It is not available on all systems and using argc/argv directly actually
makes the code simpler.

A compile-only test could succeed with an implicit function declaration.
Also move the check to the x86 section; rdtsc is x86-only.

Make sure that an output frame has really been produced before returning
0.

Also make this the default value.

This is required for CommandLineToArgvW. Normally, shellapi.h is included
implicitly by windows.h, but if we define WIN32_LEAN_AND_MEAN (or some of
the other earlier headers have included windows.h with that option),
windows.h doesn't include this one.

Thus explicitly include the headers we really need, for clarity and
compatibility.

Only return an error if memory allocation fails or error recognition is
set to explode. Otherwise just print an error message and continue
reading the file.

This way we don't end with an invalid stream if parsing the picture
fails.

Also replace x>>av_log2(sizeof(..)) + 1 by x/sizeof(..). The +1 is
probably meant to emulate av_log2_ceil(sizeof(..)) in cases where ".."
is not a power of two.

The SPLATB_REG macro already adds the 'd' suffix internally.

This fixes building on Win64, which has been broken since 878e6690.

This worked for unix, where r2 happened to be rdx in this case, which
with the first suffix rdxd was mapped to eax, and eaxd is defined back
to eax. On win64 however, r2 happened to be R8 in this case, and
R8d mapps to R8D just fine, but there's no mapping for R8Dd to anything.

Input on/off state can change in request_samples(), which can result in
a state where only the first input is active. get_available_samples()
will then return 0, and request_frame() will fail with EAGAIN even
though there is data on the single active input.

Take this into account and check the number of active inputs again after
calling request_samples().

0 should only be returned when there was at least one output frame.

start time is already substracted from the frame timestamp, so it needs
to be checked against 0, not start time.

This avoids creating new AVStreams for them when switching between
different variants of them, since we can handle changes between
different sample rates of nellymoser within the same stream.
