Generic refactoring

[AlexPresso]

This PR aims to help the VideoStation's patch and MediaServer's patch to work together (i.e. you want to patch VideoStation + MediaServer).

Changes:

• Make CodecPack (Advanced Media Extensions) patch standalone : CodecPack is not anymore relying on VideoStation's patched files to work. It's safer this way, as VideoStation can be removed without breaking CodecPack features.
• CodecPack patched ffmpeg files (ffmpeg33, ffmpeg41 and/or ffmpeg27) are now trying with CodecPack default ffmpeg files before trying to use SynoCommunity's ffmpeg. Again, it's safer for other applications also relying on CodecPack's ffmpeg to work.
• Group gstreamer patched libraries and plugins into same directory to make it easier and safer to remove.
• Make the wrappers work in a more generic way
• Code cleaning

Sorry to ping you, but if you mind testing this new patcher using the previous comment procedure, it would be highly appreciated

Hello Alex,

im already on it but as soon as it restarts in script videostation it reindexes all files.
It i start in the meantime the install script and it restarts videostation again it trashes all my database.
But the Problem has always been there and nothing to do with your script.
It just takes a Moment 😉

Yeah it also happens to me sometimes ahah, I have to reindex everything, it's quite annoying, but I guess Synology don't want to work on fixing that

Thank you very much :)

So script ran smoothly and no problems so far. Playback is fine and i have a file in offline transcoding but it still needs about 20min to finish 👍

update:
Transcoding finished without any issue 👌
