About previous work: your suggestion is an Edit Decision List, enriched
with transitions. The Wikipedia page 
https://en.wikipedia.org/wiki/Edit_decision_list lists a number of
players that support EDL. Mplayer/mpv have a basic text-based format.
VLC is mentionned through XSPF support, but I do not think XSPF
supports specifying a start time for a resource.
VLC also supports the DASH specification, which is used for adaptive
streaming of videos but offers the necessary features for implementing
your ideas (minus the transitions), you would only have to generate an
appropriate XML file. And I did not follow the VLMC development (VLC-
based movie editor) to know if they would support using a text-based

Research wise, this can be further abstracted through the notion of
video annotations (specifying video fragments), and their visualization
in a specific way (using them to modify the playing of the video),
which can qualify as a form of hypervideo. This may be a bit far
fetched for your needs, but my application http://www.advene.org/
offers this kind of feature (minus the transitions).

> Your have a good idea abd there would be a userbase for it. Do not let go of this idea. Unfortunatly the VLC project is not the right place to start with such abstract ideas. First research needs to be done on existing and historic methods which may already acomplish this. If there are none, a draft should be written on what information such file would contain and in what manner the file is formatted. Only once that has been done does vlc, or its sister project (in early development) vlcm come into the picture to implement this.

It would suck to find out later there was already a better way to do this, or to find out the format can only work is spesific circumstances. That needs to ve avoided.
