The tests also test the other dispositions: commentary, descriptions
as well as dub and original language.

The first version of the matroska-wtv-remux test used the fixed-point
mp2 decoder; given that no floats are involved I presumed that this
would give reproducible results among different arches. I was wrong [1].
Therefore this version uses only streamcopy.

I intend to apply this patchset tomorrow.

How is this possible?

I just had a second look and I think I was wrong about the culprit. Here
is the diff from ppc from Andriy:

Test matroska-wtv-remux failed. Look at
tests/data/fate/matroska-wtv-remux.err for details.
tests/Makefile:255: recipe for target 'fate-matroska-wtv-remux' failed
make: *** [fate-matroska-wtv-remux] Error 1

Stream 3 is the hearing impaired stream. It is also completely blank
(consists only of zeroes after decoding); stream 4 is the ordinary audio
track (also mp2) decoded to pcm_24be. There is no dif for it. So it
seems to be the alac encoder, something which I had not considered
previously because this is a lossless encoder. But now I looked and
there are doubles in ff_lpc_calc_coeffs, but this code is only used if
compression_level == 2 (the default). I will give this another try by
setting it to 1.
