Those methods are sub-sample accurate, granted you call them a bit in advance to account for the cross-thread communication, as you say. But yes, in general this was designed (prior to me becoming an editor) with scheduling in mind, not wit

`jj commit -i` (or a lot of commands `-i`) and maybe `snapshot.auto-track="none()"` in the config, to a certain extent is what I use. I used to do the same with mercurial. In practice, I also use `absorb` a lot, that leaves unrela

It does not, it serves no purpose for only listening to music. Producing, broadcasting, or any sort of scenario that require reliable low latency can benefit from a real time kernel, but not merely listening to music.

Indeed. I work on the Firefox media stack and we have been grabbing wake locks when video playback is happening for a long time. Occasionally e.g. on some linux desktop variant this has malfunctioned and we're alerted in no time and fi

Yes, I use rr all day every day (to record Firefox executions) on a rather recent Threaripper Pro 7950, and also with Pernosco. The rr wiki on GitHub explains how to make it work. Once the small workaround is in place it works very reliably

The way this works (and I'm obviously taking a high level view here) is by comparing what is being played to what is being captured. There is an inherent latency in between what is called the capture stream (the mic) and the reverse st

We've been working on the Web Codecs API for a few years now. It only handles encoding and decoding media codecs, ffmpeg does much more (container handling, filters and everything needed really). Web Codecs can take a compressed media

We've put a dedicated section called Media in about:support, it has decoding capabilities and other things such as audio IO informations. If you find that it is not accurate, e.g. by cross-checking via other means, please open a ticket

If you want to know the media decoding capabilities of a Web Browser, you can use the MediaCapabilities API. In Firefox, when flipping the "resist fingerprinting" flag, it's spoofed appropriately based on a study of what the
