The code was setting aspect ratio from the DTG active format, and was
present and disabled since the creation of ffplay.

The colon operator of expr always anchors the pattern at the start
of the string. An explicit ^ in the pattern has unspecified
behaviour, so remove it.

Some MPEG4 cameras produce files with empty GOP headers.
This patch makes the decoder ignore such broken headers and proceed
with the following I-frame. Without this change, the following
start code is missed resulting in the entire I-frame being skipped.

This makes the cc_ident value, which is used in FATE reports, include
all interesting parts of the gcc version string.

There is a check for HAVE_BIGENDIAN when outputting the IEC 61937
stream. On big-endian systems the payload data is not byteswapped,
causing in effect the outputted payload data to be in a different byte
order on big-endian than on little-endian systems.
However, the IEC 61937 preamble (and the final odd byte if present) is
always outputted in the same byte order. This means that on big-endian
systems the headers have a different byte order than the payload,
preventing useful use of the output.
Fix that by outputting the data in a format suitable for sending to an
audio device in S16LE format by default. Output as big-endian (S16BE)
is added as an AVOption. This makes the muxer output the same on all
archs by default.

This fixes visual glitches in Bink version 'b' files, as the quantization
tables were not being permuted.

When built with gcc 4.6, the MMX rgb24 to yuv conversion gives
wrong output. The compiler produces this warning:
libswscale/swscale_template.c:1885:5: warning: use of memory input without lvalue in asm operand 4 is deprecated
Changing the memory operand to a register makes it work.

Using doubles make the double -> int cast well defined for all the values
used, with the exception of when s[i]==1.0, which is special-cased.

In the FAQ section "How do I encode single pictures into movies?", use
-s for generating symbolic links with the ln command.
The script was generating hard links, which is not likely what it was
supposed to do.
Fix issue 2488.

This is used for mapping AVStreams back to their corresponding
RTSPStream. Since d9c0510, the RTSPStream pointer isn't stored in
AVStream->priv_data any longer, breaking this mapping from AVStreams
to RTSPStreams.
Also, we don't need to clear the priv_data in rdt cleanup any longer,
since it isn't set to duplicate pointers.

The early disabling of irrelevant arch extensions is no longer
required, and removing it makes dependencies involving these
work as expected.

s->windowed_samples will always have a range of [-32767,32767] due to the
window function, so the return value from log2_tab() will always be in the
range [0,14].

This code will be later split out into a function which takes a 'size'
argument, so I'm keeping the name 'sizeX' here.
