Looks like this kind of samples are produced by certain Russian

Snow is a toy codec with no real-world use and horrible code.

Original commit, 7b24f9b, says it was added because it is used in libnut.

fixes Bug 392

The table is not used outside the file.

This fixes compilation with --disable-muxers.

This matches the value for the plain WAVEFORMATEX header.
Also fixes stream copy to WAVE for non-16-bit raw pcm.

For encoding, frame_size is not a reliable indicator of packet duration.
Also, we don't want to have to force the demuxer to find frame_size for
stream copy to work.

They are deprecated and will be purged on next major bump.

This requires some workarounds in the WAV muxer and demuxer. We need to write
the correct bits_per_coded_sample and block_align in the muxer. In the
demuxer, we cannot rely on the bits_per_coded_sample value, so we use the bit
rate and sample rate to determine the value.

This avoids having the decoder rely on AVCodecContext.bit_rate, which is not
required to be set by the user for decoding according to our API.

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.

This fourcc is used by the "mpegable AVC" codec and files encoded with
this codec decode correctly with our H.264 decoder.
