Error when exporting to Opus format

Permanent link to this post Posted by jimmyhosen » Fri Dec 29, 2017 12:54 am

Hello, I get the following error when attempting to export to Opus format:

FFmpeg : ERROR - Can't open audio codec 0x4f505553

Here are the parameters I was using:
Custom FFmpeg Export
Open custom FFmpeg export options
Format = opus
Codec = libopus
Bit rate = 224
Sample rate = 0 (no change)

Any ideas?

Other details...
Audacity 2.2.1
FFmpeg library: F(55.33.100), C(55.52.102), U(52.66.100)
...and Audacity says that it found "valid" FFmpeg libraries when I click on "Locate...".

I don't think that opus format is supported yet, even though I see it listed as an option in the FFmpeg settings.

I notice that opus is listed as a feature request here: https://wiki.audacityteam.org/wiki/Feat ... rt_Formats would you like me to add your 'vote' for "Native Ogg Opus support"?

Hmm... I thought Opus had its own native container, ".opus". I suppose it could alternatively go into an .ogg container. I tried exporting to .opus.

Maybe I should also try .ogg?
