Description
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.
