It might be that you're hitting a bug with the gapless decoding code. Or, well, perhaps a documentation issue, depends on my final interpretation;-)
Could you disable gapless decoding and repeat your experiment:

mpg123_param(hMp3, MPG123_REMOVE_FLAGS, MPG123_GAPLESS, 0.);

Thing is that the gapless code tries to hide the complexity of having to decode some leading frames to get reproducable output (MP3 frames depend on predecessors). So, for example, when getting frame 300, it seeks to 298 and decodes the leading frames into emptyness before getting to the actually wanted frame. I can imagine that your special case trips a bug with that behaviour.


Alrighty then,

Thomas.
