FFmpeg VS freac

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.

Seconding basically everything that's been said here, but should you ever find yourself in need of a good file converter, I like and use fre:ac (www.freac.org), an open source Swiss army knife for audio formats.

That's a lot of steps! I believe there's FLAC rippers for Tidal, that may make it easier to use WebMD or SonicStage. I use https://www.freac.org/ to convert from FLAC (which I rip my CDs in) to WMA Lossless (which SonicStage can use) - Web Minidisc can use FLAC directly, as well.

You might want to use a tool like https://www.freac.org for the conversion.

I use fre:ac personally - https://www.freac.org

A lot of bootlegs are already ripped and available. wondering if the ones you have are the ones that are already available. you can download https://www.freac.org/ and rip em.

https://www.freac.org/ my go-to for a loooong time

What I was doing when I want 352k AT3+ files was to use https://www.freac.org/ to convert FLACs to WMA Lossless files which SonicStage 4.3 can read, then hook up the HiMD machines, pick the songs/album/whatever, and transfer them at 352k. It does the transcode on the fly but you can pick "fast" vs. "quality" modes, either should really be good but I did "quality" because the 10-year-old computer I'm doing it on should be 2-5x faster than an average computer in 2007 when SS4.3 was released so it's not that big of a deal.

If you need to convert FLAC/AAC/ALAC/whatever to a format SonicStage supports (LPCM WAV or lossless WMA) - you can use a tool like the Free Audio Converter (FRE:AC).

For lossless or high-resolution audio, I use a tool called FREAC to convert FLAC/ALAC and anything else SonicStage itself can't use to WMA Lossless, which gets you both proper metadata support and CD quality lossless files.

fre:ac does pretty much everything you could want: https://www.freac.org/
