Opus audio in AVI files???
According to a *BLEEP* who has hijacked the article "Comparison of video container formats" @ wikipedia, Opus audio is supported by the AVI container
Since he's just an elaborate parrot, here are my questions: 1) are there any sample .AVIs that contain Opus audio? 2) if the answer to the above is "yes", then how they are created? According to the help screen of the command-line Opus encoder, it's possible to create constant-bitrate streams. But I don't know whether such streams are strictly-CBR or actually just average-bitrate... Also, I am aware that there is no TwoCC for Opus audio. Of course there exists a GUID number for Opus which could be used with the WAVE_FORMAT_EXTENSIBLE thing, however I don't know any application capable of writing an "elementary stream" of Opus audio...

Anyway, since Opus was created originally for the Ogg container, I serious doubt the Xiph people would not intentionally make things harder for anything created by Microsoft |

since ogg vorbis is possible in avi (see: https://cdn.hackaday.io/files/274271173436768/avi.pdf) I don't really see a problem from putting opus in it,....

Sadly the "editor" who hijacked the Wiki article about multimedia containers has ZER0 experience with digital audio and digital video, he is merely a "bureaucrat" so to speak... The idiot even ignores that the VP codec series created by On2 has been stored in AVI files since the year 2000 or so -_- |

Out of interest...
Why do you want to mux Opus audio into the .avi container? Are you bored?
