Hello all, I'm encoding my audio files to opus, with the following command: > ffmpeg -i test.mp3 -acodec libopus -b:a 64000 -vbr on test.opus (Debian squeeze, ffmpeg version 3.3.5)
According to wikipedia, the "opus" container should just be an ogg container (https://en.wikipedia.org/wiki/Opus_%28audio_format%29). However, encoding my file with an ogg extension : > ffmpeg -i test.mp3 -acodec libopus -b:a 64000 -vbr on test.ogg produces a different file from the previous one (md5 are mismatched). Indeed, ffmpeg tells me so : "(...)Output #0, ogg, to 'test.ogg':(...)" instead of "(...)Output #0, opus, to 'za.opus':(...)" However, the "file" util view both files as ogg : > file test.* test.ogg: Ogg data, Opus audio, test.opus: Ogg data, Opus audio, What's going on here ? What is the container used when encoding a file to ".opus" ? Which one should I use (I'm aiming for maximum compatibility, mainly with android phones) ? Thanks for reading !
