Hia everyone, I have been endlessly trying to rip some DVD VOBs via an automated/batch approach. Some help would be greatly appreciated. Problem is I have some specifc needs/requirements as outlined below: 1) split VOB output by cell-id (to get all titles/chapters in spearate files) 2) demux video ExE0 stream to separate file...either AVI or MPEG-1/MPEG-2 format. 3) demux all audio streams (0x80,0x81,0x82,0x83,...) to separate files, preferablly in MP3/AC3 format. I need to retain all language audio. 4) demux all subtitle/subpicture streams (0x20,0x21,0x22,0x23,...) to separate files. Again, I need to retain all language subtitles and captions. I tried a whole range of products I had downloaded (some free, some demos) but not that many had commandline support. My findings of these and how they worked is below: 1) SMART RIPPER did much of what I needed, however, the split by cell-id only split the video...the audio and subtitle streams were still one file. I could always get the chapter info (location, length, #frames) and split. However, also only seems to pick out the main movie VOB...I wanted to rip/decode/demux other DVD VOBs as well for menu pics and motion menus as well as extras. 2) DBD2AVI...only seemed to make some project files. Maybe I have the wrong commandline settings here. If someone could help that would be great. 3) bbDMUX...can demux streams but no cell-id splitting. Again, could try and split up later based on chapter info. 4) DecodeVOB...can demux video/audio...but only one audio stream per run and no subtitle or cell-split support 5) VStrip...still experimenting... 6) m2apx3g...no cell-split or subtitle support from what I can figure out. ...was wondering if any of you could provide your experiences with VOB ripping utilities and commandline parameters. I am still trying to figure our DVD2AVI. It would be nice to have all of this in one program and demux all in one pass (all streams) but I realize that I may have to first demux to new VOBs and then try and decode as a second or third pass. Thanks to everyone...playa.
