play sequences for each item of a playlist

[cjegx]

I have a playlist of N files.

Is it possible to define, for each item of the list :
to play not the full file from the start to the end, but to play one or MANY sequences ?

Each sequence would be defined graphicaly by a "from HH:MM:SS to HH:MM:SS".

It would be a very convenient way to show automatically to an audience, the best sequences in a set of video files.

Thanks !
