I have been searching something which can multiplex subtitle with video files in Linux environment. The key thing is that it should softly embed the subtitle to video, not encode again. (like avidemux). After this multiplexing process, user should be able to open/close subtitle using VLC for example.
While searching that, I found a software which can do exactly what I need, named AVI-Mux GUI in Windows environment. However, I need these software's Linux alternative.
