I'd like to provide the VOB file but I can't for legal reasons. I tried to cut the file (with `dd`) to give a ""small sample"" but `ffprobe` behaviour seems to depend on the length of the resulting VOB file (with 10MB, all the audio streams are found but non of the subtitles streams for instance; at 500MB, just one audio stream is available). `ffplay` can successfully play the file but I am not sure I can actually choose the audio stream I want. I can provide anything you might consider usefull. Thanks for your help. ==Important note== I am sure all the VOB files I concatenated actually contained parts of the movie (all of those were needed otherwise parts of the movie just disappear). `mediainfo` reports a menu stream (and that might be the reason why `ffprobe` reports wrong streams). But as I said, every VOB files I used are needed. So, if you know any way to extract precisely menu-related stuff from the VOB, please let me know. (I'd like to avoid mplayer or avidemux: those depend on too many useless things like dbus or avahi) ==Software version== ffprobe 0.8 libavutil 51. 9. 1 libavcodec 53. 7. 0 libavformat 53. 4. 0
