[vorbis-dev] Test: Lame vs. Ogg/Vorbis -- warning big mail
Hi there.
First of all, I'd like to congratulate to developers
for making a free specification and LGPLed
decoder/encoder. :-).
I did some test, ripping 17 tracks of my CD and
converting them to both MP3 and OGG format.
MP3 encoder/player was Lame 3.70
OGG encoder/player was from a Saturday nightly
tgz package.
------------------------------------
MP3: LAME-3.70 mpg123-0.59r-4
MP3: lame -S -b 128 $FILE $OUT_FILE.mp3
Ogg: Vorbize-0.2 (Xiphophorus libVorbis I 20000508), ogg123-0.1
Ogg: /opt/ogg/bin/vorbize -q -w $OUT_FILE.ogg $FILE
ENCODED SIZE:
-------------
Total filesize report is:
80740 ogg files
71818 mp3 files
791391 wav files
Vorbis shrunk WAV files to 10,2%
Lame shrunk the WAV files to 9,1%
ENCODE SPEED:
-------------
Vorbis needed somewhere from 4 - 5 times more
time than lame to encode a file.
(text report from my script is appende later in this mail)
DECODE SPEED:
-------------
OK.. not speed.. CPU usage :-) on a K6-188
-> ogg123:
176.56user 1.44system 5:01.00elapsed 59%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (1229major+280minor)pagefaults 0swaps
-> mpg123:
50.57user 3.50system 5:00.65elapsed 17%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (2396major+116minor)pagefaults 30swaps
COMMENTS:
----------
For Alpha software Ogg/Vorbis is great.
OGG size is comparable to MP3 size (will this improve?),
OGG encode speed is comparable to l3enc and will most likely improve
with time (after all lame wasn't developed in 24 hours).
But the playback CPU usage is what is not 'nice'. There I think is
a problem as ogg123 needs 3x more CPU power to decode
than mpg123. But I hope this will also change with further development.
To be fair:
Ogg/Vorbis is free and LGPLed and that beats the crap out of MP3,
no matter the speed/size arguments.
