skiptro

Ever find yourself watching your non-pirated media and wishing it has the Netflix "skip intro" button? Well, this is as close it gets.

skiptro analyzes your media library and tries to find common sequence in the first 5 minutes of the files. Then, it creates an EDL file (and .m3u playlist) which most players know how to interpret to skip to a particular time in the media file.

Usage

To create skip file for the "target" file by comparing it to the "source" file:

skiptro -source TheOffice/S01/E02.mp4 -target TheOffice/S01/E03.mp4

If using VLC, use the .m3u file produced to auto-skip the intro. Kodi will automatically detect the EDL file produced and skip the intro accordingly.

Flags

Flag	Description	Default
duration	Length of search time	10m
hashtype	Hash algorithm to be used (perception, difference, average)	difference
fps	Samples per second to extract for comparison	3
tolerance	Similarity between frames (lower = more similar)	15
workers	Workers to spin for JPEG processing	NumCPU (ex. 8)
skipfile	Create EDL and M3U skip files next to the target	true
debug	Profile and output debugging artifacts	false

Status

Not suitable for mass library usage yet. Can be used to manually create the skip files.

Features missing

Full directory processing
Daemon mode which scans for new files and processes them automatically
