Now I have specified the ffmpeg folder as you wrote, and it tries to download and save as MP4, but the ffmpeg version is too new for my computer and it can't start and finish the video. So the downloaded temporary files are deleted automatically and I still have no working MP4 video... :-(
PS: I did't find an address for support emails in your profile
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.
