Good news here and thanks for this.
The free VST video player are very hard to find.
mediaVST is really very simple and easy to use and with the proper codecs installed it can play any video format. Only one file and that’s all.
I found two other plugins, these are the links for download.
1) videoVST
https://sourceforge.net/projects/videovst2/
You have to compile it from the source code (with a lot of requirements for compiling).
I don’t want to install all that stuff for one plugin. if someone is able to compile it to get the .dll file, let me know please.
2) MoviePlayer
http://www.groc.org/movieplayer/
It requires QuickTime and Pluggo runtime to be installed. See the instructions on the web page.
It doesn’t work well as the mediaVST but… at least it works!
