The size check must be updated to take into account both manners

cd14e297e6 prores: do not set pixel format on codec init 
The pixel format is not known until the frame header is parsed.
Guessing it here only causes trouble for the caller if the guess
turns out to be wrong (and actually causes very wrong output by
avconv/avplay).

d341d5fd2c dnxhdenc: fixed signed multiplication overflow 
The low 32 bits of a multiplication are the same for signed
and unsigned operands.  Casting to unsigned before multiplying
is thus equivalent while avoiding signed overflow, which is
undefined by the C99 standard.

2c4e08d893 riff: always generate a proper WAVEFORMATEX structure in ff_put_wav_header 
The cbSize field should be included in all cases, even with PCM where
its value is ignored.

Fixes encoding PCM audio in Matroska for some players which insist on
a full WAVEFORMATEX structure for A_MS/ACM audio.

Since fate uses wav files for the audio test a larger number of tests
has changed checksums or shifted positions due to the 2 byte longer
wave header.

e32dfdaa8d shn: do not allow seeking in the raw shn demuxer.

full decode, and no shorten decoder can handle random seeking because it needs
side info from the seektable.

b45eb9d619 pcm: reduce pointer type casting 
Making 'samples' a pointer to uint8_t simplifies the DECODE
macro and reduces the amount of type casting overall.

This also fixes some signed overflows on left shift.
