oech3 [1] filed a deletion request for opera-extras [2]: This and opera-ffmpeg-codecs provides aac and h264 to opera. The reason this was submitted is opera-ffmpeg-codecs was broken for long time. But now opera-ffmpeg-codecs is fixed. This also have unsynced Chromiumver: https://nwjs.io/versions.json . Upstream is also same: opera-extras internally fetches Chromium src while opera-ffmpeg-codecs use part of it.
