Thank you for your elaborate and informative answer.
Yes I do understand that.
I also wonder for a while what can be the issue in doing the portage and how we could maybe help, I'm sure that it is not impossible to do it and that we can find a way. Since however you have been absolutely silent on the project, there is no way for us to know if you are even working on it.
I would be more than happy to use an alternative app and leave you in peace but you are the main video playing app on all platform and since I use VLC on my PC, phone, tablet etc.. I figured I could hope to use it on my Chromebook too.
