From dc521b5d48e11fbccbea07b450e21f63c28066ef Mon Sep 17 00:00:00 2001 From: Thomas Martitz Date: Mon, 18 Oct 2010 18:55:31 +0000 Subject: Replace parse_testcodec.pl with a bit more powerful script. It can compare more than one result file at a time giving additional speedup colums, is more robust (RaaA results don't have the "MHz needed for realtime" line which is handled with this one) and has a mode to output the results in a form readable by spreadsheet software for nice graphs. Needs Ruby 1.9.x git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28305 a1c6a512-1295-4272-9138-f99709370657 --- utils/parse_testcodec.rb | 284 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 284 insertions(+) create mode 100755 utils/parse_testcodec.rb (limited to 'utils/parse_testcodec.rb') diff --git a/utils/parse_testcodec.rb b/utils/parse_testcodec.rb new file mode 100755 index 0000000..9a2a6e9 --- /dev/null +++ b/utils/parse_testcodec.rb @@ -0,0 +1,284 @@ +#!/usr/bin/ruby +# (c) 2010 by Thomas Martitz +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2 of the License, or +# (at your option) any later version. + +# +# parse test codec output files and give wiki or spreadsheet formatted output +# +class CodecResult + include Comparable +private + + attr_writer :codec + attr_writer :decoded_frames + attr_writer :max_frames + attr_writer :decode_time + attr_writer :file_duration + attr_writer :percent_realtime + attr_writer :mhz_needed + + def get_codec(filename) + case filename + when /.+aache.+/, /nero_he_.+/ + self.codec = "Nero AAC-HE" + when /a52.+/ + self.codec = "AC3 (A52)" + when /ape_.+/ + self.codec = "Monkey Audio" + when /lame_.+/ + self.codec = "MP3" + when /.+\.m4a/ + self.codec = "AAC-LC" + when /vorbis.+/ + self.codec = "Vorbis" + when /wma_.+/ + self.codec = "WMA Standard" + when /wv_.+/ + self.codec = "WAVPACK" + when /applelossless.+/ + self.codec = "Apple Lossless" + when /mpc_.+/ + self.codec = "Musepack" + when /flac_.+/ + self.codec = "FLAC" + when /cook_.+/ + self.codec = "Cook (RA)" + when /atrac3.+/ + self.codec = "Atrac3" + when /true.+/ + self.codec = "True Audio" + when /toolame.+/ + self.codec = "MP2" + when /atrack1.+/ + self.codec = "Atrac1" + when /wmapro.+/ + self.codec = "WMA Professional" + when /wmal.+/ + self.codec = "WMA Lossless" + when /speex.+/ + self.codec = "Speex" + else + self.codec = "CODEC UNKNOWN (#{name})" + end + end + + def file_name=(name) + @file_name = name + get_codec(name) + end + +public + + attr_reader :file_name + attr_reader :codec + attr_reader :decoded_frames + attr_reader :max_frames + attr_reader :decode_time + attr_reader :file_duration + attr_reader :percent_realtime + attr_reader :mhz_needed + + # make results comparable, allows for simple faster/slower/equal + def <=>(other) + if self.file_name != other.file_name + raise ArgumentError, "Cannot compare different files" + end + return self.decode_time <=> other.decode_time + end + + def initialize(text_block, cpu_freq = nil) + # we need an Array + c = text_block.class + if (c != Array && c.superclass != Array) + raise ArgumentError, + "Argument must be an array but is " + text_block.class.to_s + end + + #~ lame_192.mp3 + #~ 175909 of 175960 + #~ Decode time -
