as you know showiframe can just show just one .mvi file at a time, with a wildcard tool you can show more files one by one, what is this good for? you can i.e. show more bootlogo splashs or when you convert .jpgs into .mvi you can use it as a picture viewer, you don´t need enigma2 for that, to avoid "video device busy error" while starting the tool just kill enigma2 with init 4 or switch to radio mode

what I am missing is a shuffle option, if a C specialist can add it would be nice, C source code and armhf binary are included
