Certificate Request for matroskaplayer

[davidprojekt]

appid would be matroskaplayer, to be inline with the release name of the library this is based on, which I released under the NPM Namespace @matroska-js

Also, I want to note — one patent question I'd like your guidance on before this ships.

The app bundles a small audio-only ffmpeg.wasm core (LGPL — built without --enable-gpl / --enable-nonfree) to transcode audio tracks the browser can't decode into royalty-free AAC-LC or Opus. Video is only remuxed, never transcoded. Everything bundled is a decoder; the only encoded output is AAC-LC/Opus.

Most of the bundled decoders are either truly royalty-free (Opus, Vorbis, FLAC, ALAC, WavPack, TTA, PCM) or have clearly-expired core patents (AAC-LC, AC-3).
Two are the borderline cases I want to raise: E-AC-3 and DTS core.
Their core patents appear to have expired, but — unlike AC-3/AAC-LC — that isn't as clean-cut, and both rightsholders are active licensors.
I've deliberately excluded everything clearly still patented (HE-AAC/xHE-AAC, TrueHD/MLP, DTS-HD/MA).

So: are you comfortable with E-AC-3 and DTS-core decoding enabled by default, or would you prefer I drop either/both from the default build? It's a one-line config change, and the app already lets an admin point at a "fuller" external ffmpeg build for anyone who wants extra codecs and accepts the patent responsibility themselves. Happy to match whatever posture you prefer.

can you please fix the failing DCO check ?

the requirements are on your own
you would already need to ensure that your code is in compliance of the licenses as much as you already checked the codecs and their status
