A Patch for mpg123 on 486DX PCs
Why not use your old 486 PC as a jukebox ? This is now possible with
this patch to mpg123 which may enable it to play MPEG audio layer 3
(.mp3) files in real time. Note that this optimization is only
currently supported for Linux.
The newest version (patch level 1) can play MPEG audio layer 3 files
at 22.1 kHz in stereo even on a 486DX2/66.
The following table gives the performance of mpg123-486pl1 on an
MPEG audio layer3 file at 112 kbit/s.
| Processor || 22 kHz - stereo || 44 kHz - mono ||
44 kHz - stereo
| 486DX50 || No (almost !) || OK (80% CPU) || No
| 486DX2/66 || OK || should work || Not yet (almost !)
| 486DX4/100 || OK || OK || OK
