Bug#1005082: Exporting to .opus impossible

["Peter Mueller" <petermueller@ro.ru>]

Package: audacity

Version: 2.4.2~dfsg0-5

I use debian stable. When trying to export an audio track to OggOpus, I get an error message, “FFmpeg: Kodieren des Frames fehlgeschlagen”. The message occurrs right at the very beginning; I presume that no conversion has taken place so far. This failure message, though succint, is in reality not very useful because I don't know whether it's a program bug or whether (and how) to recover from it. I expect that instead, the exporting either just works or that a message is output that helps me to make it work or to abandon my attempts. Is it a real bug? Has such a conversion been implemented at all? Are audacity-ffmpeg communication logs stored anywhere?
