#!/bin/bash
# Author : Nacos
# License : do what the fuck you want with it

# Depends on ffmpeg and subliminal(https://pypi.python.org/pypi/subliminal/)

# My TV has a shitty implementation of DLNA and cannot handle .srt subtitle located next to my episodes
# For each file matching *.mp4, I execute the following steps :
# First, I try to download the right subtitle using subliminal if I don't have it
# Then I use ffmpeg to "merge" the video file and the softsub into a single mkv file

# Subtitle should still be a softsub (it's not "burned" into the video file"), so be sure your media player is capable is reading it

# usage : ./prepareDLNA.sh /path/to/series/folder


# Script below
# Bear with me, code is far from being perfect
