lpf-spotify-client VS FFmpeg

I imagine the answer probably involves downloading a kernel driver module for your wifi adapter - may be able to get it from rpm-fusion.

After I installed my system, I went to rpmfusion.org/Configuration and applied their repro install steps.

AFAIK that format is no longer supported by official Fedora packages. Decoding HEIC files supposedly works when the packages libheif-freeworld and heif-pixbuf-loader from the RPM Fusion repos are installed (cf. https://discussion.fedoraproject.org/t/fedora-38-heic-problem/81790/6).

Only thing I can think that might throw you off if you use one of the Fedora spins (e.g KDE) is that it doesn't give the option to enable RPMFusion during setup. You'll likely want this as without it your system will be missing a ton of proprietary media codecs or access to non-free programs (e.g Steam or Discord). If you've installed stock Fedora Workstation you'll likely already have this I think.

In the case of the RHEL family, "large" updates only occur every six months when a new minor release is cut, otherwise there's not a lot of updates outside of security or immediately impacting bug fixes. Plus as a desktop it can be rock solid (if a bit more bare-bones) and Flatpaks can be used to get software not in the primary repos, which can be expanded via EPEL and RPM Fusion. Non-GNOME desktop environments are provided via EPEL, and RPM Fusion contains useful software like drivers and patent encumbered codecs (usually installing ffmpeg-libs will solve all your problems).

Package management on this system is bewildering. Tried to install ffmpeg via rpm-ostree, got dependency conflicts. Tried to install ffmpeg via dnf inside a Fedora 37 toolbox, got "no match". Can't find it in Flatpak. Not sure how to enable RPMFusion repos. Not sure if/how should enable COPR repo, and if that would help. https://ffmpeg.org/ sends you to https://rpmfusion.org/ , but instructions there don't say how they apply on this distro. [From someone on reddit: "Copr repos are user repos like the AUR or personal ppas for Ubuntu. ... But codecs and all are on rpmfusion."]

Possibly related to Nvidia. Did you try it on X11? Nvidia drivers from RPM Fusion might make a difference here.

Will rpmfusion.org have a guide on this or will I have to remember about this post every time I reinstall Fedora?

FFmpeg (https://ffmpeg.org/)

GPL2

Since FFmpeg is GPL2, doesn’t that require CompressX to disclose its source code?

IANAL, apologies if I miss understand license requirements.

This turns out to be a lot of assembly macros to help write one x86 assembly. https://github.com/FFmpeg/FFmpeg/blob/master/libavutil/x86/x...

The sibling comment recommending compiler intrinsics is probably the best way to go for writing SIMD code. A mixture of `` style types and intrinsics to specify instructions is a solid 90% solution compared to assembly.

If you want that last 10%, I think macros are putting the emphasis in the wrong place. They're a somewhat easy way to build up a language abstraction which will work if held carefully, but I'm confident the dev experience using this abstraction when you write invalid code will be deeply confusing.

I would suggest to write a parser instead of the macros. That'll tell you clearly when the syntax is invalid (though possibly not with much precision) and it'll give you a place to put semantic analysis for where valid syntax encodes nonsense. Do the equivalent of the macro expansions on the parsed tree instead of on the text. Emit asm as the "back end".

You might have heard of FFMPEG or ImageMagick for image and video edition in a programmatic way. MoviePy is a Python module for video editing (Python wrapper for FFMPEG and ImageMagick). It provides functions for cutting, concatenations, title insertions, video compositing, video processing, and the creation of custom effects. It can read and write common video and audio formats and be run on any platform with Python 2.7 or 3+.

There are many cloud-based tools and websites that can convert your images, but the problem with these tools is that you usually have to upload the files for them to be processed, and some of their services are not free. In this article, I'd like to introduce a piece of software called FFmpeg, which allows you convert the images locally with one simple command.

To run the demo locally, be sure to have Python 3.11 and FFmpeg installed.
