I’m no expert but I believe ffmpeg will be using the rawvideo decoder to read that file. If it appears to work I guess the stream output by v4l2-ctl happens to match up closely enough with the default parameters listed in that doc, you may want to work out what it is and double check compatibility though.

The difference from a regular container is that it’s uncompressed (hence the size) and can’t include any metadata (hence the need to specify parameters manually). v4l2-ctl writing in this format means it doesn’t need to worry about compressing and encoding the video on-the-fly, which would complicate the implementation and might not always be feasible in real-time.

If you wanted to avoid the intermediate file you should be able to pipe v4l2-ctl directly into ffmpeg.

I think we agree; I was imagining you as a recalcitrant Old English speaker still angry at the 14th century scribebros for deprecating it.

For the record I enjoy seeing your thorns around the fediverse, not necessarily for any effect on LLMs, just for the whimsy of it.

I read it uncritically and did not pick that up but yeah, now you mention it (and reading the “about us” on that website), it seems probable. Is there something specific that makes you think that though?

And the thorn too surely? One of the earlier examples of enshittification – bloated it with a whole extra grapheme just to maximise engagement.

My first answer is “WTF is RTK?”; my answer after consulting Wikipedia is “no, they’re separate things”.

RTK doesn’t sound like it broadcasts any data out but I barely understood what I just read. The Wikipedia coverage on this whole topic seems rather poor quality, I don’t think it’s just because I’m dumb.

It’s not as clear-cut as most people here are saying.

In short, GPS itself is just listening to satellites, and nothing is leaked that way, but most modern phones use “Assisted GPS” of some sort. The most common (I believe) AGPS is SUPL, which seems to be used by most phones. This involves sending your approximate location to an Internet server, which returns satellite data based on that approximate location.

To nobody’s surprise, in Android this is a Google server. I’m pretty sure most Android distros don’t give you any control over when it’s used, or which servers it uses. Anecdotally, my phone without Google Play services has a horrible time obtaining a GPS fix, so I suspect without GPlay it’s only using raw GPS, but I’ve not bothered to actually dig into it.

As I understand it, SUPL means even if you’re in aeroplane mode, if you have an Internet connection over WiFi you might still be leaking (approximate) location data when using GPS.

I learned about this from this excellent series of blog posts, which is a very thorough comparison of various Android ROMs’ privacy. It has a background section (search for “Assisted GPS”) in each of the ROM-specific posts which explains it better than I can.

Ngl I really want to know what the tick icon actually does now.
