1616	bad seek in WMV2 file	DonMoir		"Sample file:

http://sms.pangolin.com/temp/bad_seek_wmv2.wmv (3 mb)

If you do ffplay -ss 7 bad_seek_wmv2.wmv it works correctly.

But ffplay -ss 8 bad_seek_wmv2.wmv will fail with gray frame.

For my app, I see corruption and not gray.

VLC has a bit of a problem with it but not as bad.

WMP gets it perfect.

With the following you will get a gray frame and a warning about first frame is not keyframe. The first frame is a keyframe but maybe not the one it seeked to.
