[coapp] New Linux builds available with system ffmpeg support

⚠️ this is for advanced users ⚠️

Thanks to @kuanyui work, it is now possible install, on Linux, a version of the CoApp that relies on the system ffmpeg (regular CoApp comes with its prebuilt ffmpeg).

To find the builds, just look at the noffmpeg note here: https://github.com/aclap-dev/video-downloadhelper/wiki/CoApp-Installation

Interesting . . . What is your stance on a Windows user substituting a version of ffmpeg obtained from ffmpeg.org into the CoApp directory? Have you (that's plural, Paul + Michel) made any modifications to the source of ffmpeg? Or is the ffmpeg packaged with the CoApp simply a build you guys did yourselves without any source code modifications?

By the way, some Windows users are EXTREMELY TECHNICAL with deep programming background. Ditto for Mac users. Being technical is not the exclusive purview of Linux users.

Yes. The changes are mostly about making ffmpeg less strict. But that system ffmpeg will do fine in most cases.

Sure. But the patch was for Linux.

Hmmmm..... I like the idea of less strict. I'm sure those changes have made things that were failing in VDH start to work. But then that begs the question: Aren't Linux users also going to lose the bug fixes for the cases that are cured by the less strict ffmpeg?

This is a special "noffmpeg" build for people who don't want ffmpeg. The default builds use builtin ffmpeg, not system.
