The option is enabled by default, but can be disabled.

If this is enabled, such side data isn't copied into the output stream
(except when doing stream copy).

This avoids a segfault in avconv_opt.c:opt_target when trying to
determine the norm.

This makes it more clear what is this variable for exactly.

Move the dxva check after the dependencies have been detected, make sure
the ole32 library exists.

Fixes build on non-Windows.

avio_open2() only return < 0 when error.

Fixes an assertion failure in vdpau_get_buffer() when -hwaccel auto is
used, but hwaccel init fails.

Quite useful for debugging.

It limits the duration of the data read from a given input.

Insert (a)trim filters on the corresponding inputs, so the extra frames
are decoded and discarded.

Using -ss 0 to drop frames with negative timestamps is a perfectly valid
use case.

It is incompatible with refcounted frames and since it's been deprecated
for a long time now, fixing it is not worth the effort.

Hack partially based on a commit by Michael Niedermayer <michaelni@gmx.at>
Should fix (or work around) bug 458.

This way OutputFile variables like recording time can be used when
creating the streams.

We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

There are never any packets for those streams.
Fixes an infinite loop with -attach.

Print an error and abort when the option is of the wrong type (decoding
for output file or vice versa), since this could never be correct for
any input or output configuration.

Print a warning and continue when the option is of the correct type,
just unused, so same commandlines can be reused for different kinds of
input or output files.

This is shorter and more readable.

This is shorter and more readable.

I.e. input options to output files or vice versa.
