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.

9f9c45f4b6 movenc: Don't require frame_size to be set for modes other than mov 
The field frame_size isn't written to the output anywhere except
than in mov.
