New submission from Bob <[email protected]>:

I am using only the parser part of ffmpeg. While playing WMA VOICE or WMA PRO
files, the extradata variable under stuctutre 'AVCodecContext' gets filled up.
(I required the extra data to look for Advenced Encode option required by WMA
PRO decoder).
But compared to the output generated by 'asfviewr' (as MS utility to view asf
headers), the extradata dump is about 18 bytes less. Within the ffmpeg code
(wmadec.c etc) is even gives warnings to denote that the data received isnt 
enough.
Something like: [wmavoice @ 0x1b5770]Invalid extradata size 28 (should be 46)
Are the 1st 18 bytes before the extradata dumpe being used elsewhere?
Are WMA PRO Advanced Encode Options stored somewhere else?
Any inputs would be helpful.
