> dvd:// protocol uses libdvdread for opening folders and/or disc-images,
> it then either identifies the longest title-set, or uses the title-set
> parameter.
> 
> After opening the dvd, libdvdread-protocol will read and output all
> VOBs, in the cell and pack sequence defined by the program-chain.
> 
> The (split)-VOB content that is streamed from the folder/disc by
> libdvdread, is given to ffmpeg probed demuxer/decoder, which decodes
> and presents the frames.
> 
> The chapter and language stream information is present in the
> side-files (BUP/IFO), which are parsed for identifying the correct
> main video-title-set, but not attached to the stream information.

Thanks for the new patch. All this information needs to be in the user
documentation, with a little more detail on what it means in practice
(chapters, languages, late probing, etc.).
