#
# dcp_inspect is a tool for deep inspection and validation of digital
# cinema packages (DCP). This includes integrity checks, asset inspection,
# schema validation, signature and certificate verification, composition
# summaries and naming convention checks.
#
#
# Usage:
#
# dcp_inspect --help
# dcp_inspect /path/to/dir
# dcp_inspect /path/to/dir --no-hash
#
#
# Installation:
#
# See https://github.com/wolfgangw/digital_cinema_tools_distribution/wiki
# for an easy-to-use setup script. This will install everything required.
#
#
# Features:
#
# - Will find and check all DCPs in a filesystem tree
#
# - Runs schema validation on all infrastructure files and DCSubtitle.
# Validation errors will be reported but dcp_inspect will still try to
# inspect the contents of non-valid files.
#
# - Checks and verifies signatures
#
# - Reports detailed composition overviews
#
# - Deep-inspects compositions. This includes composition type consistency
# and completeness checks. dcp_inspect goes through some lengths to determine
# a composition's type (SMPTE/Interop).
#
# - Hints at deviations from the Digital Cinema Naming Convention.
# See http://digitalcinemanamingconvention.com for the proper nomenclature
#
# - Checks presence and sanity of DCSubtitle resources
#
# - Reports in detail all errors encountered
#
# See [Examples](https://github.com/wolfgangw/backports/wiki/Example-output-from-dcp_inspect).
#
#
# Manual installation / Requirements:
#
# If you prefer manual installation you will need the following:
#
# - $ git clone git://github.com/wolfgangw/backports.git
# - asdcplib and its cli tools (http://www.cinecert.com/asdcplib/)
# - Nokogiri, a ruby wrapper for libxml2
# (http://nokogiri.org/tutorials/installing_nokogiri.html)
# For signature verification dcp_inspect requires a recent
# (post 2012.01.11) Nokogiri version with C14N support.
# - dcp_inspect requires xsd/ next to it.
# Clone the whole repository to put everything in place:
# $ git clone git://github.com/wolfgangw/backports.git
#
# Run
# $ git pull
# in backports to keep up-to-date.
#
#
# And then what?
#
# - If you get errors go bug someone:
#
# Either me (https://github.com/wolfgangw/backports/issues) if you
# suspect dcp_inspect to report a false positive or negative
#
# or the author/vendor of the DCP's authoring app.
#
# We all write bugs all the time and your feedback is much appreciated.
#
# - If you get hints think about bugging someone. Try and make an informed
# decision whether the issues hinted at might lead to trouble in the field.
# Some hints will recommend fixing the issue (e.g. empty Text or Image
# elements in DCSubtitle). Other hints will be purely informational
#
# - If all you get is info and 0 errors:
#
# Either your package is perfectly ok
#
# or you might still run into issues on a system in the field
#
# or you ran into a dcp_inspect bug :) Again, get in touch if you suspect
# the latter (https://github.com/wolfgangw/backports/issues).
#
#
# Thanks to the Nokogiri team. You're a wicked crew.
# Thanks to Julik for his Timecode library
# https://github.com/guerilla-di/timecode
# Thanks to Mattias Mattsson for DCSubtitle.v1.mattsson.xsd and
# great feedback from Göteborg International Film Festival.
# Thanks to Mike Radford and Tammo Buhren for test materials.
# Thanks to Alexis Michaltsis for interesting test cases and feedback.
# Thanks to Lilian Lefranc for constant feedback and a donation
# which clearly exceeded what can safely be called a gesture.
# Appreciated and you rock.
# Thanks to Adrianne Jorge for a great user report from Sundance and Sarasota.
#
# Tested on linux and Mac OS boxes. Thanks to Terrence Meiczinger for trying
# on a Windows system (it executed but the libxml infrastructure required for
# schema validation did not work. Wip)

# lib/timecode-ticks_tc.rb (Julik's timecode -- https://github.com/guerilla-di/timecode + parse_with_ticks)
# Timecode is a convenience object for calculating SMPTE timecode natively.
# The promise is that you only have to store two values to know the timecode - the amount
# of frames and the framerate. An additional perk might be to save the dropframeness,
# but we avoid that at this point.
#
# You can calculate in timecode objects as well as with conventional integers and floats.
# Timecode is immutable and can be used as a value object. Timecode objects are sortable.
#
# Here's how to use it with ActiveRecord (your column names will be source_tc_frames_total and tape_fps)
#
# composed_of :source_tc, :class_name => 'Timecode',
# :mapping => [%w(source_tc_frames total), %w(tape_fps fps)]
