c8dc5a0980 Parsing of unsupported MP3 streams improved 
- For supported MP3 streams, all frame header information must be the
same for the whole stream.
- For unsupported MP3 streams, this has been removed and only the stream
type has to be the same. This will lead to some more false positives,
but give longer streams, so the log is not bloated with thousands small
false positives

down the process for non-MPEG-1, Layer III MP3s
