    swscale: remove sws_format_name()

    Use av_get_pix_fmt_name() instead.

The symbol is used by some external libs (hi libx264!), this gives
time to them to use the recently added av_get_pix_fmt_name() rather
than an internal symbol.

Propagate av_vsrc_buffer_add_video_buffer_ref() error code rather than
return 0.

Clarify code layout.

The comment is meant to be about the align parameter.

Adopt K&R style for overall consistency/readability.

postprocess: Remove test for impossible condition (was: Re: postprocess.c: replace check for p==NULL with *p==0)

Given that this compiles fine with the Apple compiler that is probably
a gcc bug, but "const vector" is nicer anyway.

Also include an older fix for vf_smartblur which was essentially
broken due to reading the threshold value wrongly.

Since this is only a compilation check (the actual function used is
selected at runtime) and HAVE_SSE indicates that we can also compile
SSE2 code, this is correct.

Fixes compiler warning about incompatible types in sws_scale call.

Some parameters passed to the av_dlog can be either float or int, depending on
the mode the file is being compiled as.  Cast those parameters to float and use
appropriate conversion specifiers.

This is required after sws_format_name() was replaced by
av_get_pix_fmt(), which is declared in libavutil/pixdesc.h.

This makes the generated Doxygen doc link to the replacement
av_dump_format() function.

The yuv4mpeg muxer will crash otherwise.

Store AVPicture in AVPacket as required by AVFMT_RAWPICTURE formats.

Fix trac issue #251.

Rename:
api-example.c    -> encoding-example.c
output-example.c -> muxing-example.c

Fixes regression in 836f47d3 in ICC-10.x,
since ICC<=11.0 doesn't align stack upon function calls.

Ports the majority of IDCT functions for 10-bit H.264.

Parts are inspired from 8-bit IDCT code in Libav; other parts ported from x264 with relicensing permission from author.

Prior to ARMv6, the destination registers of the SMULL instruction
must be distinct from the first source register.  Marking the
output early-clobber ensures it is allocated unique registers.

This restriction is dropped in ARMv6 and later, so allowing overlap
between input and output registers there might give better code.

The 'edts' write function can now generate an initial empty edit resulting in a track-specific presentation delay.
This is automatically calculated and inserted for any track where the initial DTS != 0.
Added support for long (version==1) timecodes.

This merges the float and fixed-point versions of the compute_antialias
function, fixes invalid array indexing, and eliminates a dead copy of
csa_table.
