Hi all

I have a library of karaoke in MP3+CDG format (i.e. an MP3 file for audio, plus a binary CDG file containing the karaoke graphics). Ffmpeg is able to convert these to a real video format fairly easily, but they take up significantly more space.

So, my question: will ffmpegfs support these in the source directory? I'll give it a try myself when I get a chance, but asking in advance so I don't wake my time if someone already knows it won't.

Thanks in advance
