As this is depricated it should not be on by default, it is only
supported for MOV containers, depends on avpriv_get_gamma_from_trc()

Enable by:

-movflags +write_gama

This will use the color_trc to supply a gamma value, if desired an
explicit value may be supplied using the -mov_gamma option supplying
a suitable floating point value, values <=1e-6 will not be written.

s->listen_timeout is passed to ff_listen_bind(), which accepts a timeout
value expressed in milliseconds.

The unit was incorrectly set in 1b4da43c.

While the native jpeg2000 decoder can determine pixel format correctly
from the codestream, libopenjpeg wrapper cannot. To make sure that
the output is correct when using libopenjpeg to decode digital
cinema files, we do detection from the metadata included in the MXF
wrapper.

If the container has "JPEG 2000 Coding Parameters" metadata element
with Rsiz value set to one of digital cinema profiles, we can safely
assume that the given input file is DCI compliant, therefore the
pixel format should be XYZ.

Depending on FPS, the pts_time string often changes length:
... pts_time:36.1 ...
... pts_time:36.1333 ...
etc.

 The length changes make the output bounce around horribly, making it
hard to scan down a column farther right than pts_time.

The solution is to set minimum widths for n, pts, pts_time, and pos.
This patch doesn't touch any of the fields in mean / stddev.

 The widths aren't intended to be wide enough that they're never
exceeded, but you'll see only an occasional ripple to a new alignment,
rather than bouncing.  (Some fields, like pos, increase monotonically,
which is why I left the minimum width for the field be smaller than it
often gets to.)

And provide a more informative message in case of failure.

CC: libav-stable@libav.org

Although the specification mandates this bit to zero, it may happen
that software tools incorrectly flip it to one, invalidating a possibly
valid stream.

Relax this restriction, by failing only when AV_EF_BITSTREAM is set.
This behaviour is similar to aac decoders in Firefox and Quicktime.
