I know this request has been going on since 2011 but it really is time this software was able to be easily used by linux users. If an appimage, containing VLC (
https://www.videolan.org/legal.html) could be made available it would make life very much easier for linux users. The link on your download page for linux users is 8 years old and out of date. Although someone, somewhere may have cracked it, as far as I am aware you cannot get a windows quality experience with SE using either wine or mono. Either the OCR or the video always has some problem, and stability is also an issue. Of the mastering that I do, sound is now usable decoding, editing and reassembling in linux, video is still outstanding as is subtitles. There is really no native linux alternatives, what is available seems to be no longer supported and certainly is not as fully featured as SE.
