Error playing mp3 file using dshowdecwrapper (dshowadec_mp3)

[Michael Smith]

It may be that the warnings you showed us were because part of your
file isn't mp3 (e.g. perhaps you want id3demux before mp3parse?), but
then something else goes wrong with the actual decoder that is
unrelated to that.

Unfortunately the debug output you provided had no information about
this at all. Perhaps you can increase the debug level to 5 and see if
there's any more useful information there.
