Example


fadedet -videoDir /opt/Movies/ForrestGump/ -videoName ForrestGump.mpg

As a result two file will be generated:
/opt/Movies/ForrestGump/measurements/fadeDetection/fadeDetection and /opt/Movies/ForrestGump/measurements/fadeDetection/fadeDetection.range.
For your purpose fadeDetection can be deleted. fadeDetection.range contains all you need. It is a ASCII file of the form

    1 200000
    Fade in 30 63
    Fade in 1116 1136
    Fade out 3243 3291
    ....

Each text line but the first specifies the type and range of a fade. The first text line gives the number of the first and last frame of the search range.
