Reading an interesting discussion over on r/rust from the past week. One of the moderators talks about the difficulty in moderating AI slop projects - https://www.reddit.com/r/rust/comments/1uwmef6/comment/oxkltxi/

But I think the top replies hit on a really good idea:

>“I built a thing in Rust” just isn’t that interesting a topic—AI or otherwise—and IMO we’d be better off without posts like that at all. If you built a fast new BitTorrent client, that’s of interest to BitTorrent users, not the Rust community.
>
>A library that lets me do a thing I couldn’t before? Very useful! A new approach to solving a problem that’s historically frustrating in Rust? Amazing. Questions on how to deal with some issue? Welcome aboard.
>
>But I couldn’t care less about “{project} in {lang}” for all values.

and

>r/cpp moderator here, we have a designated Show & Tell pinned post. We make exceptions only for established projects or blog posts talking about your project.

>(And then remove AI slop)

One of the recurring issues in trying to moderate the flow of slop is having to constantly make a judgment call of just HOW "slop" it is and whether it crosses a line. Why not cut the problem off at the source: you simply cannot post an "I Built (Whatever)" here (with very few exceptions, etc). There's no need to make this a judgment call about AI/LLMs at all, neatly sidestepping the various arguments about the whole thing.

I personally do not feel like much would be missed!

I am a bit confused about the interaction between -x and -ba (or, -f bestaudio) specifically for grabbing audio. I have ffmpeg available and plenty of space / bandwidth, so remuxing is not a problem.

What I want is for yt-dlp to take a URL, figure out the "best" available audio (whether that's from an audio-only stream, or the audio portion of a highest quality video), go get it / demux if needed / and produce a single audio file at the end.

My confusion is that (as far as I understand it) -x means "download the best Video, throw away the video track and keep just the audio" whereas -ba means "download the best Audio-only track, never download a video track" (I think?).

These are similar but mean different things.

What if the best audio is only available as part of a combined video+audio stream? Wouldn't -ba ignore that? But on a different site, the best format is in an audio-only high bitrate m4a or something, so -x might overlook it and get the best Video instead?

What is the magic combination of flags to always get the best-available audio track, in ANY container?
