[asterisk-users] "Cannot write OGG/Opus streams. Sorry" - any ideas?

[Jonathan H]

So as y'all know, with your help I managed to get Opus installed at last. Yay!

With excitement, I wrote my dialplan, dialled in, and....

[Jan 28 21:30:11] ERROR[29977][C-0000001d]: format_ogg_opus.c:95
ogg_opus_rewrite: Cannot write OGG/Opus streams. Sorry :(
[Jan 28 21:30:11] WARNING[29977][C-0000001d]: file.c:468 fn_wrapper:
Unable to rewrite format ogg_opus

Any idea where I'm going wrong? I googled that error and can't find it
anywhere, nor can I find any notes about not actually being able to
*use* Opus once installed, so if anyone can point me to where I've
gone wrong I'd be most grateful!

Thanks.
