d51d6ae9c4 vc1dec.c: Don't use uninitialized values of dmv_[x, y] 
MVDATA may or may not be transmitted. If it is not, both
dmv_x and dmv_y is to be assumed zero.

This may not trigger wrong picture in all systems, but
it's a bug nevertheless. Fixes SA10116.vc1 on my 64-bit
Windows 7.

b3461c29c1 lavf: prevent infinite loops while flushing in avformat_find_stream_info 
If no data was seen for a stream decoder are returning 0 when fed with
empty packets for flushing. We can stop flushing when the decoder does
not return delayed delayed frames anymore. Changes try_decode_frame()
return value to got_picture or negative error.

d78bb1a4b2 wma: Clip WMA1 and WMA2 frame length to 11 bits. 
The MDCT buffers in the decoder are only sized for up to 11 bits. The
reverse engineered documentation for WMA1/2 headers say that that for
all samplerates above 32kHz 11 bits are used. 12 and 13 bit support
were added for WMAPro. I was unable to make any Microsoft tools generate
a test file at a samplerate above 48kHz.
