Alex Converse 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.

Martin Storsjö 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.

This facilitates stream copy from formats that don't set frame_size.

Martin Storsjö 7072a6a4bb pktdumper: Use usleep instead of sleep
MinGW doesn't have sleep, only _sleep (which is deprecated),
Sleep (which is defined in winbase.h and not in the standard
C headers) and usleep.
