# split2components.sh - Script for splitting video files into components
|
|
################################################################################
|
|
# This script processes video files, extracts video streams to MKV format,
|
|
# extracts subtitles to SRT format, and converts audio streams to separate FLAC files.
|
|
# It supports various video file formats like MP4, MKV, AVI, FLV, and MOV.
|
|
# The script requires ffmpeg and pv to be installed on the system.
|
|
#
|
|
# Usage: ./split2components.sh <target_path>
|
|
# - <target_path>: The path where the files will be processed and components stored.
|
|
#
|
|
# Dependencies:
|
|
# - ffmpeg: A multimedia processing tool (https://ffmpeg.org/)
|
|
# - pv: A terminal-based tool for processing data (https://www.ivarch.com/programs/pv.shtml)
|
|
#
|
|
# Note: Make sure to install the required dependencies before using this script.
