They were introduced in an earlier commit that introduced use of named
arguments. One cause was a typo, a second cause appears to be a bug in
x264asm that I work around by not using named arguments.

If muxing into mpegts, 4 byte startcodes for the first NAL
of an access unit is required. Thus it is simplest for the
RTP depacketizer to just use 4 byte startcodes everywhere.

This avoids unused variable warnings when zlib/bzlib are not available.

This allows dropping the av_unused argument from them.

Recent versions of gcc (4.4+) no longer give false positive warnings.

When segmenting the output from the mpegts muxer, one can
now set this option when cutting to a new segment, to make sure
the next segment starts with PAT/PMT/SDT.

This allows removing any gray16-specific code, which is essentially
identical to the per-plane code in yuv2plane*().

Also give a more suitable name to the MMI-optimized IDCT;
it is not PS2-specific, as the name currently suggests.

This fixes compilation with -Werror=missing-prototypes.

"dstw" can collide with the word-version of the "dst" argument, causing
all kind of weird stuff down the pipe.

Most of the function had been converted before, but I forgot this
particular location.

Set output files duration to recording_time option, if given.
Rationale: to save duration into metadata for file that is written to
non-seekable output, for formats like FLV (with metadata at beginning).

At very small dimensions, this calculation could lead to zero-sized
filters, which leads to uninitialized output, zero-sized allocations,
loop overflows in SIMD that uses do{..}while(i++<filtersize); instead
of for(i=0;i<filtersize;i++){..} and several other similar failures.
Therefore, require a minimum filtersize of 1.

Simplifies use of verbatim mode.

Otherwise it is not needed because it matches the frame size as encoded in
the extradata.

This avoids an indirection and will simplify implementation of encode2()

Gives a better estimate of buffer requirements and a better decision of
whether or not to use verbatim mode.
