3 "size of output buffer"
8 Increase this if you encounter output buffer overrun
9 errors. Smaller values make the mp3dec filter use less
10 memory. The minimal size is 32K.
15 "ignore CRC information in the audio stream."
18 This causes frames with CRC errors to be decoded and played
19 anyway. This option is not recommended, but since some encoders
20 have been known to generate bad CRC information, this option
21 is a work-around to play streams from such encoders.
