Subtitles can be hard coded into the video with mencoder. The command

$ mencoder video.avi -sub subtitles.srt -o videosubtitles.avi -ovc lavc
-oac copy

But your basic problem remains unsolved. mencoder can build a video from
frames and you can mux the audio with mplex or some such thing.

All this means a bit of effort.
