Add support for .webm files (containing an opus audio stream)

cedric

I'm using yt-dlp to download youtube video's. These video's are saved as .webm files. Strawberry does not show these files in the collection.

I suspect the backend can play this file, as ffprobe reports the matroska container to contain an opus audio stream:

@cedric Wasn't the .webm format a video format? Strawberry is a music player, not a video player. If you're trying to download only audio, you should use another tool to download YouTube videos (MediaHuman for example, supports MP3 for downloads).

WebM is an audiovisual media file format. It is primarily intended to offer a royalty-free alternative to use in the HTML5 video and the HTML5 audio elements. It has a sister project, WebP, for images. Wikipedia
