Remove the CODEC_CAP_LOSSLESS flag, as it doesn't make
any sense for a decoder to use it.

Since buf_size is only used in this one function, there
is no reason for it to be part of UtVideoContext.

The caller expects the seekhead struct to be freed when calling
matroska_write_seekhead. Currently, the structure is leaked if the
seek fails.

run: The number of zero coefficients preceding a non-zero coefficient,
in the scan order. The absolute value of the non-zero coefficient is
called "level".

The run-level code makes illegal reads when trying to set up tables for
nonsense level 0.

It might make sense not to make the function completely mandatory

The original format field in Ut Video's extradata
should not be used to determine the output format.
Cases can occur where the original format differs
from the actual current format, and thus should
not be used as the output format. Instead, rely
solely on the FOURCC.

The new design allows to specialize the format for continuos time values
and discrete values. In particular, allows to print integer values like
"12" rather than "12.000".

Prettify, simplify parsing for integer values.

Help readability.

This makes rdt work again, which has been broken since
603b8bc2. This commit made
opening a demuxer without a file (or in this case, with a filename
which can't be opened) fail, unless the demuxer actually declared
AVFMT_NOFILE.

If it failed, return NULL. This avoids trying to use an
