OK, we have successfully guided you to set up FFmpeg with CYS properly, you can see that CYS does its job perfectly, it downloads the files and runs FFmpeg - but your computer is not up-to-date enough to run FFmpeg? And you still feel our work only merits 1 star - in what Universe is this fair??

Seriously, we provide something of value here for free, with no strings attached. A bare minimum would be for users to respect the work we do, by being fair to us, and by reading the helpful information right in front of their eyes, so that we can spend our limited time with developing the program.

The information you missed is explained and illustrated on our web site. The links to our web site, FAQ, and support email address are to the right of the top of the description section on this add-on page.

On your specific problem: please, send us an email to our support address, and tell us your operating system and CPU. Short of upgrading your CPU, you might get lucky with a not-so-old FFmpeg version that can already mux DASH files and still runs on your system.

We are sorry you are having a problem, but at least this time you have given us some background information about it, thus now we can actually help you!

That you see MP4V in the menus and Options at all indicates that CYS does not know where to find FFmpeg on your system. You seem to be missing a crucial step in setting up FFmpeg with CYS, step 3 on the following page:

Just make sure you navigate to and select the *folder* containing the FFmpeg executable, not the executable file itself. This is needed to ensure it works properly on Windows, Linux or OSX.

We hope you will now be able to start enjoying CYS! Please, send bug reports and support requests to our support email in the future. Thanks
