Issue Title (help a newbie )

try to use with vs2022 and .NET 6 I try to use this application with Nugets. I put in c:\ffmpeg all the bin from : https://github.com/BtbN/FFmpeg-Builds/releases ffmpeg-master-latest-win64-gpl-shared.zip ' I have the error "System.IO.FileNotFoundException: 'Unable to load FFmpeg binaries from folder 'c:\ffmpeg'.'" when I start the code below

' My questions : a) is it a good choice to start with vc2022 / .net 6 for your library ? b) do I have to choose a specific version of ffmpeg? (I took the last one) c) do you have a simpler example, like initializes and just plays a video file (your demo is already a bit too sophisticated for a beginner) Merci, have a good day. LauraKami

Hi,

You need to have both ffmpeg 5.x (which you already have because you downloaded the lates release) and ffmpeg 4.4. Also make sure that you are compiling for x64 and not accidentally for x86 or the x64 binaries won't work. And when you install ffmpeg 4.4 make sure to only copy the dll files so you don't overwrite the 5.x exe files. Hope that helps, took me a while to figure that out as well.

Sincerely StrikingPopcorn

Merci @StrikingPopcorn, Yes the problem was the library, I download a v5 library and the required is 4.4 library So, some solutions

Use the old Nuget ~~https://www.nuget.org/packages/FFmpeg.Shared/~~ , it's appear in list when we search 'FFME' ===> don't do that, this nuget don't work anymore, it's too old.
Build your own library, yes good, but for newbie ?
Search in the link https://github.com/BtbN/FFmpeg-Builds/releases , why is not indexed, I scroll 12 pages before found it.
so now, use this link : https://github.com/GyanD/codexffmpeg/releases/tag/4.4.1 for 4.4.1 last version of 4.4 https://github.com/GyanD/codexffmpeg/releases/tag/4.4 4.4 first version. But read the Readme ... this build is only with License: GPL v3., for LGPL version, probably you must build yourself the library.

So, yes it loads and play a video, Thank's again @StrikingPopcorn. And for UnoSquare : put the links in your doc, they are stable and official link. Have a good day, LauraKami

@LauraKami @StrikingPopcorn Thanks a lot, I've wasted a lot of time because I didn't understood that https://github.com/GyanD/codexffmpeg/releases/tag/4.4.1 was also required; it should be made clearer IMO in the readme file
