Change:
Expected 7 arguments, but only %d found in '%s'\n
to:
Expected 7 arguments, but %d found in '%s'\n

as the user may provide more than 7 arguments, in that case the error
is not misleading.

The encoder has never produced files that could be decoded
with any software and there should be no reason to create
such files anyway.

Channel coupling is an optional AC-3 feature that increases quality by
combining high frequency information from multiple channels into a
single channel. The per-channel high frequency information is sent with
less accuracy in both the frequency and time domains. This allows more
bits to be used for lower frequencies while preserving enough
information to reconstruct the high frequencies.

In -std=c99 mode GCC defines __STRICT_ANSI__ to hide non-ANSI interfaces.
This causes declarations for some POSIX functions to be omitted from system
headers, which causes compilation failures.

The sample on rsync was corrupt, this one is now bitexact w.r.t. JM.

Currently, the url_interrupt_cb callback will abort all IO
after the first received signal. This makes the output files
from e.g. the mov muxer to be unreadable if the transcode is
aborted with ctrl+c.

After this patch, the first signal cleanly breaks out of
the transcoding loop, but won't forcibly abort all IO.
After the second signal is received, the url_interrupt_cb
callback will abort all IO.

This avoids doing a division by zero if the option wasn't found,

It's badly documented and does the same thing as -flags global_header,
so it's redundant.

Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

Else a later buffer resize in ffio_set_buf_size() will ABORT.

If done before, some parameters aren't known yet.

With svq3/rtp, initializing before some parameters are known
can lead to calling av_malloc(0), which on OS X currently returns
broken pointers.

This explicitly disables threading for encoding as slices are otherwise
automatically activated.  This should be dropped once option resetting

Since a private class is set for this muxer, the callers will
assume that the private data starts with an AVClass pointer.
If no such member exists, the first few bytes of the struct
will be overwritten, and the class pointer may be broken at
any later time.

When backing up the top-left border, check that the top-left
(rather than left) MB indeed does belong to our slice. If it
doesn't, backing up has no positive effect but may accidentally
interfere with other threads writing in the same space.

Fixes occasional one-off effects when enabling slice-MT.
