetDecoder;
m4a = CoreAudioDecoder;
m4b = CoreAudioDecoder;
m4r = CoreAudioDecoder;
mp1 = CoreAudioDecoder;
mp2 = CoreAudioDecoder;
mp3 = CoreAudioDecoder;
mp4 = CoreAudioDecoder;
mpa = CoreAudioDecoder;
mpeg = CoreAudioDecoder;
snd = CoreAudioDecoder;
wav = CoreAudioDecoder;
}

I'm getting a "Error:Couldn't open source". To be more specific, the file is opus encoded within an ogg container.

Any thoughts as to I how I should proceed?

Thanks

Just wanted wanted to add,
I see that the there is a plugin folder with opus decoder, but I did not get it when I setup the project using cocoapods - to which I'm a newbie (absolute first project). I used a podfile with following.

platform :ios, '8.0'
use_frameworks!

target 'MyOpusPlayer' do
pod 'OrigamiEngine', '~> 1.0.14'
end

There is a separate subspec for an opus support.

Thanks, I have managed to get it to comiple and play the opus file. But the playback is very slow and choppy. When I playback the file in FireFox (renaming the extension to ogg), it plays fine.

Here's the link to the file. Its a very small file.

Any thoughts?

Works like a charm. Thank you.

Just a quick follow-up question. After the url finishes playing, the
engineExpectsNextUrl gets called (as expected), but returning nil from
this does not seem to have an effect, this method gets called repeatedly.
Is this the expected behaviour?

there is an issue about this bug: #52, but I haven't looked into it yet.

Got opus working with these tips! GREAT.
But somehow your fix commit did not make it to the version you get via cocoa pods. Had to apply your fix again.

Would be great to see you updating this project :)
