Exporting compressed file/s in Matroska contatiner (.MKA)

[albertomaria965]

Good evening everybody!
First of all Thanks a lot to Enzo and to all the persons who collaborate to this FANTASTIC multiplatform Application!!
An additional thanks to Enzo even for the Efforts to keep the project updated (code and codecs too) and developed after the 2023 last official release.
It is a lot of time that I use the Opus Codec and most of the time I recode Flac files into one single .opus, that, if not wrong, should be a ogg (called .oga) container. Unfortunately so far most of the audio players (excluding Foobar in windows that form my point of view is impressively powerful/smart... hope they will improve in Android too) don't read the internal tags of the .opus... Unless there is the related .cue file present in the folder. Recently I started to use The Fooyin audio player which, beyond VLC, less versatile for audio, loads the .MKA reading the chapters/songs within that container. So, I was wondering if it were possible, considering the versatility of the matroska container (can hold aac, ogg, opus, mp3,flac, mpc V.8 and on and on). I was wondering If You could add that container (MKA) as destination. At the moment I use a simple bash script which uses MMPEG which loads the .opus (with chapters) and convert it in .mka still with chapters.
Thanks again in any case... Regards Alberto
